155-607: Effects Other wikis Hurricane Jeanne was the deadliest tropical cyclone in the Atlantic basin since Mitch in 1998 , and the deadliest tropical cyclone worldwide in 2004 . It was the tenth named storm, the seventh hurricane, and the fifth major hurricane of the season, as well as the third hurricane and fourth named storm of the season to make landfall in Florida . After wreaking havoc on Hispaniola , Jeanne struggled to reorganize, eventually strengthening and performing

310-531: A Tropical Cyclone Warning Centre by the World Meteorological Organization 's (WMO) tropical cyclone programme. 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

465-679: A humid subtropical climate ( Cfa ) and average temperatures in Dade City range from 59.2 °F in January to 82.1 °F in July and August while in Port Richey they range from 59.0 °F in January to 82.2 °F in August. PRISM Climate Group at Oregon State University As of the 2020 United States census , there were 561,891 people, 209,483 households, and 139,278 families residing in

620-416: 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

775-444: 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

930-598: A 24‑hour period, surpassing a 1 in 100 year event. Heavy rainfall also fell on the offshore island of Culebra . The heavy rainfall caused severe flooding along many rivers of Puerto Rico, forcing 3,629 people to evacuate their houses in flood zones. The one and only flood-related death occurred when a person drowned in the Culebrinas River in Moca . Across the island, Jeanne produced mudslides and landslides and left $ 8 million in damage (2004  USD ) to

1085-613: A circle, whirling round their central clear eye , with their surface winds blowing counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere . The opposite direction of circulation is due to the Coriolis effect . Tropical cyclones tend to develop during the summer, but have been noted in nearly every month in most tropical cyclone basins . Tropical cyclones on either side of

1240-714: A complete loop in the process) before beginning a steady westward motion toward the Bahamas and Florida . Jeanne continued strengthening as it headed west, passing over Great Abaco in the Bahamas on the morning of September 25. Shortly thereafter, the hurricane reached Category 3 strength. Jeanne maintained this intensity as it passed Grand Bahama Island. At 11:50 p.m. EDT on September 25 (0350 UTC September 26), Jeanne made landfall on Hutchinson Island , just east of Sewall's Point, Florida ; Stuart, Florida ; and Port Saint Lucie, Florida , at Category 3 strength. This

1395-595: A complete loop over the open Atlantic. It headed westwards, strengthening into a Category 3 hurricane and passing over the islands of Great Abaco and Grand Bahama in the Bahamas on September 25. Jeanne made landfall later in the day in Florida just two miles (three kilometers) from where Hurricane Frances had struck a mere three weeks earlier. Building on the rainfall of Frances and Hurricane Ivan , Jeanne brought near-record flood levels as far north as West Virginia and New Jersey before its remnants turned east into

1550-399: A development in 1941. West Pasco includes retirement areas, commercial fishing, and suburbs of Tampa. The Suncoast Parkway as well as U.S. 19, U.S. 41, U.S. 98, U.S. 301, and Interstate 75 all pass through Pasco. The county is directly west of Polk and Sumter counties, north of Hillsborough and Pinellas counties, and south of Hernando County. Pasco County was created on June 2, 1887, from

1705-714: A disaster area, which provided for the cost of debris removal and emergency services. In the immediate aftermath, the Federal Emergency Management Agency (FEMA) funded crisis counseling services for storm victims, set up by the Puerto Rico Department of Health/ Mental Health and Anti-Addiction Services Administration. After the storm's passage, FEMA established six disaster recovery centers. Ultimately, more than 206,000 people applied for disaster assistance, including grants for essential repairs and temporary housing. FEMA approved

1860-405: 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

2015-506: 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

2170-481: A household in the county was $ 32,969, and the median income for a family was $ 39,568. Males had a median income of $ 30,974 versus $ 23,802 for females. The per capita income for the county was $ 18,439. About 7.60% of families and 10.70% of the population were below the poverty line , including 15.20% of those under age 18 and 7.70% of those age 65 or over. Though the county seat is in Dade City, duplicate county government offices and court facilities are also located in

2325-464: 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

2480-464: 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

2635-634: A local train (the last passenger train for the region north of St. Petersburg and west of Dade City) through those towns from Jacksonville and Gainesville , bound for St. Petersburg. Prior to the 1967 merger for the SCL that service had been the western branch of the ACL's Champion from New York City. Until 1968 the SCL ran its Sunland from Washington, DC and Portsmouth, VA to Tampa. The SAL Tarpon Springs branch line from Tarpon Junction 14 miles west of Tampa to Elfers and thence to Newport Richey to New Port Richey

2790-608: A massive pit from dump trucks, despite objections to their ceremonious nature and discouragement from the World Health Organization, due to the popular but incorrect belief that dead bodies would lead to catastrophic outbreaks of exotic diseases. In the Dominican Republic , the storm dumped torrential flooding rains and killing over two dozen. Damage totaled $ 270 million (2004 USD). Millions in Florida were left without electricity, some for

2945-469: A mobile integrated health program to help those after an overdose . The program can help patients with medical and dental needs, mental health and therapy, transportation to medical appointments, withdrawal management, counseling, and shelter/housing. The agency has two arson investigators and three fire investigators that determine the origin and cause of fires throughout unincorporated Pasco County. Pasco County Fire Rescue conducts all fire inspections within

3100-426: 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

3255-493: 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

3410-642: A parking lot at the Jewfish Creek Bridge . Due to spring tides and elevated waters in Florida Bay , minor tidal flooding occurred at the Key West International Airport . Property damage was minor, totaling to only $ 5,000 (2004 USD). Following the passage of the storm, two people died due to carbon monoxide poisoning after running a generator in closed space without proper ventilation. Two others died and another

3565-422: 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

3720-429: 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

3875-579: A result of high tides, marinas were damaged at the Fort Pierce Inlet , which, in turn, destroyed numerous boats. A private residence near the Fort Pierce Inlet recorded a wind gust of 128 mph (206 km/h). Throughout the county, high winds damage or destroyed thousands of homes and businesses, as well as several mobile home communities. One man was injured when he ran his truck over a downed power line. In St. Lucie County, damage

4030-546: A result of strong winds, more than 49,300 houses were either damaged or destroyed. An elderly woman was injured while evacuating her home; she died from her injuries a few days later. Damage was severest in Indian River County, with estimates of losses in excess of $ 2 billion (2004 USD). To the south in St. Lucie County , Jeanne produced tides at an estimated height of 10 feet (3.0 m) above normal. As

4185-569: 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

4340-581: 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

4495-405: 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

4650-529: 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,

4805-461: 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

4960-401: 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

5115-414: A two-digit number and suffix letter by the warning centers that monitor them. Pasco County, Florida Pasco County is a county located on the west central coast of the U.S. state of Florida . According to the 2020 census , the population was 561,691, making it the eleventh-most populous county in the state. Its county seat is Dade City , and its largest city is Zephyrhills . The county

5270-831: A typhoon. This happened in 2014 for Hurricane Genevieve , which became Typhoon Genevieve. 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

5425-473: Is a rapidly rotating storm system with a low-pressure center, a closed low-level atmospheric circulation , strong winds, and a spiral arrangement of thunderstorms that produce heavy rain and squalls . Depending on its location and strength, a tropical cyclone is called a hurricane ( / ˈ h ʌr ɪ k ən , - k eɪ n / ), typhoon ( / t aɪ ˈ f uː n / ), tropical storm , cyclonic storm , tropical depression , or simply cyclone . A hurricane

5580-696: Is a strong tropical cyclone that occurs in the Atlantic Ocean or northeastern Pacific Ocean . A typhoon occurs in the northwestern Pacific Ocean. In the Indian Ocean and South Pacific, comparable storms are referred to as "tropical cyclones". In modern times, on average around 80 to 90 named tropical cyclones form each year around the world, over half of which develop hurricane-force winds of 65  kn (120 km/h; 75 mph) or more. Tropical cyclones typically form over large bodies of relatively warm water. They derive their energy through

5735-415: Is assumed at this stage that a tropical cyclone has become self-sustaining and can continue to intensify without any help from its environment. Depending on its location and strength, a tropical cyclone is referred to by different names , including hurricane , typhoon , tropical storm , cyclonic storm , tropical depression , or simply cyclone . A hurricane is a strong tropical cyclone that occurs in

Around the world, tropical cyclones are classified in different ways, based on the location ( tropical cyclone basins ), the structure of

6045-554: Is currently no consensus on how climate change will affect the overall frequency of tropical cyclones. A majority of climate models show a decreased frequency in future projections. For instance, a 2020 paper comparing nine high-resolution climate models found robust decreases in frequency in the Southern Indian Ocean and the Southern Hemisphere more generally, while finding mixed signals for Northern Hemisphere tropical cyclones. Observations have shown little change in

6200-414: Is cut off from its supply of warm moist maritime air and starts to draw in dry continental air. This, combined with the increased friction over land areas, leads to the weakening and dissipation of the tropical cyclone. Over a mountainous terrain, a system can quickly weaken. Over flat areas, it may endure for two to three days before circulation breaks down and dissipates. Over the years, there have been

6355-702: Is estimated that wind gusts in excess of 115 mph (185 km/h) occurred in the southern portions of the county. Throughout the county, rainfall was mostly between 6 and 8 inches (150 and 200 mm), which flooded streets and roads in the Palm Bay area. In addition, a man in Palm Bay drowned after driving his car into a flooded ditch. Damage in Brevard County was estimated at $ 320 million (2004 USD). High winds also significantly affected Lake County . The highest wind sustained wind speed reported

8060-620: The African easterly jet and areas of atmospheric instability give rise to cyclones in the Atlantic Ocean and Caribbean Sea . Heat energy from the ocean acts as the accelerator for tropical cyclones. This causes inland regions to suffer far less damage from cyclones than coastal regions, although the impacts of flooding are felt across the board. Coastal damage may be caused by strong winds and rain, high waves (due to winds), storm surges (due to wind and severe pressure changes), and

8215-611: The Appalachian Mountains , it continued producing heavy rains and flash flooding. Rainfall exceeded 6.00 inches (150 mm) as far north as New Jersey and Pennsylvania , resulting in severe flash flooding in Philadelphia, Pennsylvania and its Pennsylvania and New Jersey suburbs on September 28. Tornadoes also touched down in Wilmington, Delaware and Cherry Hill, New Jersey . Throughout Delaware,

The calculation of

8835-651: The Keys made sense. The center of Jeanne's eye achieved landfall near Stuart, at virtually the identical spot that Frances had come ashore three weeks earlier, the first time in record keeping that a hurricane made landfall in the same place as a previous storm of the same season. Maximum winds at the time of landfall were estimated to be near 120 mph (193km/h). In its early states, Jeanne dropped heavy rainfall in Guadeloupe, peaking at 11.81 inches (300 mm). The communes of Bouillante , Deshaies , and Pointe-Noire were

Although the GOP had the most votes in 2008 at the time, it was by a much smaller margin than the previous 2004 election and in subsequent elections, when

11315-632: 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}

11470-678: The Río Grande de Añasco. The storm left heavy crop damage in the southern and eastern portion of the island, particularly to coffee, plantain, banana, and wheat crops. In Jayuya , the storm destroyed 30% of the coffee crop. Of the $ 101.5 million crop damage total, more than half was from the banana crop. Overall, more than 15,500 acres (63 km; 24.2 sq mi) of croplands were affected. Overall, Jeanne killed four people directly and another four indirectly in Puerto Rico; damage totaled $ 169.5 million (2004 USD), making it

11625-463: 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

11780-610: 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

11935-591: 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

12090-655: The Zephyrhills Public Library. The Pasco County Libraries operated on a budget of $ 6,205,291 for fiscal year 2016–2017. Pasco Libraries circulated 2,623,024 items during that period. The head of library services reports to the Assistant County Administrator for Public Services. The New Port Richey Public Library is located in the New Port Richey area of Pasco County. It is the only public library in Pasco County that

12245-550: The afternoon of September 17, tropical storm warnings were dropped for the remainder of Hispaniola. In the Bahamas, the first hurricane watch was issued at 2100 UTC on September 15 and included Acklins and Crooked Islands , Inagua , Mayaguana , Ragged Island , and Turks and Caicos Islands . By 1500 UTC the next day, that hurricane watch was upgraded to a hurricane warning. Simultaneously, another hurricane watch became in effect for Cat Island , Exuma , Long Island , Rum Cay , and San Salvador . The hurricane warning

12400-623: The churches and schools on Abaco Islands, Eleuthera, Grand Bahama. At least 700 people went to a shelter in Abaco Islands alone. Preparations in Central Florida were rushed and sudden, as it did not become apparent that the storm would make a direct hit until the morning of the 23rd. Indeed, it had appeared the storm would pass safely offshore just the night before. Voluntary evacuations were advised on Thursday and Friday, plans for opening shelters on Saturday were distributed to

12555-546: The city of Ferry. About a dozen boats were beached or capsized. Many roads and bridges were inflicted with damage. In Point-Noire, nearly 300 single-family homes were damaged or demolished. Three bridges were destroyed, while numerous roads were also affected. Further south in Vieux-Habitants , roads also suffered damage, particularly in the Beaugendre area, leaving a dozen households isolated. A primary school

12710-536: The continental United States was $ 7.5 billion, plus an additional $ 270 million in the Dominican Republic and $ 169.5 million in Puerto Rico. Tropical Depression Eleven formed from a tropical wave 70 miles (110 km) east-southeast of Guadeloupe in the evening of September 13, and was upgraded to Tropical Storm Jeanne the next day. Jeanne passed south of the U.S. Virgin Islands on September 15, making landfall near Yabucoa, Puerto Rico later

12865-489: The county peaked at 11.97 inches (304 mm) in Kenansville , which was the highest rainfall total associated with Hurricane Jeanne. Due to heavy rainfall, flash flooding was reported, especially in the northern portions of the county. Streets and roads along U.S. Route 192 were inundated in the vicinity of St. Cloud . Damage to agriculture was also significant, totaling to an $ 8 million (2004 USD). Although

13020-521: The county. As of the census of 2000 , there were 344,765 people, 147,566 households, and 99,016 families residing in the county. The population density was 463 inhabitants per square mile (179/km ). There were 173,717 housing units at an average density of 233 per square mile (90/km ). The racial makeup of the county was 93.70% White , 2.07% Black or African American , 0.35% Native American , 0.94% Asian , 0.03% Pacific Islander , 1.52% from other races , and 1.38% from two or more races. 5.69% of

13175-435: 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

13330-492: 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

13485-469: 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

13640-481: 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

13795-410: 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

13950-634: The former Tampa and Thonotosassa Railroad along the east side of US 301 that spanned from Sulphur Springs to Zephyrhills, part of the Orange Belt Railway which became the Atlantic Coast Line Railroad which ran from St. Petersburg and entered the county in what is today Trinity to Trilby (abandoned during the early to mid-1970s), and a branch of the Seaboard Air Line that ran through Holiday , Elfers and into New Port Richey . The Atlantic Coast Line Railroad until 1957 ran

14105-453: 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

14260-532: 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

14415-517: The hardest hit. In Bouillante, 60 homes were damaged. The storm ruptured water pipes in the city of Bois Malher, isolating about 1,000 people. Damage to businesses resulted in 30 employees being laid-off. Crops also suffered impact, especially bananas. At the Malendure resort, which is located along the coast, the pier, restaurants, and dive base were rendered unusable. In Deshaies, 110 homes were severely damaged, including 60 in

14570-451: 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),

14725-522: 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

14880-472: The island Vieques with a total of 23.75 in (603 mm) in three days. There, a 24‑hour total of 14.75 in (375 mm) was reported, a 1 in 100 year event. On the Puerto Rican mainland, the rainfall averaged from 5–15 in (130–380 mm), peaking at 19.2 in (490 mm) at Aibonito in the center of the island. At that station, the rainfall reached 15 in (380 mm) in

15035-693: 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

15190-404: 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

15345-399: The morning of September 14, tropical storm warnings were issued for St. Kitts and Nevis, while tropical storm watches were issued for Anguilla. During the afternoon, tropical storm warnings were lowered for Saba, St. Eustatius, and St. Maarten, while hurricane warnings were issued for Puerto Rico and the U.S. Virgin Islands. Late on the morning of September 15, a hurricane watch was issued for

15500-643: The morning of September 15, hurricane warnings were issued from Cabrera to Isla Saona, while hurricane watches and tropical storm warnings were raised from Cabrera to Puerto Plata. That evening, hurricane warnings were extended westward from Cabrera to Puerto Plata while hurricane watches and tropical storm warnings were issued from Puerto Plata to Monte Cristi. Late in the morning of September 16, tropical storm warnings were issued from Môle-Saint-Nicolas to Puerto Plata. That afternoon, hurricane warnings were downgraded to tropical storm warnings from Puerto Plata to Isla Saona while all hurricane watches were dropped. Late on

15655-642: The most damaging tropical cyclone since Hurricane Georges in 1998. By September 17, heavy rains totaling about 13 in (330 mm) in the northern mountains of Haiti caused severe flooding and mudslides in the department of Artibonite , causing particular damage in the coastal city of Gonaïves , where it affected about 80,000 of the city's 100,000 residents. As of October 6, 2004 the official report counted 3,006 people dead, with 2,826 of those in Gonaïves alone. Another 2,601 people were injured. Decades of deforestation left surrounding valleys unable to hold

15810-558: The northeastern Caribbean Sea the storm steadily intensified and by late on September 14 Jeanne was forecast to move across the island as a minimal hurricane. As a result, the tropical storm warning was upgraded to a hurricane warning. Ultimately, Jeanne made landfall at 1600  UTC on September 15 as a 70 mph (110 km/h) tropical storm, about 17 mi (27 km) east of Guayama . Prior to hitting, 3,629 people evacuated to 159 schools converted into emergency shelters. Governor Sila María Calderón forbade

15965-522: 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

16120-677: The open Atlantic. Jeanne is blamed for at least 3,006 deaths in Haiti with about 2,800 in Gonaïves alone, which was nearly washed away by floods and mudslides. The storm also caused 18 in the Dominican Republic , 8 deaths in Puerto Rico , and 5 in the rest of the United States , bringing the total number of deaths to at least 3,037, making Hurricane Jeanne one of the deadliest Atlantic hurricanes ever recorded. Final property damage in

16275-466: 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

16430-444: The population were Hispanic or Latino of any race. There were 147,566 households, out of which 23.50% had children under the age of 18 living with them, 54.60% were married couples living together, 8.90% had a female householder with no husband present, and 32.90% were non-families. 27.30% of all households were made up of individuals, and 15.90% had someone living alone who was 65 years of age or older. The average household size

16585-440: 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

16740-413: 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

16895-576: The public, and Florida Power and Light warned that power could be out "for an extended period of time". Canals were also drained on the same day. On Friday, the Palm Beach Zoo prepared for the storm by moving small animals and birds into buildings such as restrooms and restaurants. Evacuations began in earnest, with many residents leaving for the Keys, noting that the islands were the only location definitely out of harm's way. For once, evacuation to

17050-479: The raw vote for the Republican candidate increased every time. Pasco County Public Transportation provides bus service throughout Pasco County. CSX operates three rail lines within the county. Dade City and Zephyrhills are served with a line from Plant City. Amtrak formerly provided passenger rail service to Dade City on that line, but the stop was terminated in late 2004. The other two lines include

17205-444: 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

17360-543: The remnants of Jeanne produced between 4 and 8 in (100 and 200 mm) of rain, peaking at 7.1 in (180 mm) at the University of Delaware . This led to widespread street flooding and several rivers overflowed their banks. Forty people had to be rescued from a bus along the White Clay Creek after the creek crested at .59 ft (0.18 m) above flood-stage. A strong F2 tornado touched down in

17515-578: The request for 155,933 people, providing $ 401.1 million in aid. In March 2005, the US Government provided $ 14.6 million in aid for reconstruction projects, including repairs to the power grid, as well as general road and bridge restoration. Due to its damage along its path, Hurricane Jeanne was retired by the World Meteorological Organization in Spring 2005, meaning the name will never be used again for an Atlantic hurricane . The name

17670-424: The sale of alcohol during the storm. All ports around the island were closed, and most flights were canceled. Due to the threat for downed wires, the governor ordered for the entire island's power grid to be turned off during the storm. During Hurricane Hugo in 1989, six people were electrocuted to death, which influenced the decision. In addition, ferry trips from the main island to Vieques and Culebra stopped during

17825-473: The same day. After crossing Puerto Rico , Jeanne reached hurricane strength on September 16 near the eastern tip of the Dominican Republic on the island of Hispaniola , but fell back to tropical storm strength later that day as it moved across the mountainous island. Jeanne moved offshore the Dominican Republic late in the afternoon of September 17. By that time, Jeanne had weakened to tropical depression strength. Even though Jeanne did not strike Haiti directly,

17980-492: 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

18135-492: 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

18290-513: 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

18445-583: The southern coast. In Cayey , located in the center of the island, a 72 mph (116 km/h) gust was reported, just shy of hurricane force. Additionally, the Luis Muñoz Marín International Airport in San Juan reported sustained winds of 49 mph (79 km/h). In Yabucoa , the winds killed one woman after she was flung into a wall. Most of Jeanne's impact came from its rainfall. The heaviest precipitation fell on

18600-485: The southern third of Hernando County. The same legislation also created Citrus County from the northern third of Hernando County. The county was named after Samuel Pasco , who had just been elected to the United States Senate . Dade City was named the temporary county seat until a popular vote was held in 1889, at which time voters made Dade City the permanent county seat. As early as 1917, residents of

18755-415: The state, injuring five people and leaving $ 1 million in damages. The tornado touched down in northern New Castle County and tracked for 5 mi (8.0 km) and generated winds up to 130 mph (210 km/h). The county airport sustained significant damage, five C-130 cargo planes were damaged, thousands of pounds of jet fuel spilled, and damaged hangars. At a nearby industrial park, metal siding

18910-553: The state. Numerous reports of stranded vehicles were sent to the Emergency Operations Center. In Carroll County , a group of inmates required rescue after the jail they were in flooded. One brief F0 tornado touched down in the state near Solomons , causing minor damage. Two tornadoes were spawned by Hurricane Jeanne in Brevard County , both of which tracked through Micco and were of F1 intensity on

19065-877: The storm made landfall well to the south, Indian River County was severely affected due to the right eyewall passing through. One F1 tornado was spawned by the Jeanne in Vero Beach . It moved near the intersection of Florida State Road 60 and Interstate 95 , where it felled numerous trees, resulting in approximately $ 20,000 (2004 USD) in damage. Rainfall in the county was mostly between 6 and 8 inches (150 and 200 mm), which flooded streets and roads, especially in Vero Beach. The highest wind gusts in Indian River County were 122 mph (196 km/h) at Vero Beach and 116 mph (187 km/h) in Sebastian . As

19220-402: The storm was large enough to cause flooding and mudslides, particularly in the northwestern part of the country. On September 18, while the system was being tracked near Great Inagua and Haiti , a new center formed well to the northeast and the previous circulation dissipated. The system restrengthened, becoming a hurricane on September 20. Jeanne continued to meander for several days (making

19375-638: The storm. Effects from Hurricane Jeanne were reported as far south as Monroe County . The highest winds gusts in the county were 51 mph (82 km/h) at the Sombrero Key Light C-Man Station and 49 mph (79 km/h) at the Molasses Reef C-Man Station. Storm tides were 1 foot (0.30 m) above normal on Vaca Key ; it is estimated that tides reaching 2.5 feet (0.76 m) above average occurred near North Key Largo . The surge of water inundated

19530-486: The storm. In Vega Baja , an elderly man fell from a roof to his death while installing storm shutters. As Jeanne moved ashore, an eye was in the process of developing, indicating winds near hurricane status, although hurricane-force winds still affected higher elevations. Jeanne quickly crossed Puerto Rico and eventually attained hurricane status in the Mona Passage between the island and Dominican Republic . On

19685-617: 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

19840-419: 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

19995-483: 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

20150-648: 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

20305-542: The system moved back into the Atlantic offshore the New Jersey coast the next day. Hurricane Jeanne originated as a tropical depression on September 13 from a tropical wave , just east of the Lesser Antilles . At that time, the United States government issued a tropical storm warning for the entirety of Puerto Rico, about 43 hours prior to Jeanne making landfall on the island. As it moved through

20460-534: The third time in a month. There were five direct deaths in the mainland United States, three in Florida , one in South Carolina and one in Virginia . The final US damage was determined to be around $ 7.5 billion. It was difficult to isolate this from damage caused by Hurricane Frances (and, around Polk County and Highlands County , from Hurricane Charley as well). As the storm moved northward east of

20615-423: 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

20770-687: The tropical storm warning was canceled. Early on the following day, the hurricane warning was downgraded to a tropical storm warning for Abaco Islands, Berry Islands, Bimini and Grand Bahama Island, while the remaining portion – Andros Islands, Eleuthera and New Providence – was discontinued. All tropical cyclone warnings and watches were canceled by 0900 UTC on September 26. Because Hurricane Frances struck only about two week prior, numerous houses were still patched with plastic sheeting on their roofs, while other residents were still living with neighbors or relatives. Officials urged residents in low-lying homes to evacuate. Shelters were set up at

20925-636: The unincorporated portions of the county. The Pasco County Jail is managed by the Pasco County Corrections Department. New Port Richey: The New Port Richey Fire Department provides fire protection services within the City of New Port Richey . The Department has 2 Fire stations located within the City. Pasco County Fire Rescue covers all emergency medical services for the New Port Richey Fire Department. New Port Richey Police Department

21080-427: The water system; about 600,000 people were left without running water. Throughout Puerto Rico, Jeanne heavily damaged schools, houses, businesses. Strong wind gusts left 70% of the island without power, and damage to the electrical grid totaled $ 60 million (2004 USD). The combination of fallen trees, landslides, and debris closed 302 roads and left many bridges damaged. 400 people had to evacuate near

21235-451: 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

21390-500: The western part of the county proposed forming a separate county or merging with Pinellas County, as Dade City was not centrally located in the county. The issue was finally resolved in the late 1970s with the construction of identical government centers in both Dade City and New Port Richey. The earliest towns were Anclote, Blanton, Dade City , Earnestville, Fort Dade (not to be confused with Fort Dade on Egmont Key ), Macon ( Trilby ), Lacoochee , St. Leo , and San Antonio . Citrus

21545-402: 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

21700-795: 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 .
