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 Friday evening, Hurricane Erin had strengthened into a Category 2 storm with maximum sustained winds of up to 100 mph and "expected to rapidly intensify into a major hurricane this weekend," the National Hurricane Center said at 11 p.m. ET.

The National Hurricane Center is tracking two systems in the Atlantic basin, including Invest 98L, which could become a tropical depression before moving onshore in either Mexico or southern Texas.
