Erin is the planet’s second Category 5 storm of 2025, arriving exactly four months after the first one.

Errol then weakened drastically before coming onshore as a tropical low.

Tropical Storm Erin is continuing to move west and is forecast to become a hurricane later this week, according to the National Hurricane Center.

Erin was expected to strengthen into a hurricane on Friday and forecast to become a major Category 3 storm late this weekend.
