Hurricane Erin briefly strengthened into a Category 5 storm. It is not expected to make a direct hit on the U.S. but will create dangerous surf.

The Atlantic’s first hurricane of the season had maximum sustained winds of 160 miles per hour, forecasters said.

Forecasters say Hurricane Erin has exploded into a Category 5 storm in the Atlantic Ocean just north of the Caribbean. The National Hurricane Center says the storm is north of the island of Anguilla with winds of 160 mph.
