SAN JUAN, Puerto Rico — 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 National Hurricane Center said.
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.
Hurricane Erin is set to sweep by Puerto Rico this weekend, bringing with it high winds and heavy rains. Luckily, it’s not set to make landfall, but the close call could still pose problems for the island’s increasingly fragile power grid.
