Timeline of the 1983 Atlantic hurricane season

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, during which four storms formed.[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] The most notable storm in 1983 was Hurricane Alicia, which killed 21 people and caused $2.6 billion (1983 USD; $5.6 billion 2008 USD) in damages, making it the costliest storm, at the time, in Texas history.[4] As a result of its intensity, the name Alicia was subsequently retired from reuse in the North Atlantic by the World Meteorological Organization.[5] Another notable storm, Hurricane Barry, made landfall on Florida as a tropical storm, then, after crossing into the Gulf of Mexico crossing, strengthened into a weak Category 1 hurricane that traveled almost due west across the Gulf before making landfall in extreme northern Mexico.[6]

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.

By convention, meteorologists one time zone when issuing forecasts and making observations: Coordinated Universal Time (UTC), and also use the 24-hour clock (where 00:00 = midnight UTC).[7] In this time line, all information is listed by UTC first with the respective local time included in parentheses.

gollark: My longer-term plan is to rewire the system to make more sense.
gollark: I would switch our fusion reactors to potatOS control, but only OC can manage them. Sad!
gollark: Fallen? You mean TechCorp 5?
gollark: It may also be in use on LurCraft.
gollark: Also TechCorp in various iterations but that is down.
