SAN JUAN, Puerto Rico (AP) — Erin strengthened into a powerful Category 4 hurricane in the Caribbean on Saturday and continues to intensify, the National Hurricane Center said. The storm is 150 miles northeast of Anguilla with maximum sustained winds of 145 mph. It is moving west-northwest at 20 mph (31 kph).

"The good news is that Dexter is moving away from the U.S., and expected to become ripped apart by stronger wind shear," said Weather.com's Jonathan Belles. "However, we could still see high surf and possible rip currents along the East Coast for the next several days."
