Seasonal & Sub-Seasonal Tropical Cyclone Forecasts


Colorado State University has issued forecasts of Atlantic basin hurricane activity since 1984. Following the pioneering work of Prof. William Gray, our group continues the long CSU tradition in forecasting with continually improving techniques for predicting tropical cyclone activity powered by new research.

Tropical Weather and Climate Research


We conduct cutting-edge research to advance knowledge and prediction of the weather and climate system. Our research group is focused on improved understanding and prediction of tropical weather, including hurricanes and typhoons, extreme rainfall, and other high impact weather.

Seasonal hurricane forecast team, led by Phil Klotzbach, releases the first forecast for the upcoming 2024 Atlantic Hurricane season.

The 2024 Atlantic hurricane season is predicted to be extremely active. The Atlantic basin Accumulated Cyclone Energy (ACE) and Net Tropical Cyclone (NTC) activity are predicted to be about 170% of their long-term averages (1991-2020). The forecast team is forecasting 23 named storms, 11 hurricanes, 5 major hurricanes, and an Accumulated Cyclone Energy of 210 (the average is 123). Because of the anticipated active season, there is a higher than average probability of major hurricanes making landfall. There is a 62% probability of a major hurricane making landfall along the U.S. coastline and a 66% probability for a major hurricane tracking through the Caribbean.
