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, which briefly intensified into a Category 5 storm Saturday morning, weakened to a Category 3 by the evening as it underwent an eyewall replacement cycle in the Atlantic, forecasters said.

Hurricane Erin on Sunday dropped in intensity overnight, but was expected to regain strength while its path shifted prompting new warnings and watches to be issued by the Bahamas while the National Hurricane Center kept track of two other Atlantic systems.
