1999 WMHB Atlantic hurricane season

The 1999 Atlantic hurricane season was a fairly active season, and the first since 1989 to feature a tropical cyclone in May. The season officially started on June 1 and ended on November 30. These dates conventionally delimit the time of year in which most tropical cyclones form in the Atlantic basin. However, as shown by Tropical Storm Arlene in May, tropical cyclone formation is possible at any time of the year.

The season's first storm was Tropical Storm Arlene, which formed on May 15. Tropical Storm Maria was the season's final storm, which dissipated on November 11. The season's strongest storm was Hurricane Lenny, while the costliest and deadliest storm was Hurricane Dennis, which caused over $3 billion (1999 USD) in damages in the Carolinas after causing extensive loss of life in Haiti as a tropical storm. The season was also the first season since 1991 without a tropical cyclone in the month of June, which was unusual considering that a tropical cyclone developed in the month of May in 1999.

Storm Names
The following names were used for systems that reached at least tropical storm intensity during the 1999 Atlantic hurricane season. This list is the same list that was used in the 1993 season with no new names as no names were retired in 1993.

Retirement
In the spring of 1999 at its annual meeting, the World Meteorological Association retired the names Dennis and Lenny from its rotating name lists. They were replaced by Don and Lee for the 2005 season.
