While Jeanne was dumping rain over the
Caribbean countries, Hurricane Ivan moved over the Gulf of Mexico
across the southeastern United States. By 18 September, Ivan's mid-level circulation had combined with an extratropical
short wave trough in the westerlies and moved to the northeastern U.S. coast where it eroded the ridge to the north of Jeanne.
This placed Jeanne in a weak steering flow that persisted for five days. Jeanne first moved slowly northward over the
southeastern Bahamas as a tropical storm and then moved in an anticyclonic loop about 500 n mi east of the northwestern
Bahamas. Jeanne gradually strengthened to a hurricane with 100 mph winds by the time it completed this loop on 23
By 23 September, the extratatropical trough
previously located over the northeastern U.S. coast moved eastward
replaced by a large deep-layer migratory ridge that propelled Jeanne on a track just north of due westward. On 24 September,
Jeanne moved over its own previous track from a few days earlier and encountered cooler waters caused by upwelling from
the hurricane. This is believed to be a factor in the decreasing of the maximum winds from 100 mph to 80 mph by the
evening of 23 September. Continuing westward at 12 to 14 mph and moving away from the upwelled cooler water, the
winds increased to 115 mph (category three on the Saffir/Simpson hurricane scale) by the morning of 25 September as the
center moved over Abaco Island and then Grand Bahama Island in the northern Bahamas. Jeanne made landfall on the east
coast of Florida early on 26 September with the center of its 50-n mi diameter eye crossing the coast at the southern
end of Hutchinson Island just east of Stuart at midnight on the night of 25 September. Maximum winds at landfall are
estimated at 120 mph over a very small area north of the center and it is not clear whether these strongest winds reached
the coast or remained over water.
Jeanne moved across central Florida while
weakening and began to recurve around the western periphery of the
aforementioned migratory ridge. The hurricane weakened to a tropical storm while centered about 30 n mi north of
Tampa early in the afternoon of 26 September and then weakened to a tropical depression the next day while moving
northward across central Georgia accompanied by heavy rain. The depression, still accompanied by heavy rain moved
over the Carolinas, Virginia, and the Delmarva Peninsula. It merged with a frontal zone and became extratropical on the
evening of 28 September while moving eastward off of the U.S mid-Atlantic coast. Below is a track of the cyclone,
