Additional strengthening is expected as the storm is forecast to “remain a large and dangerous major hurricane through the middle of this week,” the National Hurricane Center said.

Tracking Hurricane Erin, the first named storm of the Atlantic hurricane season, which weakened to a Category 3 storm early Sunday.

Forecasters say Erin may fluctuate in intensity but is likely to remain a major hurricane through the middle of the week. Residents in the northwestern Bahamas, Bermuda, and along the southeastern U.S. coast are being urged to monitor the storm closely.

Erin strengthened again Monday as it began pelting part of the Caribbean with rain and wind before it’s expected to create dangerous surf and rip currents along the U.S. East Coast this week.

Hurricane Erin was a Category 4 storm again Monday morning and is expected to grow even larger and stronger, according to the latest advisory from the National Hurricane Center. Although Erin is forecast to move north between the U.S. and Bermuda, life-threatening surf and rip currents are likely across the Atlantic coast from Florida to Canada.

Erin is officially the first hurricane of the 2025 season. Maximum sustained winds of 75 mph were recorded Friday, Aug. 15, as the storm continues to move west-northwest near 18 mph. Wind speeds are expected to strengthen, and the hurricane will likely become a major hurricane over the weekend.
