Hurricane Erin, which briefly intensified into a Category 5 storm Saturday morning, weakened to a Category 3 by the evening as it underwent an eyewall replacement cycle in the Atlantic, forecasters said.

WPBF 25 First Warning meteorologists are tracking Erin, which became a Category 4 hurricane Saturday morning in the eastern tropical Atlantic Ocean. It formed into a tropical storm Monday in the eastern Atlantic Ocean.

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, the first hurricane of the 2025 Atlantic season, is on track to rapidly intensify over the weekend and hit Category 4 strength next week in the open ocean. The latest forecast from the National Hurricane Center calls for Erin to cruise west for the next few days — staying comfortably north of inhabited islands — before hooking north early next week and avoiding direct landfall in the Bahamas or Florida.

The National Hurricane Center is tracking a disturbance in the Gulf near Mexico while watching the path of Tropical Storm Erin.

Hurricane season spans from June 1 to November 30. Here’s what you should know before Erin or any future storm approaches land.

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.
