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 exploded in strength to a Category 5 storm in the Caribbean on Saturday, rapidly powering up from a tropical storm in a single day, the U.S. National Hurricane Center (NHC) said.

This type of explosive strengthening is happening more frequently as planet-warming pollution tips the scales toward hotter oceans that fuel powerful storms.
