Hurricane Erin, the first major hurricane of the 2025 Atlantic hurricane season, rapidly intensified Friday night, with the storm now reaching Category 5 strength with sustained winds of 160 mph.

Hurricane Erin has weakened slightly overnight but remains a very strong storm with winds well over 120 mph, making it still a major hurricane. The track remains mostly unchanged. It will start making that northern turn in the next 24 hours.

Hurricane Erin weakened slightly on Sunday during an eyewall replacement cycle but will grow larger and stir up surf along the U.S. east coast.

Green flags lined Fort Lauderdale Beach on Sunday, signaling calm conditions. But as Hurricane Erin approaches, officials say things could change in the coming days.

Hurricane Erin is forecast to remain well offshore but still bring hazardous currents and possible erosion like previous offshore hurricanes before it.

5 p.m. Update: Erin is now organizing and strengthening over the Central Atlantic. Erin is expected to become at least a Catgory 3 hurricane but missing Puerto Rico to the north and staying well east of Florida. It is expected to reach Jacksonville’s latitude about early Wednesday, resulting in some rough seas and surf at area beaches next week.
