Hurricane Florence, on track to become the first Category 4 storm to make a direct hit on North Carolina in six decades, howled closer to shore on Tuesday, threatening to unleash deadly pounding surf, days of torrential rain and severe flooding. 

Fierce winds and massive waves are expected to lash the coasts of North and South Carolina and Virginia even before Florence makes landfall by early Friday, bringing a storm surge as much as 13 feet (4 meters), the National Hurricane Center in Miami warned. Catastrophic floods could follow if the storm stalls inland, it said. 

Although Florence was still days from arrival, authorities took extraordinary measures to move people out of harm’s way. More than 1 million residents have been ordered to evacuate from the coastline of the three states, while university campuses, schools and factories were being shuttered. 

The U.S. Coast Guard closed ports in Wilmington and Morehead City, North Carolina and Hampton Roads, Virginia to inbound vessels greater than 500 tons and was requiring vessels of that size to leave if they did not have permission to be in the ports.-
