As of Saturday morning, Hurricane Erin had strengthened into a Category 5 storm with maximum sustained winds of up to 160 mph, the National Hurricane Center said. The storm is currently located about 105 miles north of Anguilla and about 235 miles east-northeast of San Juan, Puerto Rico. Erin is moving west at 17 mph.

The Atlantic basin includes the northern Atlantic Ocean, Caribbean Sea and Gulf of America, as the Gulf of Mexico is now known in the U.S. per an order from President Trump. NOAA and the National Hurricane Center are now using Gulf of America on its maps and in its advisories.

Heavy rains were forecast to start late Friday in Antigua and Barbuda, the U.S. and British Virgin Islands and southern and eastern Puerto Rico.
