Timeline of the 2004 Atlantic hurricane season

This timeline documents tropical cyclone formations, strengthening, weakening, landfalls, extratropical transitions, as well as dissipations during the 2004 Atlantic hurricane season, which officially began on June 1, 2004 and ended on November 30, although storm activity continued into December. The timeline includes information which was not operationally released, meaning that information from post-storm reviews by the National Hurricane Center, such as information on a storm that was not operationally warned upon, has been included.

This season had 16 tropical depressions, 15 named storms, nine hurricanes, and six major hurricanes, i.e. those that rank as Category 3 or higher on the Saffir-Simpson Hurricane Scale.cite web| author=NHC Hurricane Research Division| title=Atlantic hurricane best track ("HURDAT")| publisher=NOAA| date=2006-02-17|accessdate=2008-08-12| url=http://www.aoml.noaa.gov/hrd/hurdat/tracks1851to2007-apr08.txt] The most noteworthy storms for the season were the five named storms that made landfall in the U.S. states of Florida and Alabama, three of them with at least 115 mph (185 km/h) sustained winds (major hurricane strength): Tropical Storm Bonnie, Charley, Frances, Ivan, and Jeanne. This is the only time in recorded history that four hurricanes affected the U.S. State of Florida although one of the four, Ivan, brought hurricane force winds to the state without making a landfall there.
