Tropical cyclones become named storms when maximum sustained winds reach 39 miles per hour. Seven of the 2003 season's 14 storms became hurricanes, with three - Fabian, Isabel and Kate - becoming major hurricanes, according to the National Oceanic and Atmospheric Administration, also known as NOAA.
Six of the named systems hit the United States, said NOAA, a unit of the U.S. Department of Commerce.
This was the season of Isabel, which slammed into North Carolina as one of the strongest hurricanes on record with maximum sustained winds of 165 miles per hour, and Juan, the worst hurricane to hit Halifax, Nova Scotia, in modern history, and Fabian, the most destructive hurricane to hit Bermuda in more than 75 years.
NOAA said the years from 1995 through 2003 had been the most active period for Atlantic hurricanes on record. The 2003 Atlantic season officially ended on Nov. 30, which was Sunday.
Since 1995, seven of nine seasons have been above normal.
The 2004 Atlantic hurricane season officially begins on June 1.
