Timeline of the 1990 Atlantic hurricane season

The 1990 Atlantic hurricane season featured the most named storms of any hurricane season at the time. During the season, 14 tropical cyclones in the Atlantic Ocean became named storms. Although Tropical Depression One formed on May 24, the season officially began on June 1; it ended on November 30, dates that conventionally delimit the period of each year when most tropical cyclones develop in the Atlantic basin. The season's final storm, Hurricane Nana, dissipated on October 21.

Contents

The season produced 16 tropical depressions, of which 14 intensified into tropical storms, 8 became hurricanes, and 1 became a major hurricane. Although the season had the highest number of named storms at the time, it featured only two notable storms, primarily because many of the tropical cyclones remained either weak or at sea. The two most significant storms of the season, in terms of damage and loss of life, were Hurricane Diana and Tropical Storm Marco. However, the strongest tropical cyclone of the season was Hurricane Gustav.

This timeline includes information that was not operationally released, meaning that data from post-storm reviews by the National Hurricane Center, such as a storm that was not operationally warned upon, has been included. This timeline documents tropical cyclone formations, strengthening, weakening, landfalls, extratropical transitions, and dissipations during the season.
