Triple-I: 2024 Atlantic Hurricane Season Forecast to be ‘Very Active’


For immediate release

ST. JOHNS, Fla., April 4, 2024 -- A very active tropical cyclone season is projected for 2024 in the Atlantic basin, according to a forecast released today by Colorado State University’s (CSU) Department of Atmospheric Science.


Led by senior research scientist Phil Klotzbach, Ph.D., also a non-resident scholar at the Insurance Information Institute (Triple-I), the CSU Tropical Meteorology Project forecasts 23 named storms, 11 hurricanes and five major hurricanes during the 2024 season, which starts on June 1 and continues through Nov. 30. A typical Atlantic season has 14 named storms, seven hurricanes and three major hurricanes.


The 2023 season produced 20 named storms and seven hurricanes. Three reached major hurricane intensity. Major hurricanes are defined as those with wind speeds reaching Category 3, 4 or 5 on the Saffir-Simpson Hurricane Wind Scale.


One hurricane and two tropical storms made continental U.S. landfalls last year. Category 3 Hurricane Idalia struck Florida’s Big Bend region near Keaton Beach on Aug. 30 with wind speeds of 115 mph. It was the third hurricane, and second major hurricane, to make a Florida landfall over the past two seasons. Idalia caused storm surge inundation of 7 to 12 feet and widespread flooding in Florida and throughout the Southeast. 


Other named storms that made U.S. landfalls in 2023 included Tropical Storm Harold, which made landfall near South Padre Island, Texas, on Aug. 22; and Tropical Storm Ophelia, which made landfall near Emerald Isle, N.C., on Sept. 23.


“The widespread damage incurred from Idalia last year highlighted the importance of being financially protected from catastrophic losses and that includes having adequate levels of property insurance and flood coverage. Beyond Florida, we saw significant impacts from Idalia in southern Georgia and the Carolinas. All it takes is one storm to make it an active season for you and your family, so it is time to prepare as the 2024 Atlantic hurricane season’s start nears,” said Sean Kevelighan, CEO, Triple-I.


Kevelighan added, “This is an ideal time for homeowners and business owners to review their policies with an insurance professional to ensure they have the right amount and types of coverage, allowing them to be financially protected for property damage caused by either wind or water. That also means exploring whether they need flood coverage, which is not part of a standard homeowners, condo, renters or business insurance policy. Additionally, homeowners can make their residences more resilient to windstorms and torrential rain by installing roof tie-downs and a good drainage system.”


Flood policies are offered through FEMA’s National Flood Insurance Program (NFIP) and dozens of private insurers. The installation of a wind-rated garage door and storm shutters also boost a home’s resilience to a hurricane’s damaging winds, according to the Triple-I, and can potentially generate savings on a homeowner’s insurance premium.


Private-passenger vehicles damaged or destroyed by either wind or flooding are covered under the optional comprehensive portion of an auto insurance policy.


Triple-I offers numerous hurricane season preparedness tips. These include:

  • Developing a photo/video inventory of your possessions and your home’s exterior, which will ease the claims-filing process.
  • Preparing a hurricane emergency kit with a minimum two-week supply of essential items, such as drinking water, non-perishable food, medications, flashlights, and extra batteries.
  • Creating an evacuation plan well before any storm warnings are issued.


“We anticipate a well above-average probability for major hurricanes making landfall along the continental United States coastline and in the Caribbean this season,” Klotzbach said.


Klotzbach added, “Current El Niño conditions are likely to transition to La Niña conditions this summer/fall, leading to hurricane-favorable wind shear conditions. Sea surface temperatures in the eastern and central Atlantic are currently at record warm levels and are anticipated to remain well above average for the upcoming hurricane season. A warmer-than-normal tropical Atlantic provides a more conducive dynamic and thermodynamic environment for hurricane formation and intensification. Our forecast is of above-normal confidence for an early April outlook.”


CSU’s 2024 forecast calls for a 62% percent chance of a major hurricane making a mainland U.S. landfall (average from 1880 to 2020 is 43%), 34% for the U.S. East Coast including the Florida Peninsula (versus 21% historical average), and 42% percent for the Gulf Coast from the Florida Panhandle westward to Brownsville, Texas (versus 27% historical average).
