The meteorological history of Hurricane Jeanne lasted for about two weeks in September 2004. Hurricane Jeanne was the eleventh tropical cyclone, tenth named storm, seventh hurricane, and sixth major hurricane of the 2004 Atlantic hurricane season. It formed from a tropical wave on September 13 near the Lesser Antilles, and encountered favorable enough conditions to reach tropical storm status. Jeanne strengthened further in the eastern Caribbean, becoming a strong tropical storm and developing an eye before striking Puerto Rico on September 15. Remaining well-organized, it attained hurricane status before hitting the eastern tip of the Dominican Republic on September 16.
Hurricane Jeanne steadily weakened while crossing eastern
The hurricane produced heavy rainfall across its path, including in Haiti where precipitation caused devastating mudslides; over 3,000 deaths were reported in the country. Heavy rainfall also occurred during its landfalls on Puerto Rico and Florida, resulting in river flooding. In its strongest landfall, the hurricane produced strong winds across an area earlier affected by Hurricane Frances and, in some locations, by Hurricane Charley. Late in its duration, the combination of moisture from Jeanne and cool air resulted in a tornado outbreak that extended from Georgia through the Mid-Atlantic states.
Formation and first landfall
The origins of Hurricane Jeanne were from a
Late on September 12, while approaching the northern Lesser Antilles, convection increased and became better organized around an area of increased cyclonic turning.[8] Environmental conditions became more favorable, allowing for the development of a low-pressure area and for banding features to increase.[9] Late on September 13, with the formation of a broad low-level circulation, it is estimated the system developed into Tropical Depression Eleven about 70 mi (110 km) east-southeast of Guadeloupe.[10]
Upon first becoming a tropical cyclone, the depression was located to the south of the
Tropical Storm Jeanne quickly organized over the eastern Caribbean Sea, developing a tight inner core and well-defined outflow as it tracked over warm water temperatures of about 84 °F (29 °C). Initially, the storm was forecast to attain hurricane status before crossing Puerto Rico.[13] However, its organization deteriorated by early on September 15, with radar imagery tracking a low-level circulation moving away from the convection.[14] The temporary weakening was due to increased shear and dry air.[15] At 1600 UTC on September 15, Jeanne made landfall near Guayama, Puerto Rico with winds of 70 mph (110 km/h),[1] and as it moved ashore it was in the process of developing an eye.[16] Across the territory, the storm produced heavy rainfall, peaking at 23.75 inches (603 mm) on Vieques Island. Rainfall across the region resulted in moderate to severe river flooding, with several river stations in Puerto Rico reporting historical levels. Light winds, generally around tropical storm force, affected the region as well.[1]
Second landfall and reorganization
Tropical Storm Jeanne remained over Puerto Rico for about eight hours,[1] during which it maintained its eye feature and well-defined inner core of convection.[17] It intensified over the Mona Passage, and attained hurricane status as it struck the eastern tip of the Dominican Republic on September 16. Continuing slowly west-northwestward near the coast, Jeanne quickly weakened to tropical storm status,[1] and by 24 hours after landfall its convection had deteriorated as the eye feature dissipated.[18] Late on September 17, it emerged into the Atlantic Ocean as a tropical depression, after having dropped torrential rainfall across Hispaniola. Catastrophic flooding and mudslides were experienced in Haiti, including in the coastal city of Gonaïves, and over 3,000 deaths were reported in the country.[1]
On September 17, while it was over Hispaniola, the National Hurricane Center issued a forecast that predicted Jeanne to make landfall near Savannah, Georgia in about five days. However, the forecast noted uncertainty in regards to the steering currents, which depended on the movement of the remnants of Hurricane Ivan and a ridge building behind it.[19] After it left the nation as a tropical depression, the original center of circulation tracked westward away from the convection and dissipated. However, a new circulation developed closer to the convection, and Jeanne regained tropical storm status on September 18. By then, the mid-level circulation associated with Hurricane Ivan had combined with a trough to weaken the ridge located across the western Atlantic Ocean; this caused Jeanne to track northward through the Turks and Caicos Islands.[1]
As it tracked northward, the storm failed to organize at first, due to the influence of an upper-level low to its south. The circulation became broad and elongated, as well as removed from the deepest convection.[20] However, after moving away from the low, the convection became better organized and more associated with the convection.[21] After some initial slow organization continued, an area of deep convection developed over the center midday on September 20.[22] An eye developed within the convection,[23] and late on September 20 Jeanne re-attained hurricane status about 350 mi (560 km) east-northeast of the Abaco Islands in the Bahamas.[1]
While intensifying as a tropical storm, the National Hurricane Center faced difficulties in the future track of Jeanne, based on two major divergences between
Peak intensity and final landfall
Hurricane Jeanne steadily intensified as it turned eastward, developing a 52 mi (84 km) wide eye.[25] A motion to the southeast began on September 22, and around the same time it reached winds of 100 mph (160 km/h), making it a Category 2 hurricane on the Saffir–Simpson scale.[1] At the same time, the National Hurricane Center forecast to turn westward and later northwestward, with its projected five-day track within 60 mi (97 km) of Cape Fear, North Carolina. The westernmost outlier during one model run was the NOGAPS model, which predicted a continued westward motion across central Florida.[26] The official forecast changed early on September 23 to bring Jeanne across northeastern Florida, though initially the cyclone was predicted to turn northeastward and hit South Carolina as a hurricane.[27]
By September 23, Jeanne had begun a slow westward motion, with its previously well-defined eye becoming ragged.[28] It moved slowly over waters it traversed just four days prior, causing upwelling; this is the process in which a stationary storm causes the water temperatures to decrease by bringing the cooler, deeper waters to the surface. As a result, Jeanne weakened to a minimal hurricane midday on September 23,[1] though it was forecast to re-intensify and attain major hurricane status.[28] By early on September 24, the winds had decreased to 80 mph (130 km/h);[1] its convection weakened in intensity,[29] and the eyewall eroded due to dry air entrainment.[30] However, as Jeanne moved toward an area of warmer waters, deep convection redeveloped around the eye.[31] Its favorable upper-level environment allowed the outflow to become better defined, with a large eye and nearby dry air being the primary restraining factors for development.[32] At 1200 UTC on September 25, Jeanne attained major hurricane status, and two hours later it made landfall on Abaco Island.[1]
After it had been previously forecast to turn northwestward and track along the northeastern Florida coast,
Upon moving inland in east-central Florida, the hurricane produced a
Dissipation
As Hurricane Jeanne moved inland, its inner eyewall dissipated,
As it moved northward, Jeanne continued to drop moderate to heavy rainfall, including over 7 inches (180 mm) in southern Georgia.[37] A cold front across the region caused the depression to accelerate northeastward, combining moisture from the Gulf of Mexico with cool and stable air over the Carolinas. This combination produced severe thunderstorms across the region,[41] spawning six tornadoes in Georgia,[42] eight in South Carolina,[43] and eight in North Carolina.[41]
After crossing into Virginia, Jeanne transitioned into an extratropical cyclone by September 29 near Washington, D.C.[1] In Wilmington, Delaware, the storm spawned an F2 tornado.[44] Across the Mid-Atlantic and New England, moisture from the storm produced light to heavy rainfall, with totals of over 7 inches (180 mm) near Philadelphia and Nantucket.[37] Subsequent to becoming extratropical, the remnants of Jeanne turned eastward, exited into the Atlantic Ocean, and merged with a cold front.[1]
