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.

As of 7 a.m. CDT Monday, the center of Category 4 Hurricane Erin was located about 115 miles north-northeast of Grand Turk Island, or 890 miles south-southeast of Cape Hatteras, N.C., and was tracking to the northwest at 13 mph.

Rough ocean conditions were forecast for parts of the Virgin Islands, Puerto Rico, Hispaniola and the Turks and Caicos. Life-threatening surf and rip currents were forecast into midweek for the Bahamas, Bermuda, the U.S. East Coast and Canada’s Atlantic coast as Erin turns north and then northeast.
