Hurricane Erin strengthened 85 mph in 24 hours to a 160 mph Category 5 hurricane putting in fourth place for rapidly intensifying storms.

Hurricane Erin exploded in strength to a Category 5 storm in the Caribbean before weakening on Saturday, the National Hurricane Center said.

According to the NHC’s forecast track, the center of Erin is likely to move near or just north of the northern Leeward Islands over the weekend.

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

Tropical Storm Erin formed Monday in the eastern tropical Atlantic Ocean and could become the first hurricane of the 2025 Atlantic season later this week, forecasters say. In the Pacific Ocean, Hurricane Henriette strengthened well away from Hawaii.

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.
