Tropical Storm Erin has developed just west of the Cabo Verde Islands, becoming the fifth named storm of the 2025 Atlantic hurricane season. While there are no coastal watches or warnings in effect, the system is forecast to strengthen as it moves west across the open Atlantic.

Tropical Storm Erin formed in the eastern Atlantic Ocean on Monday, forecasters said. The storm could strengthen to become the Atlantic's first hurricane of the season.

Tropical Storm Erin is on the cusp of strengthening into a hurricane, which it is expected to become later this Friday, as it bears down on the northern Caribbean islands.
