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.

The National Weather Service is warning about high surf and dangerous rip currents as Hurricane Erin continues north track.

Rip currents are the third leading cause of deaths from hurricanes, and they can happen on a sunny day hundreds of miles from the storm.

Hurricane Erin was a Category 4 storm again Monday morning and is expected to grow even larger and stronger, Life-threatening surf and rip currents are likely across the Atlantic coast from Florida to Canada.

Hurricane Erin is forecast to remain well offshore but still bring hazardous currents and possible erosion like previous offshore hurricanes before it.

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

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.
