Timeline of the 2003 Atlantic hurricane season


The 2003 Atlantic hurricane season was an active Atlantic hurricane season with tropical activity before and after the official bounds of the season – the first such occurrence in 50 years. The season officially began on June 1, 2003 and ended on November 30. However, a pre-season storm, Tropical Storm Ana, led to the season starting on April 20, and storm activity continued through December 11. The timeline includes information which was not operationally released, meaning that information from post-storm reviews by the National Hurricane Center, such as information on a storm that was not operationally warned upon, has been included. This timeline documents tropical cyclone formations, strengthening, weakening, landfalls, extratropical transitions, as well as dissipations during the season.
This season had 21 tropical depressions, of which, 16 became named storms. Of these, 7 strengthened into hurricanes with 3 intensifying into major hurricanes. Hurricane Fabian, Hurricane Isabel, and Hurricane Juan had their names retired due to the impact caused in Bermuda, the eastern United States, and Nova Scotia respectively. Both Fabian and Juan were the worst hurricanes to hit their respective areas, causing $450 million in damages and 16 fatalities. Hurricane Isabel was the strongest, deadliest, and costliest storm of the season. Isabel peaked as a Category 5 hurricane over the open waters of the Atlantic; however, it weakened to a Category 2 before impacting the east coast of the United States, causing $3.6 billion in damages and 51 fatalities.
