2005 WMHB Atlantic hurricane season

The 2005 Atlantic hurricane season was an extremely active hurricane season in the north Atlantic. It is tied with the 1995 season for the second-most active season since records began in 1851. The season featured 21 named storms, 12 hurricanes, and 6 major hurricanes. The season officially started on June 1 and ended on November 30. However, as shown by Tropical Storm Arlene in the month of April, tropical cyclone formation is possible at other times of the year. The season's strongest storm was Hurricane Katrina, which became one of the most intense Atlantic hurricanes ever recorded. Katrina was one of two Category 5 hurricanes in 2005, the other being Hurricane Rita.

Storm Names
The following names were used for storms that formed in the north Atlantic during 2005. This list is the same list that was used in the 1999 season except for Don and Lee, which replaced Dennis and Lenny. All 21 names were used in 2005, the third occurrence of this happening in history.

Retirement
In the spring of 2006 at its annual meeting, the World Meteorological Association retired the names Floyd, Katrina, Maria, and Rita from its rotating name lists. They were replaced by Franklin, Katia, Maggie, and Rina for the 2011 season.
