The season officially began on June 1, 1983 and ended on November 30, dates which conventionally limit the period of each year when tropical cyclones tend to form in the Atlantic. The first named storm, Hurricane Alicia, formed on August 15. The last storm of the season, Tropical Storm Dean, dissipated on September 30. This timeline documents tropical cyclone formations, strengthening, weakening, landfalls, extratropical transitions, as well as dissipations during the season.
