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, now a Category 3 storm, is expected to strengthen and become a Category 4 hurricane, with maximum sustained winds of 150-mph.

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