Timeline of the 1983 Atlantic hurricane season
From Wikipedia, the free encyclopedia
The 1983 Atlantic hurricane season was an event in the annual tropical cyclone season in the north Atlantic Ocean. It was the least active Atlantic hurricane season in 53 years.[1] The season officially began on June 1, 1983 and ended November 30, 1983. These dates, adopted by convention, historically describe the period in each year when most systems form.[2] The first named storm, Hurricane Alicia, formed on August 15. The last storm of the season, Tropical Storm Dean, dissipated on September 30.

This season produced seven tropical depressions, of which four became named storms; three attained hurricane status, of which one became a major hurricane, a storm that ranks as a Category 3 or higher on the Saffir–Simpson scale.[3] In all, three systems made landfall this season: Hurricane Alicia (in Southeast Texas), Hurricane Barry (in Florida and near the Mexico–Texas border), and Tropical Storm Dean (on the Delmarva Peninsula.
This timeline documents tropical cyclone formations, strengthening, weakening, landfalls, extratropical transitions, and dissipations during the season. It includes information that was not released throughout the season, meaning that data from post-storm reviews by the National Hurricane Center, such as a storm that was not initially warned upon, has been included.
The time stamp for each event is stated using Coordinated Universal Time (UTC), the 24-hour clock where 00:00 = midnight UTC.[4] and the time zone where the center of the tropical cyclone is currently located. The time zones utilized (east to west) prior to 2020 were: Atlantic, Eastern, and Central.[5] In this timeline, the respective area time is included in parentheses. Additionally, figures for maximum sustained winds and position estimates are rounded to the nearest 5 units (miles, or kilometers), following National Hurricane Center practice. Direct wind observations are rounded to the nearest whole number. Atmospheric pressures are listed to the nearest millibar and nearest hundredth of an inch of mercury.
