Hurricane Erin, the first of the 2025 Atlantic season, is forecast to become a major storm this weekend, bringing heavy rain, flooding risk, and dangerous surf to parts of the Caribbean and western Atlantic.

Erin’s sustained winds increased to 70 mph, just 4 mph shy of hurricane strength. The hurricane center said Erin should continue to strengthen through the weekend, when it should be moving near or north of the Leeward Islands, according to the official forecast path.
