Monthly Summary

000 ABNT30 KNHC 011110 TWSAT Monthly Tropical Weather Summary NWS National Hurricane Center Miami FL 800 AM EDT Thu Sep 1 2022 For the North Atlantic...Caribbean Sea and the Gulf of Mexico: No tropical cyclones formed in the basin during August. This is quite unusual and is the first time that has occurred since 1997, and is only the third time that has happened since 1950. Based on a 30-year climatology (1991-2020), 3 or 4 named storms typically develop in August, with one or two of them becoming hurricanes. A major hurricane forms in August every 1 to 2 years. No hurricanes have formed in the basin so far this season. 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 has been well below average compared to the long-term (1991-2020) mean. The ACE to date is only 9 percent of the median ACE from the long-term climate period (1991-2020), and is the 2nd-lowest ACE to date in the satellite era (1967-2022). Only 1988 had lower ACE through the end of August. Reports on individual cyclones, when completed, are available at the National Hurricane Center website at www.hurricanes.gov/data/tcr/index.php?season=2022&basin=atl Summary Table Name Dates Max Wind (mph) --------------------------------------------------- TS Alex 5-6 Jun 70 TS Bonnie 1-2 Jul 50 TS Colin 2-3 Jul 40 --------------------------------------------------- * Denotes a storm for which the post-storm analysis is complete. $$ Hurricane Specialist Unit
