Jeanne appears to have her origins about 2000 miles to the east of the Leeward Islands off the coast of Africa as a weak tropical wave that appeared around 7 September (See Figure 2). The wave moved unchanged across the Atlantic until organizing sufficiently to be named Tropical Depression Eleven on 13 September. Jeanne made rather slow progress towards the west-northwest at 10-15 mph under a strong sub-tropical high pressure system to her north, which gave her time over warm water to strengthen into a Tropical Storm on 14 September.2
On 15 September, Jeanne made landfall in southeastern Puerto Rico as a strong 60 kt (70 mph) Tropical Storm. Jeanne maintained much of her intensity while tearing through the island, and emerged in the Mona Passage between Puerto Rico and the Dominican Republic as a 70 mph Tropical Storm early on 16 September. Jeanne finally reached hurricane intensity at 12 UTC on 16 September, right off the extreme eastern tip of Hispañola.3
Jeanne is responsible for over 3,000 deaths in Haiti caused by the torrential rains, which led to catastrophic mud slides—primarily in the city of Gonaives, where an estimated 200,000 individuals lost their homes.4
After passing over Haiti, Jeanne began a slow northward drift over the southern Bahamas. This extra time over water allowed Tropical Storm Jeanne to strengthen into a hurricane once again while completing a small anti-cyclonic loop a few hundred miles north of the Bahamas. On 23 September, Jeanne passed over her previous track, encountering her cool water upwelling produced a few days prior. This induced a brief period of weakening between 23 and 24 September as Jeanne’s maximum sustained winds decreased from 85 kt (100 mph) to 70 kt (80 mph). Once over warmer Caribbean waters, Jeanne intensified into a strong 105 kt (120 mph) Category 3 Hurricane a few hours before making landfall over Martin and St. Lucie counties in east central Florida.
Jeanne proceeded to ride up the spine of eastern Florida, producing heavy rains across the entire state. The highest reported total was 12 inches in Kenansville in South Central Florida. Jeanne finally weakened to a Tropical Storm on 26 September, and then to a Depression on 27 September, before merging with an approaching frontal boundary and becoming extratropical on 29 September.4
Estimates are that Jeanne is responsible for $6.9 billion (2004 USD) in damages.4
