The 2025 Atlantic hurricane season is expected to be more active than usual, with 17 named storms, nine hurricanes, and four major hurricanes, according to a new forecast from Colorado State University (CSU) in partnership with the Insurance Information Institute (Triple-I).
Led by CSU’s senior research scientist Phil Klotzbach, Ph.D., a non-resident scholar at Triple-I, the forecast cites warmer-than-normal Atlantic waters and the potential for neutral or weak La Niña conditions as key drivers of an above-average season.
A typical Atlantic hurricane season averages 14 named storms, seven hurricanes, and three major hurricanes.
“This is an ideal time for homeowners and business owners to review their insurance policies with an insurance professional,” said Sean Kevelighan, CEO of Triple-I. “Having the right types and amounts of coverage is critical to being financially protected from storm damage.”
The 2024 season produced 18 named storms and 11 hurricanes, five of which reached major hurricane strength. Notable landfalls included Hurricanes Debby, Helene, and Milton in Florida, with Helene—a Category 4 storm—causing widespread damage across multiple southeastern states.
Triple-I emphasized that severe hurricane impacts can extend far beyond the initial landfall. The group encourages people to not only secure adequate wind and flood insurance—since flood coverage is not included in standard homeowners or business policies—but also to make physical improvements such as installing roof tie-downs, storm shutters, and wind-rated garage doors.
CSU’s forecast also includes updated landfall probabilities:
Triple-I urges residents in hurricane-prone areas to prepare early by developing emergency plans, documenting property, and assembling disaster supply kits.
