After exploding in strength at a historic rate this weekend, Hurricane Erin is now a sprawling Category 4 storm churning in the Atlantic. The storm’s enormous footprint is becoming the biggest concern as it threatens to drive life-threatening rip currents and towering waves toward the eastern US coastline and Bermuda.

Hurricane Erin pelted parts of the Caribbean and was forecast to create dangerous surf and rip currents along the U.S. East Coast this week.

Hurricane Erin restrengthened back into a Category 4 storm Sunday night as it churned over the Atlantic Ocean north of the Caribbean.Erin, the first Atlantic hurricane of 2025, exploded to Category 5 on Saturday before weakening to a Category 3 storm early Sunday morning and regaining strength later in the day.

Hurricane Erin has turned into a Category 4 storm, rapidly powering up over the course of 24 hours, the National Hurricane Center said.

After briefly weakening, Hurricane Erin has re-intensified into a Category 4 hurricane with sustained winds of 130 mph, according to the National Hurricane Center.
