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

Erin will likely cause heavy surf and rip currents along the Eastern Seaboard starting mid-next week, but nothing in the way of rain, surge, or wind.
