These warning centers issue advisories which provide basic information and cover a systems present, forecast position, movement and intensity, in their designated areas of responsibility. Meteorological services around the world are generally responsible for issuing warnings for their own country. There are exceptions, as
543-416: A 1.5 degree warming lead to "increased proportion of and peak wind speeds of intense tropical cyclones". We can say with medium confidence that regional impacts of further warming include more intense tropical cyclones and/or extratropical storms. Climate change can affect tropical cyclones in a variety of ways: an intensification of rainfall and wind speed, a decrease in overall frequency, an increase in
724-444: A 2019 review paper show a future increase of rainfall rates. Additional sea level rise will increase storm surge levels. It is plausible that extreme wind waves see an increase as a consequence of changes in tropical cyclones, further exacerbating storm surge dangers to coastal communities. The compounding effects from floods, storm surge, and terrestrial flooding (rivers) are projected to increase due to global warming . There
905-532: A Category 2 hurricane on the Saffir–;Simpson scale. It was the strongest storm in Canadian history as gauged by barometric pressure ; a pressure of 932.7 mbar (hPa; 27.54 inHg) was unofficially measured on Hart Island, setting the all-time low pressure record for any landfalling cyclone on Canadian shores. The pressure was also potentially lower than any other air pressure measurement along
1086-509: A U.S. offer of military aid against Arias, Jimenes resigned on May 7, 1916. Wilson thus ordered the U.S. occupation of the Dominican Republic. U.S. Marines landed on May 16, 1916, and seized the capital and other ports, while General Arias fell back to his inland Santiago stronghold. A significant weaponry disparity between the U.S. Marines and Arias's forces led to the latter's defeat. A peace delegation from Santiago surrendered
1267-574: A brief return to Spanish colonial status, before permanently ousting the Spanish during the Dominican Restoration War of 1863–1865. From 1930, the dictatorship of Rafael Trujillo ruled until his assassination in 1961. Juan Bosch was elected president in 1962 but was deposed in a military coup in 1963 . The Dominican Civil War of 1965 preceded the authoritarian rule of Joaquín Balaguer (1966–1978 and 1986–1996). Since 1978,

On May 2, U.S. forces were authorized to link up, and the outgunned Constitutionalists retreated to the southeastern part of the city. On May 6, U.S. diplomats persuaded the OAS to establish an Inter-American Peace Force to support American troops. The following countries volunteered: Brazil (1,250 soldiers), Costa Rica (25 police), Honduras (250 soldiers), Nicaragua (164 soldiers), and Paraguay (286 soldiers). U.S. and OAS peacekeeping troops remained in
1810-631: A figure that does not include the Dominicans, Cubans, and Puerto Ricans fighting alongside them. The Dominicans fighting for independence against Spain suffered more than 4,000 dead. Political strife again prevailed in the following years; warlords ruled, military revolts were extremely common, and the nation amassed debt. It was now Báez's turn to act on his plan of annexing the country to the United States , where two successive presidents were supportive. U.S. President Ulysses S. Grant desired
1991-405: A flow of warm, moist, rapidly rising air, which starts to rotate cyclonically as it interacts with the rotation of the earth. Several factors are required for these thunderstorms to develop further, including sea surface temperatures of around 27 °C (81 °F) and low vertical wind shear surrounding the system, atmospheric instability, high humidity in the lower to middle levels of

#17327879981702172-408: A gust of 93 mph (150 km/h). Over 80% of the island lost power. Fiona made landfall near Whitehead, Nova Scotia , on the morning of September 24 as a recently transitioned extratropical cyclone with hurricane-force winds . Environment Canada assessed Fiona's maximum sustained winds at the time of landfall to be around 105 mph (169 km/h); these winds would be comparable to
2353-506: A higher intensity. Most tropical cyclones that experience rapid intensification are traversing regions of high ocean heat content rather than lower values. High ocean heat content values can help to offset the oceanic cooling caused by the passage of a tropical cyclone, limiting the effect this cooling has on the storm. Faster-moving systems are able to intensify to higher intensities with lower ocean heat content values. Slower-moving systems require higher values of ocean heat content to achieve
2534-464: A large number of forecasting centers, uses infrared geostationary satellite imagery and an algorithm based upon the Dvorak technique to assess the intensity of tropical cyclones. The ADT has a number of differences from the conventional Dvorak technique, including changes to intensity constraint rules and the usage of microwave imagery to base a system's intensity upon its internal structure, which prevents
2715-464: A large role in both the classification of a tropical cyclone and the determination of its intensity. Used in warning centers, the method was developed by Vernon Dvorak in the 1970s, and uses both visible and infrared satellite imagery in the assessment of tropical cyclone intensity. The Dvorak technique uses a scale of "T-numbers", scaling in increments of 0.5 from T1.0 to T8.0. Each T-number has an intensity assigned to it, with larger T-numbers indicating
2896-544: A military revolt against the government of Vásquez. Desiderio Arias led a failed revolt against Trujillo and was killed near Mao in 1931. There was considerable economic growth during Rafael Trujillo 's long and iron-fisted regime, although a great deal of the wealth was taken by the dictator and other regime elements. There was progress in healthcare, education, and transportation, with the building of hospitals, clinics, schools, roads, and harbors. Trujillo also carried out an important housing construction program and instituted
3077-502: A minimum central pressure of 931 mbar (27.5 inHg) (its lowest pressure while a tropical cyclone) at 30.8°N , the lowest such value at this latitude over the North Atlantic Ocean since at least 1979. Fiona then weakened slightly, dropping to Category 3 status at 09:00 UTC, but restrengthened back to Category 4 strength six hours later; at that time, with a central pressure of 936 mbar (27.6 inHg) or lower,
3258-426: A much smaller area. This replenishing of moisture-bearing air after rain may cause multi-hour or multi-day extremely heavy rain up to 40 km (25 mi) from the coastline, far beyond the amount of water that the local atmosphere holds at any one time. This in turn can lead to river flooding , overland flooding, and a general overwhelming of local water control structures across a large area. A tropical cyclone
3439-503: A naval base at Samaná and also a place for resettling newly freed African Americans. The treaty was defeated in the United States Senate in 1870. Báez was toppled in 1874, returned, and was toppled for good in 1878. Relative peace came to the country in the 1880s, which saw the coming to power of General Ulises Heureaux . "Lilís", as the new president was nicknamed, put the nation deep into debt while using much of
3620-468: A new national record from any storm. Wind gusts across Nova Scotia recorded figures in excess of 160 km/h (99 mph), with Arisaig recording a peak of 179 km/h (111 mph). Extremely large waves reached the Atlantic coast of Nova Scotia late September 24. Buoy data indicated wave heights of 5 to 8 m (16 to 26 ft). The largest offshore waves were near and east of Fiona's path; this
3801-493: A number of techniques considered to try to artificially modify tropical cyclones. These techniques have included using nuclear weapons , cooling the ocean with icebergs, blowing the storm away from land with giant fans, and seeding selected storms with dry ice or silver iodide . These techniques, however, fail to appreciate the duration, intensity, power or size of tropical cyclones. A variety of methods or techniques, including surface, satellite, and aerial, are used to assess

He made the country debt-free in 1947. This was accompanied by absolute repression and the copious use of murder, torture, and terrorist methods against the opposition. Several Dominicans were assassinated in New York City after taking part in anti-Trujillo activities. In October 1937, Dominican troops murdered 10,000 to 15,000 Haitian men, women, and children—mostly with machetes—along
4163-414: A power outage in the entirety of Puerto Rico . All aspects of the grid were damaged, including substations and high voltage power lines. Preliminary assessments indicated the grid suffered more than US$ 2 billion in damage. The winds from the storm covered the entire island bringing heavy rainfall. That day, U.S. President Joe Biden declared a state of emergency over the hurricane. A flash flood warning
4344-422: A process known as rapid intensification, a period in which the maximum sustained winds of a tropical cyclone increase by 30 kn (56 km/h; 35 mph) or more within 24 hours. Similarly, rapid deepening in tropical cyclones is defined as a minimum sea surface pressure decrease of 1.75 hPa (0.052 inHg) per hour or 42 hPa (1.2 inHg) within a 24-hour period; explosive deepening occurs when
4525-541: A record high water height (before waves) of 2.73 metres (9.0 ft) in Channel-Port aux Basques, Newfoundland . At least 100 homes were damaged or destroyed in Newfoundland, primarily in Channel-Port aux Basques , with more than 200 people displaced. Fiona left more than 500,000 customers without power, including 80% of all Nova Scotia customers and 95% of Prince Edward Island customers. A Port aux Basques woman
4706-429: A remnant low-pressure area . Remnant systems may persist for several days before losing their identity. This dissipation mechanism is most common in the eastern North Pacific. Weakening or dissipation can also occur if a storm experiences vertical wind shear which causes the convection and heat engine to move away from the center. This normally ceases the development of a tropical cyclone. In addition, its interaction with
4887-420: A second military coup ousted the military-installed president Donald Reid Cabral . Despite tank assaults, strafing , and aerial bombardment by the opposing Loyalists, the pro-Bosch Constitutionalists maintained control of most of the capital. By April 26, armed civilians outnumbered the original rebel military regulars. Radio Santo Domingo, now fully under rebel control, began to call for more violent actions and
5068-569: A storm. Tropical cyclone scales , such as the Saffir-Simpson hurricane wind scale and Australia's scale (Bureau of Meteorology), only use wind speed for determining the category of a storm. The most intense storm on record is Typhoon Tip in the northwestern Pacific Ocean in 1979, which reached a minimum pressure of 870 hPa (26 inHg ) and maximum sustained wind speeds of 165 kn (85 m/s; 305 km/h; 190 mph). The highest maximum sustained wind speed ever recorded
5249-581: A stronger system. Tropical cyclones are assessed by forecasters according to an array of patterns, including curved banding features , shear, central dense overcast, and eye, to determine the T-number and thus assess the intensity of the storm. The Cooperative Institute for Meteorological Satellite Studies works to develop and improve automated satellite methods, such as the Advanced Dvorak Technique (ADT) and SATCON. The ADT, used by
5430-405: A system has dissipated or lost its tropical characteristics, its remnants could regenerate a tropical cyclone if environmental conditions become favorable. A tropical cyclone can dissipate when it moves over waters significantly cooler than 26.5 °C (79.7 °F). This will deprive the storm of such tropical characteristics as a warm core with thunderstorms near the center, so that it becomes
5611-529: A tropical cyclone are a result of the conservation of angular momentum imparted by the Earth's rotation as air flows inwards toward the axis of rotation. As a result, cyclones rarely form within 5° of the equator . Tropical cyclones are very rare in the South Atlantic (although occasional examples do occur ) due to consistently strong wind shear and a weak Intertropical Convergence Zone . In contrast,

5792-461: A tropical cyclone's core has a negative effect on its development and intensity by diminishing atmospheric convection and introducing asymmetries in the storm's structure. Symmetric, strong outflow leads to a faster rate of intensification than observed in other systems by mitigating local wind shear. Weakening outflow is associated with the weakening of rainbands within a tropical cyclone. Tropical cyclones may still intensify, even rapidly, in
5973-401: A tropical cyclone's intensity or the direction it is traveling. Wind-pressure relationships (WPRs) are used as a way to determine the pressure of a storm based on its wind speed. Several different methods and equations have been proposed to calculate WPRs. Tropical cyclones agencies each use their own, fixed WPR, which can result in inaccuracies between agencies that are issuing estimates on

Within the Southern Hemisphere, it is either called a hurricane, tropical cyclone or a severe tropical cyclone, depending on if it is located within the South Atlantic, South-West Indian Ocean, Australian region or the South Pacific Ocean. The descriptors for tropical cyclones with wind speeds below 65 kn (120 km/h; 75 mph) vary by tropical cyclone basin and may be further subdivided into categories such as "tropical storm", "cyclonic storm", "tropical depression", or "deep depression". The practice of using given names to identify tropical cyclones dates back to

The Northwest Pacific sees tropical cyclones year-round, with a minimum in February and March and a peak in early September. In the North Indian basin, storms are most common from April to December, with peaks in May and November. In the Southern Hemisphere,
13575-418: The Caribbean from South America during the 1st millennium BC, reaching Hispaniola by around 600 AD. These Arawakan peoples engaged in farming, fishing, hunting and gathering, and the widespread production of ceramic goods. The estimates of Hispaniola's population in 1492 vary widely, ranging from tens of thousands to 2,000,000. By 1492, the island was divided into five Taíno chiefdoms. The Taíno name for
13756-539: The Caribbean's largest lake and lowest point, Lake Enriquillo . The island has an average temperature of 26 °C (78.8 °F) and great climatic and biological diversity. The country is also the site of the first cathedral , palace , monastery , and fortress built in the Americas, located in Santo Domingo's Colonial Zone , a World Heritage Site . The name Dominican originates from Saint Dominic ,
13937-645: The Caribbean. The country did not make a military contribution to the war, but Dominican sugar and other agricultural products supported the Allied war effort. Over a hundred Dominicans served in the American armed forces. The arsenal at San Cristóbal , operated under Trujillo's regime, produced rifles, machine guns, and ammunition. Trujillo also formed a Foreign Legion of 3,000 mercenaries to attempt to overthrow Fidel Castro in Cuba. Major William Morgan agreed to lead
14118-562: The Dominican Republic has moved towards representative democracy . The Dominican Republic has the largest economy in the Caribbean and the seventh-largest in Latin America . Over the last 25 years, the Dominican Republic has had the fastest-growing economy in the Western Hemisphere – with an average real GDP growth rate of 5.3% between 1992 and 2018. GDP growth in 2014 and 2015 reached 7.3 and 7.0%, respectively,
14299-571: The Dominican Republic, but the Haitian forces were defeated after a short war. After defeating a new Haitian invasion in April 1849 at the Battle of Las Carreras , Santana marched on Santo Domingo and deposed president Manuel Jimenes (who had ousted Santana as president) in a coup d'état . At his behest, Congress elected Buenaventura Báez as president, but Báez was unwilling to serve as Santana's puppet. In November–December 1849, Dominican seamen raided
14480-577: The Dominican economy, reduced the nation's debt, built a road network that at last interconnected all regions of the country, and created a professional National Guard to replace the warring partisan units. Additionally, with grass-roots support from local communities and assistance from both Dominican and US officials, the Dominican education system expanded significantly during US occupation. Between 1918 and 1920, more than three hundred schools were established nationwide. The system of forced labour used by
14661-589: The Dominican forces had confined the Spanish troops to Santo Domingo, and the Spaniards were afraid to venture outside the capital. After nearly two years of fighting, Spain abandoned the island in July 1865. One military historian estimates Spanish casualties at 10,888 killed or wounded in action and thousands dead from yellow fever , while the Dominican forces fighting for Spain suffered 10,000 casualties. Another military historian estimates that Spain lost 18,000 dead,
14842-437: The Dominican people and land without compensation. In 1838, Juan Pablo Duarte founded a secret society called La Trinitaria , which sought the complete independence of Santo Domingo without any foreign intervention. Also Francisco del Rosario Sánchez and Ramon Matias Mella , despite not being among the founding members of La Trinitaria, were decisive in the fight for independence. Duarte, Mella, and Sánchez are considered
15023-515: The Dominican territory. The two largest islands near shore are Saona , in the southeast, and Beata , in the southwest. Smaller islands include the Cayos Siete Hermanos , Isla Cabra , Cayo Jackson , Cayo Limón , Cayo Levantado , Cayo la Bocaina , Catalanita , Cayo Pisaje and Isla Alto Velo . To the north, at distances of 100–200 kilometres (62–124 mi), are three extensive, largely submerged banks , which geographically are
15204-556: The Equator generally have their origins in the Intertropical Convergence Zone , where winds blow from either the northeast or southeast. Within this broad area of low-pressure, air is heated over the warm tropical ocean and rises in discrete parcels, which causes thundery showers to form. These showers dissipate quite quickly; however, they can group together into large clusters of thunderstorms. This creates
15385-582: The Founding Fathers of the Dominican Republic. On February 27, 1844, the members of La Trinitaria , now led by Tomás Bobadilla , declared independence from Haiti. The Trinitarios were backed by Pedro Santana , a wealthy cattle rancher, who became general of the army of the nascent republic. The decades that followed were filled with tyranny, factionalism, economic difficulties, rapid changes of government, and exile for political opponents. Archrivals Santana and Buenaventura Báez held power most of
15566-475: The French were expelled from the island and Santo Domingo returned to Spanish rule . After a dozen years of discontent and failed independence plots by various opposing groups, including a failed 1812 revolt led by Dominican conspirators José Leocadio, Pedro de Seda, and Pedro Henríquez, Santo Domingo's former Lieutenant-Governor (top administrator), José Núñez de Cáceres , declared the colony's independence from
15747-548: The Haitian coasts, plundered seaside villages, as far as Dame Marie , and butchered crews of captured enemy ships. A fourth and final invasion by Haiti in November 1855 was defeated by Dominican forces by January 27, 1856, resulting in thousands of Haitian casualties. Again Santana and Báez plotted against each other for political dominance, with Báez winning the first encounter and expelling Santana in 1857, and Santana winning
15928-709: The Haitian-Dominican border under the orders of Trujillo. During World War II , Trujillo symbolically sided with the Allies and declared war on Japan the day after the attack on Pearl Harbor and on Nazi Germany and Italy four days later. Soon after, German U-boats torpedoed and sank two Dominican merchant vessels—the San Rafael off Jamaica and the Presidente Trujillo off Fort-de-France . German U-boats also sank four Dominican-manned ships in
16109-719: The Haitians. By April 15, Dominican forces had defeated the Haitian forces on both land and sea. In early July 1844, Duarte was urged by his followers to take the title of President of the Republic. Duarte agreed, but only if free elections were arranged. However, Santana's forces took Santo Domingo on July 12, and they declared Santana ruler of the Dominican Republic. Santana then put Mella, Duarte, and Sánchez in jail. On February 27, 1845, Santana executed María Trinidad Sánchez , heroine of La Trinitaria, and others for conspiracy. In August of that year, Haiti made another attempt to conquer
16290-457: The NHC began to monitor a tropical wave over the central tropical Atlantic for gradual development, though environmental conditions for development were assessed as only marginally favorable. Even so, shower and thunderstorm activity within the disturbance began to become more concentrated later that same day, then increased and became better organized during the next day. The circulation associated with
16471-632: The PDI is similar in nature to ACE, with the major difference being that wind speeds are cubed rather than squared. The Hurricane Surge Index is a metric of the potential damage a storm may inflict via storm surge. It is calculated by squaring the dividend of the storm's wind speed and a climatological value (33 m/s or 74 mph), and then multiplying that quantity by the dividend of the radius of hurricane-force winds and its climatological value (96.6 km or 60.0 mi). This can be represented in equation form as: where v {\textstyle v}
16652-666: The PRD's Hipólito Mejía won the election. This was a time of economic troubles. Under Mejía, the Dominican Republic participated in the US-led coalition, as part of the Multinational Plus Ultra Brigade , during the 2003 invasion of Iraq , suffering no casualties. In 2008, Fernández was elected for a third term. Fernández and the PLD are credited with initiatives that have moved the country forward technologically, on
16833-644: The San Juan Valley is provided by the San Juan River, tributary of the Yaque del Sur , which empties into the Caribbean, in the south. The Artibonito is the longest river of Hispaniola and flows westward into Haiti. There are many lakes and coastal lagoons. The largest lake is Enriquillo , a salt lake at 45 metres (148 ft) below sea level, the lowest elevation in the Caribbean. There are many small offshore islands and cays that form part of
17014-463: The South Atlantic is not a major basin, and not an official basin according to the WMO. Each year on average, around 80 to 90 named tropical cyclones form around the world, of which over half develop hurricane-force winds of 65 kn (120 km/h; 75 mph) or more. Worldwide, tropical cyclone activity peaks in late summer, when the difference between temperatures aloft and sea surface temperatures
17195-547: The Spanish forces. The Haitian rebel Sylvain Salnave , fearful of the reestablishment of Spain as colonial power, gave refuge and logistics to revolutionaries seeking to reestablish the independent nation. The ensuing civil war, known as the War of Restoration , killed more than 50,000. The war began on August 16, 1863. The Spanish garrison of Santiago was forced to retreat to Puerto Plata by mid-September. The Dominicans bombarded
17376-499: The Trujillos attempted to "reassert dictatorial domination". Following this warning, and the arrival of a 14-vessel U.S. naval task force within sight of Santo Domingo, Ramfis and his uncles fled the country on November 19. The OAS lifted its sanctions on January 4, 1962. In February 1963, a democratically elected government under leftist Juan Bosch took office but it was overthrown by a military coup in September. On April 24, 1965,
17557-427: The U.S. occupation of 1916–24, peasants from the countryside, called Gavilleros, would not only kill U.S. Marines, but would also attack and kill Arab vendors traveling through the countryside. From 1902 on, short-lived governments were again the norm, with their power usurped by caudillos in parts of the country. Furthermore, the national government was bankrupt and, unable to pay its debts to European creditors, faced
17738-610: The United States National Hurricane Center and Fiji Meteorological Service issue alerts, watches and warnings for various island nations in their areas of responsibility. The United States Joint Typhoon Warning Center and Fleet Weather Center also publicly issue warnings about tropical cyclones on behalf of the United States Government . The Brazilian Navy Hydrographic Center names South Atlantic tropical cyclones , however
17919-519: The Western Pacific. Tropical cyclones have to have a significant amount of gale-force winds occurring around the center before they are named within the Southern Hemisphere . The names of significant tropical cyclones in the North Atlantic Ocean, Pacific Ocean, and Australian region are retired from the naming lists and replaced with another name. Tropical cyclones that develop around the world are assigned an identification code consisting of
18100-475: The adjectival form of "Domingo", and as such, the revolutionaries named their newly independent country the "Dominican Republic" ( la República Dominicana ). In the national anthem of the Dominican Republic ( himno nacional de la República Dominicana ), the poetic term "Quisqueyans" ( Quisqueyanos ) is used instead of "Dominicans". The word "Quisqueya" derives from the Taíno language , and means "mother of
18281-435: The aftermath of the storm. El Yunque National Forest partially re-opened from the storm on October 12. A few days after the hurricane, New York City mayor Eric Adams visited the Dominican Republic and Puerto Rico . After the visit, he requested a $ 3.7 billion supplemental bill for emergency and nutritional aid. Due to the severe damage and number of deaths the hurricane caused across the Caribbean and in eastern Canada,
18462-486: The assassinations of political opposition, the massacre of Haitians , and Trujillo's plots against other countries. The U.S. finally broke with Trujillo in 1960, after Trujillo's agents attempted to assassinate the Venezuelan president, Rómulo Betancourt , with a car bomb, as he was a fierce critic of Trujillo. After its representatives confirmed Trujillo's complicity in the nearly successful assassination attempt,
18643-491: The attack for $ 1 million, but Castro learned of the plot and instructed Morgan to go along with it and report back. Trujillo was tricked into believing that Morgan had captured Trinidad . On August 13, 1959, a C-47 transport flying from the Dominican Republic carrying military advisors and supplies landed at Trinidad airport. Castro seized the aircraft and the ten occupants and arrested some 4,000 suspects throughout Cuba. On November 25, 1960, Trujillo's henchmen killed three of
18824-629: The center of Fiona made landfall with estimated winds of 100 mph (160 km/h) on the Canso Peninsula , Nova Scotia , near Whitehead ; based on observations from a nearby weather station at Hart Island and the East Chedabucto Bay buoy , the central pressure at the time was estimated to have been 931 mbar (27.5 inHg), the lowest measured on record in association with a landfalling post-tropical cyclone in Canada, and
19005-501: The city on July 5, coinciding with General Arias' surrender to the Dominican governor. The military government established by the U.S. under the Navy and Marine Corps on November 29, led by Vice Admiral Harry Shepard Knapp , was widely repudiated by the Dominicans, but organized resistance ceased. The occupation regime kept most Dominican laws and institutions and largely pacified the general population. The occupying government also revived
19186-642: The coast of eastern Northern America outside of the United States Gulf Coast states. Other weather stations also documented pressures below the previous record of 940.2 mbar (27.76 inHg). A peak wind gust of 111 mph (179 km/h) was recorded in Arisaig, Nova Scotia . Peak gusts in other Canadian provinces included 110 mph (180 km/h) at Wreckhouse, Newfoundland and Labrador , 93 mph (150 km/h) at East Point, Prince Edward Island , 78 mph (126 km/h) on
19367-410: The country against Medina's government), marking the end to 16 years in power of the centre-left Dominican Liberation Party (PLD). In May 2024, President Luis Abinader won a second term in elections . Especially his tough policies towards migration from neighbouring Haiti was popular among voters. The Dominican Republic comprises the eastern five-eighths of Hispaniola , the second-largest island in
19548-538: The country for over a year and left after supervising elections in 1966 won by Joaquín Balaguer . He had been Trujillo's last puppet-president. Balaguer remained in power as president for 12 years. His tenure was a period of repression of human rights and civil liberties. His rule was criticized for a growing disparity between rich and poor. It was, however, praised for an ambitious infrastructure program, which included construction of large housing projects, sports complexes, theaters, museums, aqueducts, roads, highways, and
19729-403: The country's major export. This action ultimately cost the Dominican Republic almost $ 22,000,000 in lost revenues at a time when its economy was in a rapid decline. Trujillo had become expendable, and dissidents inside the Dominican Republic argued that assassination was the only certain way to remove him. On May 30, 1961, Trujillo was shot and killed by Dominican dissidents. Ramfis Trujillo ,
19910-435: The development of the westerlies . Cyclone formation is usually reduced 3 days prior to the wave's crest and increased during the 3 days after. The majority of tropical cyclones each year form in one of seven tropical cyclone basins, which are monitored by a variety of meteorological services and warning centers. Ten of these warning centers worldwide are designated as either a Regional Specialized Meteorological Centre or
20091-456: The dictator's son, remained in de facto control of the government for the next 6 months, as commander of the armed forces. Trujillo's brothers, Hector Bienvenido and Jose Arismendi Trujillo, returned to the country and plotted against President Balaguer. On November 18, 1961, as a planned coup became more evident, U.S. Secretary of State Dean Rusk issued a warning that the US would not "remain idle" if
20272-483: The eastern Caribbean. Early on September 18, the storm strengthened into a hurricane as it approached Puerto Rico . A few hours later, the eye of Fiona made landfall along the southwestern coast of Puerto Rico near Punta Tocon between the municipalities of Lajas and Cabo Rojo at 19:20 UTC on September 18, with maximum sustained winds of 85 miles per hour (135 km/h) and a minimum central pressure of 986 mbar (29.12 inHg). The storm emerged over
20453-461: The entire island was either Ayiti or Quisqueya . Christopher Columbus arrived on the island on December 5, 1492, during the first of his four voyages to the Americas. He claimed the land for Spain and named it La Española , due to its diverse climate and terrain, which reminded him of the Spanish landscape. In 1496, Bartholomew Columbus , Christopher's brother, built the city of Santo Domingo , Western Europe's first permanent settlement in
20634-793: The entrainment of dry air into the cyclone. The heaviest rains fell in eastern Nova Scotia, where totals generally ranged between 100–200 mm (3.9–7.9 in). Fiona affected the four provinces of Atlantic Canada , as well as Quebec. The storm caused major flooding in Quebec's Magdalen Islands , southeastern New Brunswick, Prince Edward Island, northeastern Nova Scotia, and southern Newfoundland. Thousands of trees were knocked down and uprooted in Nova Scotia from Halifax eastward, as well as most of southeastern New Brunswick, most of P.E.I., and some parts in Newfoundland. Wind gusts of 179 km/h (111 mph) were reported in Arisaig, Nova Scotia with
20815-492: The equator, then move poleward past the ridge axis before recurving into the main belt of the Westerlies . When the subtropical ridge position shifts due to El Niño, so will the preferred tropical cyclone tracks. Areas west of Japan and Korea tend to experience much fewer September–November tropical cyclone impacts during El Niño and neutral years. During La Niña years, the formation of tropical cyclones, along with
20996-469: The evaporation of water from the ocean surface, which ultimately condenses into clouds and rain when moist air rises and cools to saturation . This energy source differs from that of mid-latitude cyclonic storms , such as nor'easters and European windstorms , which are powered primarily by horizontal temperature contrasts . Tropical cyclones are typically between 100 and 2,000 km (62 and 1,243 mi) in diameter. The strong rotating winds of
21177-407: The eye of Fiona made landfall along the southwestern coast of Puerto Rico, near Punta Tocon, between the municipalities of Lajas and Cabo Rojo . The hurricane made landfall in the Dominican Republic shortly thereafter, and then strengthened into the first major hurricane of the season. As the storm slowly moved through the Turks and Caicos , it continued to strengthen and reached Category 4 status
21358-481: The eyewall of the storm, and an upper-level anticyclone helps channel this air away from the cyclone efficiently. However, some cyclones such as Hurricane Epsilon have rapidly intensified despite relatively unfavorable conditions. There are a number of ways a tropical cyclone can weaken, dissipate, or lose its tropical characteristics. These include making landfall, moving over cooler water, encountering dry air, or interacting with other weather systems; however, once
21539-811: The farming areas of the nation. Rather less productive are the semi-arid San Juan Valley, south of the Central Cordillera, and the Neiba Valley, tucked between the Sierra de Neiba and the Sierra de Bahoruco. Much of the land around the Enriquillo Basin is below sea level, with a hot, arid, desert-like environment. There are other smaller valleys in the mountains, such as the Constanza , Jarabacoa , Villa Altagracia , and Bonao valleys. The Llano Costero del Caribe ("Caribbean Coastal Plain")
21720-489: The following day, while accelerating north. The storm reached peak 1-minute sustained winds of 140 mph (220 km/h) and a minimum pressure of 931 mbar (27.49 inHg). After passing Bermuda and weakening to Category 3 intensity, Fiona quickly transitioned into a large and powerful extratropical cyclone and struck Nova Scotia with sustained winds of 100 mph (155 km/h) early on September 24. Post-tropical Fiona then quickly weakened as it moved through
21901-410: The form of cold water from falling raindrops (this is because the atmosphere is cooler at higher altitudes). Cloud cover may also play a role in cooling the ocean, by shielding the ocean surface from direct sunlight before and slightly after the storm passage. All these effects can combine to produce a dramatic drop in sea surface temperature over a large area in just a few days. Conversely, the mixing of
22082-522: The four Mirabal sisters , nicknamed Las Mariposas (The Butterflies). Along with their husbands, the sisters were conspiring to overthrow Trujillo in a violent revolt. The International Day for the Elimination of Violence against Women is observed on the anniversary of their deaths. For a long time, the U.S. and the Dominican elite supported the Trujillo government. This support persisted despite
22263-483: The four highest peaks in the Caribbean: Pico Duarte (3,098 metres or 10,164 feet above sea level), La Pelona (3,094 metres or 10,151 feet), La Rucilla (3,049 metres or 10,003 feet), and Pico Yaque (2,760 metres or 9,055 feet). In the southwest corner of the country, south of the Cordillera Central, there are two other ranges: the more northerly of the two is the Sierra de Neiba , while in the south
22444-453: The frequency of very intense storms and a poleward extension of where the cyclones reach maximum intensity are among the possible consequences of human-induced climate change. Tropical cyclones use warm, moist air as their fuel. As climate change is warming ocean temperatures , there is potentially more of this fuel available. Between 1979 and 2017, there was a global increase in the proportion of tropical cyclones of Category 3 and higher on
22625-532: The general public regarding forecasts, watches, and warnings. Since the systems can last a week or longer, and more than one can be occurring in the same basin at the same time, the names are thought to reduce the confusion about what storm is being described. Names are assigned in order from predetermined lists with one, three, or ten-minute sustained wind speeds of more than 65 km/h (40 mph) depending on which basin it originates. Standards vary from basin to basin. Some tropical depressions are named in
22806-582: The highest in the Western Hemisphere. Recent growth has been driven by construction, manufacturing, tourism, and mining. The country is the site of the third largest (in terms of production) gold mine in the world, the Pueblo Viejo mine . The Dominican Republic is the most visited destination in the Caribbean. A geographically diverse nation, the Dominican Republic is home to both the Caribbean's tallest mountain peak, Pico Duarte , and
22987-481: The hurricane struck, a delegation from United Hatzalah of Israel arrived to provide psychological and emotional stabilization to those affected by the storm in various sections of the island. Working together with local community leaders and organizations including PR4PR , Chabad , and FREMS , the team assisted hundreds of people in the municipalities of Anasco and Loiza providing them with basic medical check ups, and psychological first aid tools to help them cope with
23168-406: The hurricane. The eye of Hurricane Fiona made landfall along the coast of the Dominican Republic near Boca de Yuma at 07:30 UTC on September 19. It was the first hurricane to make landfall in the country in 18 years. President Luis Abinader declared state of emergency in five southeastern provinces and three northeastern provinces and visited La Altagracia , El Seibo and Hato Mayor —
23349-451: The intensity from leveling off before an eye emerges in infrared imagery. The SATCON weights estimates from various satellite-based systems and microwave sounders , accounting for the strengths and flaws in each individual estimate, to produce a consensus estimate of a tropical cyclone's intensity which can be more reliable than the Dvorak technique at times. Multiple intensity metrics are used, including accumulated cyclone energy (ACE),
23530-522: The intensity of a tropical cyclone. Reconnaissance aircraft fly around and through tropical cyclones, outfitted with specialized instruments, to collect information that can be used to ascertain the winds and pressure of a system. Tropical cyclones possess winds of different speeds at different heights. Winds recorded at flight level can be converted to find the wind speeds at the surface. Surface observations, such as ship reports, land stations, mesonets , coastal stations, and buoys, can provide information on
23711-533: The island. Many crops were destroyed, and agriculture secretary Ramón González Beiró forecast a roughly $ 100 million loss this year. U.S. President Joe Biden declared a state of emergency over the storm on September 18, 2022, and all flights to and from Luis Muñoz Marín International Airport were canceled. On the same day, the effects of Fiona's massive rainfall cut off all of the power in Puerto Rico . At least 21 deaths in Puerto Rico have been attributed to
23892-463: The killing of all police officers. On April 28, U.S. President Lyndon Johnson deployed U.S. Marines to Santo Domingo to protect American citizens, with U.S. forces subsequently expanded to 24,000 troops. On April 30, two battalions of the 82nd Airborne Division landed at San Isidro airfield . Hours later, U.S. troops crossed the Duarte Bridge to link up with Loyalists, who were to secure
24073-459: The lands". It is often used in songs as another name for the country. The name of the country in English is often shortened to "the D.R." ( la R.D. ), but this is rare in Spanish. The islands of the Caribbean were first settled around 6,000 years ago by hunter-gatherer peoples originating from Central America or northern South America. The Arawakan-speaking ancestors of the Taíno moved into
24254-693: The late 1800s and early 1900s and gradually superseded the existing system—simply naming cyclones based on what they hit. The system currently used provides positive identification of severe weather systems in a brief form, that is readily understood and recognized by the public. The credit for the first usage of personal names for weather systems is generally given to the Queensland Government Meteorologist Clement Wragge who named systems between 1887 and 1907. This system of naming weather systems fell into disuse for several years after Wragge retired, until it
24435-404: The main belt of the Westerlies , by means of merging with a nearby frontal zone, can cause tropical cyclones to evolve into extratropical cyclones . This transition can take 1–3 days. Should a tropical cyclone make landfall or pass over an island, its circulation could start to break down, especially if it encounters mountainous terrain. When a system makes landfall on a large landmass, it
24616-615: The massive Columbus Lighthouse , completed in 1992 during a later tenure. In 1978, Balaguer was succeeded to the presidency by opposition candidate Antonio Guzmán Fernández , of the Dominican Revolutionary Party (PRD). Hurricane David hit the Dominican Republic in August 1979, which left upwards of 2,000 people dead and 200,000 homeless. The hurricane caused over $ 1 billion in damage. Another PRD win in 1982 followed, under Salvador Jorge Blanco . Balaguer regained
24797-434: The most damaged provinces — on September 20, 2022. Over one million people were left without running water and another 350,000 in the country were left without electricity in the country after Fiona had passed. Widespread rainfall totals of 8–16 inches (200–410 mm) drenched the country. At least 2 people were killed and over 8,300 homes were destroyed in the Dominican Republic. President Abinader stated that damage from
24978-514: The neighboring French colony of Saint-Domingue —the wealthiest colony in the Caribbean and whose population of half a million was 90% enslaved and four times as numerous as Santo Domingo. In 1795, Spain ceded Santo Domingo to France by the Treaty of Basel as a result of its defeat in the War of the Pyrenees . Saint-Domingue achieved independence as Haiti from France on January 1, 1804. In 1809,
25159-660: The northern coast and in the Pedernales Peninsula. Four major rivers drain the numerous mountains of the Dominican Republic. The Yaque del Norte is the longest and most important Dominican river. It carries excess water down from the Cibao Valley and empties into Monte Cristi Bay, in the northwest. Likewise, the Yuna River serves the Vega Real and empties into Samaná Bay, in the northeast. Drainage of
25340-522: The observed trend of rapid intensification of tropical cyclones in the Atlantic basin. Rapidly intensifying cyclones are hard to forecast and therefore pose additional risk to coastal communities. Warmer air can hold more water vapor: the theoretical maximum water vapor content is given by the Clausius–Clapeyron relation , which yields ≈7% increase in water vapor in the atmosphere per 1 °C (1.8 °F) warming. All models that were assessed in
25521-424: The other hand, his administrations have been accused of corruption. Danilo Medina of the PLD was elected president in 2012 and re-elected in 2016. On the other hand, a significant increase in crime, government corruption and a weak justice system threaten to overshadow their administrative period. He was succeeded by the opposition candidate Luis Abinader in the 2020 election (weeks after protests erupted in
25702-466: The overall frequency of tropical cyclones worldwide, with increased frequency in the North Atlantic and central Pacific, and significant decreases in the southern Indian Ocean and western North Pacific. There has been a poleward expansion of the latitude at which the maximum intensity of tropical cyclones occurs, which may be associated with climate change. In the North Pacific, there may also have been an eastward expansion. Between 1949 and 2016, there
25883-649: The patron saint of astronomers , and founder of the Dominican Order . The Dominican Order established what is now known as the Universidad Autónoma de Santo Domingo , the first university in the New World. For most of its history, up until independence, the colony was known simply as Santo Domingo and continued to be commonly known as such in English until the early 20th century. The residents were called "Dominicans" ( Dominicanos ),
26064-538: The population of Taínos had declined drastically due to smallpox , measles, and other diseases that arrived with the Europeans. African slaves were imported to replace the dwindling Taínos. The last record of pure Taínos in the country was from 1864. Still, Taíno biological heritage survived due to intermixing. Census records from 1514 reveal that 40% of Spanish men in Santo Domingo were married to Taíno women, and some present-day Dominicans have Taíno ancestry. By
26245-429: The port of Puerto Plata and destroyed much of the town. In the south, Spanish forces were successful in driving the rebels out of several towns and into Haiti. However, the capture of Azua proved to be a costly endeavor, with two months of fighting and a significant loss of lives for the Spanish. Spanish forces from Cuba attacked and captured Monte Cristi on the north coast, but sustained heavy casualties. By 1865,
26426-440: The potential of spawning tornadoes . Climate change affects tropical cyclones in several ways. Scientists found that climate change can exacerbate the impact of tropical cyclones by increasing their duration, occurrence, and intensity due to the warming of ocean waters and intensification of the water cycle . Tropical cyclones draw in air from a large area and concentrate the water content of that air into precipitation over
26607-413: The presence of moderate or strong wind shear depending on the evolution and structure of the storm's convection. The size of tropical cyclones plays a role in how quickly they intensify. Smaller tropical cyclones are more prone to rapid intensification than larger ones. The Fujiwhara effect , which involves interaction between two tropical cyclones, can weaken and ultimately result in the dissipation of
26788-422: The presidency in 1986 and was re-elected in 1990 and 1994, in the latter defeating PRD candidate José Francisco Peña Gómez , a former mayor of Santo Domingo. The 1994 elections were flawed, bringing international pressure, to which Balaguer responded by scheduling another presidential contest in 1996. Balaguer was not a candidate. The PSRC candidate was his Vice President Jacinto Peynado Garrigosa . In 1996, with
26969-416: The proceeds for his personal use and to maintain his police state. In 1899, he was assassinated. However, the relative calm over which he presided allowed improvement in the Dominican economy. The sugar industry was modernized, and the country attracted foreign workers and immigrants. Lebanese, Syrians, Turks, and Palestinians began to arrive in the country during the latter part of the 19th century. During
27150-609: The province's dune system, particularly within Prince Edward Island National Park . On September 25, Deputy Premier of Quebec Geneviève Guilbault flew to the Magdalen Islands to view the storm damage. Insured losses from Fiona in Canada are estimated to be at least CA$ 800 million (US$ 590 million), with the total damage expected to be significantly higher. This became the costliest weather event in Atlantic Canada history, and
27331-444: The release of latent heat from the saturated soil. Orographic lift can cause a significant increase in the intensity of the convection of a tropical cyclone when its eye moves over a mountain, breaking the capped boundary layer that had been restraining it. Jet streams can both enhance and inhibit tropical cyclone intensity by influencing the storm's outflow as well as vertical wind shear. On occasion, tropical cyclones may undergo
27512-492: The same intensity. The passage of a tropical cyclone over the ocean causes the upper layers of the ocean to cool substantially, a process known as upwelling , which can negatively influence subsequent cyclone development. This cooling is primarily caused by wind-driven mixing of cold water from deeper in the ocean with the warm surface waters. This effect results in a negative feedback process that can inhibit further development or lead to weakening. Additional cooling may come in
27693-492: The same system. The ASCAT is a scatterometer used by the MetOp satellites to map the wind field vectors of tropical cyclones. The SMAP uses an L-band radiometer channel to determine the wind speeds of tropical cyclones at the ocean surface, and has been shown to be reliable at higher intensities and under heavy rainfall conditions, unlike scatterometer-based and other radiometer-based instruments. The Dvorak technique plays
27874-513: The sea can result in heat being inserted in deeper waters, with potential effects on global climate . Vertical wind shear decreases tropical cyclone predicability, with storms exhibiting wide range of responses in the presence of shear. Wind shear often negatively affects tropical cyclone intensification by displacing moisture and heat from a system's center. Low levels of vertical wind shear are most optimal for strengthening, while stronger wind shear induces weakening. Dry air entraining into
28055-539: The second and expelling Báez in 1859. In 1861, after imprisoning, exiling, and executing many of his opponents and due to political and economic reasons, Santana asked Queen Isabella II of Spain to retake control of the Dominican Republic. Spain, which had not come to terms with the loss of its mainland American colonies 40 years earlier, made the country a colony again. The island was occupied by 30,000 Spanish troops bolstered by battalions of Cuban and Puerto Rican volunteers and 12,000 Dominicans who aligned themselves with
28236-801: The seventh-costliest nationwide (adjusted for inflation). At least 670 people were rescued from impacted sites following Fiona's deluge. U.S. President Joe Biden approved a disaster declaration for the island, allowing funding for search and rescue, debris removal, and shelter and food among other accommodations for a month. Damage and debris left from Fiona disallowed rescuers and officials from entering affected areas. By September 22, 470 people and 48 pets remained in shelters. Biden's disaster declaration also allowed FEMA to assist survivors in 55 municipalities and for public assistance in all 78 of them. 7 million liters of water, 4 million ready-to-eat meals, more than 215 generators, 100,000 tarps, and more were provided in four warehouses around Puerto Rico. A few days after
28417-577: The storm exceeded 20 billion pesos (US$ 375 million). Fiona's eye passed through the Grand Turks island , severely affecting the telecommunications in the archipelago. At least 40% of the territory was left without electricity, with total blackouts reported in North Caicos , Middle Caicos , South Caicos , Grand Turk and Salt Cay . 30% of Providenciales experienced power outages. Moderate damage and no deaths were reported. During
28598-553: The storm was also the most intense Category 4 Atlantic hurricane on record at such a northerly latitude. Six hours later, as it began interact with a mid- to upper-level trough, Fiona began to slowly weaken again and accelerated to the north-northeast at 40 miles per hour (64 km/h), and subsequently became a post-tropical cyclone as it became embedded within the larger-scale trough while still maintaining major hurricane-force winds of 115 mph (185 km/h). Steady weakening continued and by 07:00 UTC on September 24,
28779-617: The subtropical ridge position, shifts westward across the western Pacific Ocean, which increases the landfall threat to China and much greater intensity in the Philippines . The Atlantic Ocean experiences depressed activity due to increased vertical wind shear across the region during El Niño years. Tropical cyclones are further influenced by the Atlantic Meridional Mode , the Quasi-biennial oscillation and
28960-643: The support of Joaquín Balaguer and the Social Christian Reform Party in a coalition called the Patriotic Front, Leonel Fernández achieved the first-ever win for the Dominican Liberation Party (PLD), which Bosch had founded in 1973 after leaving the PRD. Fernández oversaw a fast-growing economy: growth averaged 7.7% per year, unemployment fell, and there were stable exchange and inflation rates. In 2000,
29141-419: The surface pressure decreases by 2.5 hPa (0.074 inHg) per hour for at least 12 hours or 5 hPa (0.15 inHg) per hour for at least 6 hours. For rapid intensification to occur, several conditions must be in place. Water temperatures must be extremely high, near or above 30 °C (86 °F), and water of this temperature must be sufficiently deep such that waves do not upwell cooler waters to
29322-483: The surface. On the other hand, Tropical Cyclone Heat Potential is one of such non-conventional subsurface oceanographic parameters influencing the cyclone intensity. Wind shear must be low. When wind shear is high, the convection and circulation in the cyclone will be disrupted. Usually, an anticyclone in the upper layers of the troposphere above the storm must be present as well—for extremely low surface pressures to develop, air must be rising very rapidly in
29503-648: The system and its intensity. For example, within the Northern Atlantic and Eastern Pacific basins, a tropical cyclone with wind speeds of over 65 kn (120 km/h; 75 mph) is called a hurricane , while it is called a typhoon or a severe cyclonic storm within the Western Pacific or North Indian oceans. When a hurricane passes west across the International Dateline in the Northern Hemisphere, it becomes known as
29684-540: The system became more defined and persisted overnight and into the morning of September 14, attaining sufficient organization to designated as Tropical Depression Seven later that day. Despite the continued effects of moderate westerly shear and dry mid-level air flow, new satellite imagery indicated the depression had strengthened, thus at 01:45 UTC on September 15, it became Tropical Storm Fiona. The storm passed over Guadeloupe with 50 mph (45 kn; 80 km/h) winds on September 16, as it entered
29865-478: The territory's population was left without water, and at least 25 people died. In the Dominican Republic and the Turks and Caicos, the islands were pounded by heavy rainfall and strong winds, causing flooding and blackouts. Fiona was the strongest cyclone on record to make landfall in Canada based on atmospheric pressure and was one of the wettest ever recorded in the country as well. Early on September 12, 2022,
30046-519: The threat of military intervention by France, Germany , and Italy . United States President Theodore Roosevelt sought to prevent European intervention, largely to protect the routes to the future Panama Canal . He made a small military intervention to ward off European powers, to proclaim his famous Roosevelt Corollary to the Monroe Doctrine , and also to obtain his 1905 Dominican agreement for U.S. administration of Dominican customs, which
30227-458: The time of the Treaty of Ryswick in 1697, which ceded the western one-third of the island to France, the population of Santo Domingo consisted of a few thousand whites, approximately 30,000 black slaves, and a few Taínos. By 1789, the population had grown to 125,000, but Santo Domingo remained one of Spain's less wealthy and strategically important colonies in the New World. The population composition of Santo Domingo sharply contrasted with that of
30408-411: The time, both ruling arbitrarily. They promoted competing plans to annex the new nation to a major power. The Dominican Republic's first constitution was adopted on November 6, 1844, and its population in 1845 was approximately 230,000 people (100,000 whites; 40,000 blacks; and 90,000 mulattoes). In March 1844, Haiti invaded, but the Dominicans put up stiff opposition and inflicted heavy casualties on
30589-423: The tropical cyclone year begins on July 1 and runs all year-round encompassing the tropical cyclone seasons, which run from November 1 until the end of April, with peaks in mid-February to early March. Of various modes of variability in the climate system, El Niño–Southern Oscillation has the largest effect on tropical cyclone activity. Most tropical cyclones form on the side of the subtropical ridge closer to
30770-451: The weaker of two tropical cyclones by reducing the organization of the system's convection and imparting horizontal wind shear. Tropical cyclones typically weaken while situated over a landmass because conditions are often unfavorable as a result of the lack of oceanic forcing. The Brown ocean effect can allow a tropical cyclone to maintain or increase its intensity following landfall , in cases where there has been copious rainfall, through
30951-413: The western third of the island, which became the independent First Empire of Haiti in 1804. A group of Dominicans deposed the Spanish governor and declared independence from Spain in November 1821, but were annexed by Haiti in February 1822. Independence came 22 years later in 1844, after victory in the Dominican War of Independence . The next 72 years saw several civil wars, failed invasions by Haiti, and
31132-402: The wind speed of Hurricane Helene by 11%, it increased the destruction from it by more than twice. According to World Weather Attribution the influence of climate change on the rainfall of some latest hurricanes can be described as follows: Tropical cyclone intensity is based on wind speeds and pressure. Relationships between winds and pressure are often used in determining the intensity of
31313-659: Was 185 kn (95 m/s; 345 km/h; 215 mph) in Hurricane Patricia in 2015—the most intense cyclone ever recorded in the Western Hemisphere . Warm sea surface temperatures are required for tropical cyclones to form and strengthen. The commonly-accepted minimum temperature range for this to occur is 26–27 °C (79–81 °F), however, multiple studies have proposed a lower minimum of 25.5 °C (77.9 °F). Higher sea surface temperatures result in faster intensification rates and sometimes even rapid intensification . High ocean heat content , also known as Tropical Cyclone Heat Potential , allows storms to achieve
31494-475: Was a slowdown in tropical cyclone translation speeds. It is unclear still to what extent this can be attributed to climate change: climate models do not all show this feature. A 2021 study review article concluded that the geographic range of tropical cyclones will probably expand poleward in response to climate warming of the Hadley circulation . When hurricane winds speed rise by 5%, its destructive power rise by about 50%. Therfore, as climate change increased
31675-770: Was centered about 80 miles (130 km) northwest of Port aux Basques , Newfoundland , and had maximum sustained winds of 70 mph (110 km/h). Fiona would continue to weaken as it moved erratically northward into the northwestern Atlantic before dissipating west of Greenland over Baffin Bay on September 27. After the naming of Fiona, tropical storm watches were issued for the islands of Saba , St. Eustatius , St. Maarten , Antigua and Barbuda , St. Kitts and Nevis , Montserrat , and Anguilla . These were raised to tropical storm warnings two advisories later with watches extended south to Guadeloupe , St. Barthelemy , and St. Martin . As Fiona moved west, tropical storm watches then warnings were put in place for Puerto Rico and
31856-516: Was declared on September 19. Roads were stripped of pavement due to Fiona's torrential rainfall, roofs were torn off houses, and at least one bridge was completely washed away. A million people, about 33% of the population, were left without drinking water. Two days after the storm, less than 10% of customers had their power restored. A gauge near Ponce measured 31.34 inches (796.0 mm) inches of rain, while winds gusted to as high as 113 mph (182 km/h). Many landslides were recorded throughout
32037-454: Was indicated by satellite data and reports from a buoy over Banquereau Bank where waves averaged 12 to 15 m (39 to 49 ft) with peak waves as high as 30 m (98 ft). Fiona then moved over Cape Breton Island with hurricane-strength winds and hit Prince Edward Island . It continued to weaken as it moved northward into the Gulf of St. Lawrence . When the NHC issued its final advisory on Fiona at 21:00 UTC that same day, it
32218-466: Was killed when her home was destroyed and she was swept into the ocean; another person died of carbon monoxide poisoning while operating an electrical generator in Prince Edward Island. Another man in Lower Prospect, Nova Scotia was swept out to sea and presumed dead. Teacup Rock, a rock formation and local tourist attraction on the coast near Thunder Cove, Prince Edward Island , was destroyed after Hurricane Fiona struck. Fiona also caused severe erosion to
32399-474: Was revived in the latter part of World War II for the Western Pacific. Formal naming schemes have subsequently been introduced for the North and South Atlantic, Eastern, Central, Western and Southern Pacific basins as well as the Australian region and Indian Ocean. At present, tropical cyclones are officially named by one of twelve meteorological services and retain their names throughout their lifetimes to provide ease of communication between forecasters and
32580-584: Was several years of great political instability and civil war . U.S. mediation by the William Howard Taft and Woodrow Wilson administrations achieved only a short respite each time. A political deadlock in 1914 was broken after an ultimatum by Wilson telling the Dominicans to choose a president or see the U.S. impose one. A provisional president was chosen, and later the same year relatively free elections put former president (1899–1902) Juan Isidro Jimenes Pereyra back in power. With his former Secretary of War Desiderio Arias maneuvering to depose him and despite
32761-422: Was the chief source of income for the Dominican government. A 1906 agreement provided for the arrangement to last 50 years. The United States agreed to use part of the customs proceeds to reduce the immense foreign debt of the Dominican Republic and assumed responsibility for said debt. After six years in power, President Ramón Cáceres (who had himself assassinated Heureaux) was assassinated in 1911. The result
