000 ABNT30 KNHC 011156 TWSAT Monthly Tropical Weather Summary NWS National Hurricane Center Miami FL 800 AM EDT Sat Oct 1 2022 For the North Atlantic...Caribbean Sea and the Gulf of Mexico: Tropical cyclone activity in the Atlantic basin during September was above normal in terms of the number of named storms, hurricanes, and major hurricanes. Six named storms formed in the basin during September with four of those becoming hurricanes, and two becoming major hurricanes. One unnamed tropical depression also formed. Based on a 30-year climatology (1991-2020), four or five named storms typically develop in September, with three of them becoming hurricanes, and one of those becoming a major hurricane. Fiona made landfall in Puerto Rico, the Dominican Republic, and the Turks and Caicos Islands as a hurricane, and affected Atlantic Canada as a powerful post-tropical cyclone. Ian made two landfalls as a major hurricane, one in western Cuba and one along the southwest coast of Florida, and another landfall as a hurricane in South Carolina. In terms of Accumulated Cyclone Energy (ACE), which measures the strength and duration of tropical storms and hurricanes, activity in the basin so far in 2022 is slightly below average. Despite the slow start to the season, September activity increased ACE to 85 percent of the long-term median value through the end of the month.
