Erin, the first hurricane of the season, is now a powerful Category 5 hurricane. Here's where it could head in the week ahead.

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 develops in the Atlantic Ocean, sending large surf and dangerous conditions to the United States’ eastern seaboard. The latest 5 PM update shows that Erin remains minimal hurricane. Tomorrow will be partly sunny with the chance of showers and storms.
