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.

Hurricane Erin is rapidly intensifying as it tracks above the northeastern Caribbean Saturday, churning up rough surf and sending rain and gusty winds to islands south of its path.

Officials stressed that even without landfall, Erin brings several risks.
