You can also check the National Hurricane Center website for updates leading up to your trip - they usually name a hurricane 36 to 48 hours in advance.
As of 5 a.m. EDT (0900g) it was centered about 205 miles (325 kilometers) east-southeast of Wilmington, North Carolina and about 250 miles (450 kilometers) east-southeast of Myrtle Beach, South Carolina, moving northwest at 15 mph (24 kph).
According to the National Hurricane Center's "hurricane hunter" airplane, waves of 83-feet were measured near the eye of Florence on Monday. This general motion, accompanied by a further decrease in forward speed, is expected to continue through today. That forecast area also includes part of southwest Virginia. More than four million people live in areas at most risk from the storm, which the Joint Typhoon Warning Center in Hawaii categorised as a super typhoon with powerful winds and gusts. It then will move near or over the coast of southern North Carolina and eastern SC in the hurricane warning area later Thursday and Friday.
The Miami-based center says the center of the eye moved ashore with top sustained winds of 90 miles per hour (150 kph), making Florence a Category 1 hurricane in terms of wind intensity.
"We expected it to strengthen and then as it approached the coast to weaken somewhat", Abrams says.
The storm's minimum central pressure is 955 MB or 28.20 inches.
According to the NHC's forecast discussion at 12 p.m. on September 13: "The subtropical ridge to the northeast and east of Florence is now well-established between Bermuda and the USA mid-Atlantic region and extends westward into Virginia and the central Appalachians".
Storm surge is deadly.
President Trump spoke with the senators of North Carolina and SC, telling them they have the full support of the federal government and the feds will be there to help with anything their states may need.
The centre issued a public advisory with a summary of watches and warnings in effect for several areas.
According to NHC: "A Hurricane Warning means that hurricane conditions are expected somewhere within the warning area". "There is probably not a county or a person that will not be affected in some way by this very massive and violent storm". Tropical storm-force winds are predicted to arrive by late Thursday morning or early afternoon.
A new tool created by the NHC helps visualize how devastating the storm surge could be.
Storm to be "exceptionally bad news" if it hovers offshore Usually when a storm approaches the coast, forecasters can tell with ever-increasing accuracy who will get walloped. This is a life-threatening situation. Hurricane Helene and Subtropical Storm Joyce were off in the Atlantic, posing no threat.
