EXTENDED RANGE FORECAST OF ATLANTIC SEASONAL HURRICANE
ACTIVITY AND LANDFALL STRIKE PROBABILITY FOR 2025
We have maintained our forecast for an above-normal 2025 Atlantic basin hurricane
season. The tropical Pacific currently is characterized by ENSO neutral conditions, and
we anticipate these to persist through the hurricane season. Sea surface temperatures
across the eastern and central Atlantic are warmer than normal, but not as warm as they
were last year at this time. A warmer-than-normal tropical Atlantic combined with likely
ENSO neutral conditions typically provides a more conducive dynamic and
thermodynamic environment for hurricane formation and intensification. We anticipate
an above-average probability for major hurricanes making landfall along the continental
United States coastline and in the Caribbean. As with all hurricane seasons, coastal
residents are reminded that it only takes one hurricane making landfall to make it an
active season. Thorough preparations should be made every season, regardless of
predicted activity.
