Hurricane Erin, the first major hurricane of the 2025 Atlantic hurricane season, rapidly intensified Friday night, with the storm now reaching Category 5 strength with sustained winds of 160 mph.

Over the weekend, northern portions of the Leeward Islands, the Virgin Islands, and Puerto Rico are expected to receive tropical rain ranging from 2 to 4 inches, with isolated totals up to 6 inches. Flash flooding, landslides and mudslides will be the main concerns over the next several days.

Hurricane Erin has weakened slightly overnight but remains a very strong storm with winds well over 120 mph, making it still a major hurricane. The track remains mostly unchanged. It will start making that northern turn in the next 24 hours.

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.
