Timeline of the 1985 Atlantic hurricane season

The 1985 Atlantic hurricane season was an event in the annual Atlantic hurricane season in the north Atlantic Ocean. It featured average activity overall, with thirteen tropical cyclones, eleven tropical storms, seven hurricanes, and three major hurricanes.[1] The season officially began on June 1, 1985 and ended November 30, 1985. These dates, adopted by convention, historically describe the period in each year when most systems form.[2] The season's first storm, Tropical Storm Ana, developed on July 15; the season's final storm, Tropical Depression Thirteen, dissipated on December 9.

Season summary map

The 1985 season was particularly destructive and disruptive for the United States, with damage amounting to a then-record US$4 billion. The entire coastline from Brownsville, Texas, to Eastport, Maine, was under a gale warning at some point during the year and a portion of every coastal state was under a hurricane warning.[3] Eight tropical cyclones made landfall in the United States, including a record-tying six hurricanes, the most in a single year since 1916.[4][3]

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).[5] In this time line, all information is listed by UTC first with the respective local time included in parentheses.
