Tropical Storm Erin is expected to become the Atlantic’s first hurricane of 2025 today, according to the National Hurricane Center. And it could become a Category 4 storm before it’s done. Tropical storm watches remained in effect for parts of the Leeward Islands, which could get brushed by the storm as it passes by to the north over the weekend.

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.
