Hurricane Erin briefly strengthened into a Category 5 storm. It is not expected to make a direct hit on the U.S. but will create dangerous surf.

Erin is the planet’s second Category 5 storm of 2025, arriving exactly four months after the first one. Cyclone Errol developed off the coast of northwest Australia and rapidly intensified from cat 1 to cat 5 strength in less than 24 hours on April 15–16. Errol then weakened drastically before coming onshore as a tropical low.

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.
