Currently, it is not affecting any land masses, but the NHC said the northern Leeward Islands, Virgin Islands and Puerto Rico should monitor the storm.

Erin is the fifth named storm of the Atlantic hurricane season, which runs from June 1 to Nov. 30. It's the first to become a hurricane.

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.

Erin became the first hurricane of the 2025 Atlantic season on Friday and was expected to continue strengthening, forecasters said.

Erin has strengthened into a hurricane as it approaches Puerto Rico and the Virgin Islands, bringing heavy rains that could cause flooding and landslides.

Officials in the northern Caribbean are warning of heavy rains and dangerous swells as Tropical Storm Erin approaches the region.

The National Hurricane Center said the storm has winds of 50 miles per hour, and is expected to become a major hurricane by the weekend.

As of Wednesday afternoon, Tropical Storm Erin is churning in the Atlantic Ocean and moving toward the Caribbean, likely to become the season’s first hurricane, a storm with sustained winds above 74 miles per hour.
