The National Weather Service in San Juan reports that Hurricane Erin has strengthened into a powerful Category 5 system as it moves closer to Puerto Rico and the U.S. Virgin Islands, posing multiple hazards to the region over the weekend.
At 11 a.m., the center of Hurricane Erin was located about 235 miles east-northeast of San Juan, Puerto Rico, traveling west at 17 mph. Forecasters said Erin is undergoing rapid intensification and is expected to strengthen further in the coming hours.
The storm’s closest approach is projected for early Sunday morning, when Erin is forecast to pass approximately 120 miles north-northeast of St. Thomas, U.S. Virgin Islands, and about 145 miles north-northeast of San Juan, Puerto Rico.
Authorities warn residents and visitors across Puerto Rico, Vieques, Culebra, and the U.S. Virgin Islands to prepare for significant impacts:
