Additional strengthening is expected on Monday as Hurricane Erin is forecast to “remain a large and dangerous major hurricane through the middle of this week,” the National Hurricane Center said.

The Atlantic basin includes the northern Atlantic Ocean, Caribbean Sea and Gulf of America, as the Gulf of Mexico is now known in the U.S. per an order from President Trump. NOAA and the National Hurricane Center are now using Gulf of America on its maps and in its advisories.

Hurricane Erin pelted parts of the Caribbean and was forecast to create dangerous surf and rip currents along the U.S. East Coast this week.

The storm will remain a major hurricane through the middle of the week, according to the National Hurricane Center.

Erin has become the first hurricane of the 2025 Atlantic hurricane season. The quick-moving storm expected to become a strong Category 4 storm, with maximum sustained winds of 140 mph within the next 72 hours, according to the latest advisory from the National Hurricane Center.
