Tropical Storm Hortense was the eighth named storm of the 1990 Atlantic hurricane season. Hortense developed on August 25 in the central Atlantic midway between Africa and the Lesser Antilles. Hortense initially moved west-northwest, but took a turn to the north and then northwest, and dissipated in the central Atlantic on August 31.
Hortense caused no damage and no deaths.

A tropical wave moved off the coast of Africa on August 21. The wave moved westward across the Atlantic Ocean, developed banding features, which indicated a cyclonic circulation, and by 0000 UTC August 25, was organized enough to be designated Tropical Depression Nine while located about 800 miles east of developing Tropical Storm Gustav. The upgrade was made when a ship report indicated that the circulation had reached the surface. The cyclone initially moved west-northwestward. As it did so, upper-level outflow improved, and the system was upgraded to Tropical Storm Hortense at 0600 UTC August 26 while located midway between Africa and the Lesser Antilles. Hortense turned more to the north that same day, due to the influence of an upper-level low. That same upper low also provided shearing over Hortense. As the upper low moved eastward and degenerated into a sharp trough, its influence over Hortense diminished. Consequently, Hortense resumed a northwesterly track. Hortense continued to gradually intensify, and is estimated to have reached its peak intensity of 65 mph and 993 mb at 1200 UTC August 28. Hortense maintained these winds for 24 hours. On August 29, Gustav head become a hurricane, and its upper-level outflow began to shear Hortense, which caused Hortense to weaken to a tropical depression at 0000 UTC August 30. Hortense turned to the north and dissipated at 1200 UTC August 31 while located 700 miles east-northeast of Bermuda.
Lack of Retirement
Because it caused no damage, the name Hortense was not retired in the Spring of 1992 by the World Meteorological Organization. It was used again during the 1996 season, and retired following that season. It was replaced with Hanna for the 2002 season.
