Hurricane Erin formed in the Atlantic Aug. 15 and rapidly strengthened to a catastrophic Category 5 storm with 160 mph winds on Saturday, Aug. 16, according to the National Hurricane Center. Erin is the first hurricane of the 2025 Atlantic hurricane season.

A southward shift in Erin’s track has led to an increase in risk for the northern Caribbean Islands, though a direct hit in the United States is unlikely.
