Remember I wrote there's usually many days advance warning about hurricanes?
Hurricane Florence is expected to make landfall around 2 pm (EDT) on Friday. It's currently about 200 miles wide. The current maximum sustained winds are 140 mph (220 km/h). It is expected to be a borderline Category 5 hurricane when it makes landfall - winds of about 160 mph (~260 km/h).
The Hurricane Watch zone (where there is a chance of hurricane force winds: 75+ miles per hour) extends from Charleston, South Carolina to north of Virginia Beach, Virginia. That's around 500 miles of coastline.
Coastal counties of South and North Carolina are currently under evacuation orders. The lanes on the Interstate highways leading to the coast have been reversed to help with the evacuation. Businesses are shutting down operations and securing material and equipment. Many hotels 100 miles or more from the expected landfall zone are now full.
It's still looking like it's going to pass to the north of where I live. But, things can change over the next 3 days. And some of the current track projections has it looking like it may do a loop. It's not unheard of for a hurricane to cycle around to the Gulf of Mexico, cross over Florida back to the warm waters of Gulf Stream where it strengthens, and then make another run at the coast. I think Hurricane Andrew from about 15 years ago started at the Florida Keys, zig-zagged it's way up Florida, hitting Atlanta, Georgia, and then eventually dying out when it hit the Appalachian Mountains.
And take a look at this - some of the tracks are showing it might come near you.
