November 20th 2025 Press Release

"FORT COLLINS, COLORADO – The 2025 Atlantic hurricane season ended up an above-normal season, as measured by the number of major hurricanes and Accumulated Cyclone Energy (ACE). This activity was well forecast by Colorado State University’s July and August updates and slightly over-forecast with our April and June forecasts. The season had an unusual distribution of tropical cyclone activity, with 13 named storms, 5 hurricanes and 4 major hurricanes. The 1991–2020 average season has 14 named storms, 7 hurricanes and 3 major hurricanes. All four major hurricanes reached at least Category 4 intensity, with three reaching Category 5 intensity (Erin, Humberto and Melissa). The season was benign for continental US impacts, with only one tropical storm (Chantal) making landfall, costing ~$500 million USD in damage. However, Hurricane Melissa caused devastation when it made landfall as a Category 5 hurricane in Jamaica, with preliminary estimates of $6–$7 billion USD in damage. The storm also caused extensivedam age in Cuba and Hispaniola."
