 Tropical cyclogenesis in the 1992 Atlantic hurricane season began with the development of Subtropical Storm One on April 21 . However , over the next three months , minimal activity occurred , with only two depressions developing , one in June and the other in July . Although wind shear was relatively weak in August , only one tropical cyclone occurred in that month . However , that one tropical cyclone , Hurricane Andrew , was the strongest and costliest of the season . Though September is the climatological peak of hurricane season , an increase in wind shear prevented tropical cyclogenesis in the first half of the month . After September 16 , however , five tropical cyclones developed in a span of nine days , from September 17 to 26 . Thereafter , activity abruptly halted , and only one tropical cyclone developed in October , Hurricane Frances . By October 27 , Frances became extratropical , which was more than a month before the official end of the season on November 30 .
