2005 WMHB Atlantic hurricane season (Cooper)

The 2005 Atlantic hurricane season was the most active Atlantic hurricane season in recorded history, with 31 named storms, 18 hurricanes, and 9 major hurricanes forming. The season officially began on June 1, 2005, and will end on November 30, 2005. These dates historically describe the period each year when most tropical cyclones form in the Atlantic basin and are adopted by convention. However, the season's last tropical cyclone, Tropical Storm Iota, did not dissipate until January 6 of the following year, marking the latest end to an Atlantic hurricane season on record.

Storm names
The following list of names was used for named storms that formed in the North Atlantic in 2005. The names not retired from this list were used again in the 2011 season. This was the same list used in the 1999 season, with the exceptions of Don, Gladys and Orla, which replaced Dennis, Gert and Ophelia, respectively. The names Don, Orla, Stan, Tammy, Vince, and Wilma were used for the first (and only, in the cases of Don, Stan, and Vince) time this year.

Retirement
On March 31, 2006, at the 28th session of the RA IV hurricane committee, the World Meteorological Organization retired the names Don, Emily, Lenny, Rita, Stan, and Vince 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 Desmond, Edith, Lee, Rina, Sean, and Vernon for the 2011 season.
