Track map of all storms during the season.

The Timeline of the 1999 Atlantic hurricane season documents all the storm formations, strengthening, weakening, landfalls, extratropical transitions, as well as dissipation. The timeline also 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 on, has been included. The 1999 Atlantic hurricane season was slightly above average in terms of activity, with 12 tropical cyclones, 8 hurricanes, and 5 major hurricanes (hurricanes that are classified as Category 3 or higher).
