Hurricane Erin exploded in strength to a Category 5 storm in the Caribbean before weakening on Saturday, the National Hurricane Center said.

The first hurricane of 2025 in the Atlantic continued to track north of Puerto Rico and the Virgin Islands on Sunday morning, hitting those islands with heavy rain and gusty winds. Erin is expected to move away from the islands later today and begin to curve more to the north.

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.

The storm is expected to continue to fluctuate in intensity and could double or even triple in size as it moves north and west, reports said.

Erin is a Category 3 hurricane, the National Hurricane Center said in its 8 p.m. ET update Sunday, with sustained winds of 125 mph and tropical storm-force winds reaching out 205 miles. The storm is expected to continue to fluctuate in intensity and could double or even triple in size as it moves north and west,
