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 has strengthened to a Category 4 hurricane as it threatens to bring life-threatening surf and rip currents to the eastern coast of the United States. The rains caused by the storm are already beginning to hit the south-eastern Bahamas, and the Turk and Caicos Islands, where a tropical storm warning is in effect.

The Outer Banks in North Carolina are under evacuation warning as Hurricane Erin whips up potentially 20-foot high waves and flooding along the east coast.

Hurricane Erin was a Category 4 storm again Monday morning and is expected to grow even larger and stronger, according to the latest advisory from the National Hurricane Center. Although Erin is forecast to move north between the U.S. and Bermuda, life-threatening surf and rip currents are likely across the Atlantic coast from Florida to Canada.

Early Monday, the storm strengthened into a Category 4 hurricane, packing maximum sustained winds of 130 mph as it approached the southeastern Bahamas, the NHC reported.

After exploding in strength at a historic rate this weekend, Hurricane Erin is now a sprawling Category 4 storm churning in the Atlantic. The storm’s enormous footprint is becoming the biggest concern as it threatens to drive life-threatening rip currents and towering waves toward the eastern US coastline and Bermuda.

Forecasters expect Hurricane Erin, one of the fastest rapidly intensifying storms in history, to bring flooding and dangerous currents as the Category 4 hurricane travels to the U.S. East Coast this week.
