Expires:No;;965023 ABNT30 KNHC 010300 TWSAT Monthly Tropical Weather Summary NWS National Hurricane Center Miami FL 1000 PM EST Sat Nov 30 2024 For the North Atlantic...Caribbean Sea and the Gulf of Mexico: Tropical cyclone activity this November was above average in terms of the number of named storms, hurricanes, and major hurricanes in the Atlantic basin. Three named storms formed during the month, including one (Rafael) that became a major hurricane. Based on a 30-year climatology (1991-2020), a tropical storm forms in November once every year or two, and a hurricane forms once every two years. Rafael strengthened into a hurricane while passing near Jamaica and the Cayman Islands before making landfall in western Cuba as a category 3 hurricane. Elsewhere, Patty brought tropical storm conditions to portions of the Azores. Sara meandered near the coast of Honduras before making landfall as a tropical storm in Belize. Overall, the 2024 Atlantic hurricane season had above-normal activity in terms of the number of named storms, hurricanes, and major hurricanes. In 2024, there were 18 named storms that formed in the Atlantic basin, of which 11 became hurricanes and 5 strengthened into major hurricanes (category 3 or higher on the Saffir-Simpson Hurricane Wind Scale). These numbers are greater than the long-term (1991-2020) averages of 14 named storms, 7 hurricanes, and 3 major hurricanes. In terms of Accumulated Cyclone Energy (ACE), which measures the strength and duration of tropical storms and hurricanes, activity in the basin in 2024 was about 34 percent above the long-term (1991-2020) average.
