caption_attribution_description: The MODIS instrument aboard NASA's Aqua satellite captured this true-color image of Hurricane Ivan on Septebmer 13, 2004 at 19:00 UTC (3:00 PM EDT). At the time this image was taken Ivan was located approximately 110 km (70 miles) south-southeast of the western tip of Cuba and was moving towards the northwest at 13 km/hr (8 mph). Ivan had maximum sustained winds of 260 km/hr (160 mph) with higher gusts. The MODIS Rapid Response System provides this image at additional resolutions and formats.
context_page_description: The 2004 Atlantic hurricane season was notable as one of the deadliest and most costly Atlantic hurricane seasons on record. It officially began on June 1, 2004 and ended on November 30, although storm activity continued into December. This timeline documents tropical cyclone formations, strengthening, weakening, landfalls, extratropical transitions, as well as dissipations. 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, of which, 15 became named storms. Of these, 9 strengthened into hurricanes with 6 intensifying into major hurricanes. 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 sustained winds: Tropical Storm Bonnie, Charley, Frances, Ivan, and Jeanne. This is the only time in recorded history that four hurricanes affected the U.S.
