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.

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 has intensified to a Category Four Hurricane as it makes its way toward the East Coast of the United States.

Hurricane Erin strengthened into a Category 4 storm on Saturday morning, making it the first major hurricane of the 2025 Atlantic season.
