2004 WMHB Atlantic hurricane season (Cooper)

The 2004 Atlantic hurricane season was a hyperactive and catastrophic Atlantic hurricane season. With 17 named storms, 11 hurricanes, and 7 major hurricanes forming, it was one of the most active Atlantic hurricane seasons on record. The season officially began on June 1, 2018, and will end on November 30, 2018. These dates historically describe the period each year when most tropical cyclones form in the Atlantic basin and are adopted by convention.

Storm names
The following list of names was used for named storms that formed in the North Atlantic in 2004. The names not retired from this list were used again in the 2010 season. This was the same list used in the 1998 season, with the exceptions of Brenda, Gaston, and Matthew, which replaced Betty, Georges, and Mitch, respectively. The names Gaston, Matthew, Otto, Paula, and Richard were used for the first time this year, while Brenda had previously been used in 1955, 1960, 1964, 1968, and 1973.

Retirement
On April 5, 2005, at the 27th session of the RA IV hurricane committee, the World Meteorological Organization retired the names Charley, Earl, Frances, Ivan, and Jeanne from its rotating name lists due to the amount of damage and deaths they caused, and they will not be used again for another Atlantic hurricane. They were replaced with Colin, Edgar, Fiona, Igor, and Julia for the 2010 season.
