<\/p>\nThe team of hurricane researchers at Colorado State University shaved off a storm from its original Atlantic hurricane season forecast, and now sees a \u201cslightly\u201d above normal season.<\/p>\n
High levels of observed Caribbean wind shear, which break up storms, is the primary reason for the reduction in expected named storms to 16, hurricanes to eight, and major hurricanes to three.<\/p>\n
CSU in its last two forecasts of the hurricane season called for 17 named storms and nine hurricanes \u2013 with four major hurricanes of at least Category 3 (111 mph or more) strength.<\/p>\n
The average hurricane season has 14 named storms, seven hurricanes and three major hurricanes. Last year\u2019s record-breaking season included 18 named storms, 11 hurricanes and five major hurricanes.<\/p>\n

The skill of CSU\u2019s forecast updates increases as the peak of the Atlantic hurricane season approaches.\u201d<\/p>\n CSU\u2019s models put a 48% probability of a major Atlantic hurricane hitting the U.S. in 2025. The average probability is 43%. The probabilities for a Gulf Coast or East Coast landfall in 2025 are 31% and 25%, respectively.<\/p>\n Phil Klotzbach, senior research scientist in CSU\u2019s Department of Atmospheric Science, said conditions right now<\/a> are similar to the 2001, 2008, 2011, and 2021 hurricane seasons. Hurricane Ike (2008) and Hurricane Ida (2021) stand out in these years. Both are among the costliest hurricanes to private insurers in history.<\/p>\n Another update to CSU\u2019s forecast will be issued on Aug. 6.<\/p>\n Topics<\/span> Catastrophe<\/a> Natural Disasters<\/a> Trends<\/a> Hurricane<\/a> <\/p>\n<\/p><\/div>\n Was this article valuable?<\/p>\n<\/p><\/div>\n![](\"https:\/\/www.insurancejournal.com\/app\/uploads\/2025\/07\/Costliest-Hurricanes-July-2025-Aon-TripleI.png\")
