Hurricane Erin is a sprawling Category 4 storm churning in the Atlantic Monday after exploding in strength at a historic rate this weekend. The storm’s enormous footprint is becoming the biggest concern.

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.

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 has been downgraded to a Category 3 hurricane. Hurricane Erin was downgraded to a Category 3 hurricane early Sunday as a tropical storm warning was issued for the Turks and Caicos Islands and winds and heavy rains whipped the Virgin Islands and Puerto Rico.

Forecasters said Erin should begin to slowly weaken as it increased wind shear. However, it's predicted to remain a major hurricane until late next week.

While the category 4 storm is not expected to make landfall on the U.S. east coast, it will have an impact nonetheless. Dangerous high surf and rip currents are expected from Florida to New England throughout the week.
