ATLANTIC TROPICAL SYSTEMS OF 1992

A total of 69 tropical waves (also known as African and easterly waves ) were counted in the Atlantic basin during the 1992 hurricane season. As was the case in 1991, the waves were, in general, relatively weak. These waves led to the formation of only four tropical depressions in the Atlantic hurricane basin, of which one intensified into a tropica l storm and another intensified into Hurricane Andrew. Andrew was the only 1992 Atlantic hurricane to originate from a tropical wave. There were five additional tropical depressions that were primarily initiate d by systems of nontropical origin. These produced three hurricanes an d one tropical storm. It appears that tropical waves led to the format ion of practically all of the eastern Pacific tropical cyclones in 199 2.
