The 2005 Atlantic Hurricane Season ran from June 1, 2005 to November 30, 2005 but storms can form during anytime of the year, demonstrated by Hurricane Arlene and Tropical Storm Bret. Waters were incredibly warm starting from late April to Mid-January, which supported rapid tropical development nearly year round. Warm waters from 2005 extended into part of 2006, getting a hurricane in the middle of January.
