Tropical Depression Ten was a tropical depression that did not reach tropical storm status during the 1991 Atlantic hurricane season. The depression developed on October 24 east of the Lesser Antilles. Development in this location is quite atypical for late October, and because of the unfavorable upper wind environment, which is to be expected climatologically during late October, the depression dissipated without incident on October 25.

The depression caused no damage and no deaths.

Meteorological History


The cyclone originated from a tropical wave that emerged off the coast of Africa on October 19. The wave propagated westward across the Atlantic Ocean. By October 23, the wave showed signs of a weak low-level circulation in the central Atlantic Ocean midway between Africa and the Lesser Antilles. At 1200 UTC October 24, convection had become sufficiently organized around the low-level center to designate the formation of a tropical depression. After forming, the depression moved westward, dissipating without incident on October 25 while east of the Lesser Antilles due to strong westerly vertical shear, typical of that part of the Atlantic Ocean during late October.
