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.
