Hurricane Erin on Wednesday grew in size as it made its way up into the Atlantic off the U.S. East Coast with tropical-storm conditions forecast to hit North Carolina and dangerous surf left

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 is tracking northwest between the U.S. East Coast and Bermuda, bringing dangerous surf and life-threatening rip currents to Florida and the Carolinas through midweek.
