Hurricane Florence could be one of the largest hurricanes to hit the Carolinas in several years.

The area of tropical storm force winds generated by the storm was 300 miles wide as of Tuesday, according to a tweet from the National Hurricane Center.

Some meteorologists say the storm is more than 500 miles wide. Why the difference?

The National Hurricane Center measures only the area where tropical storm force winds are felt, not the actually width of the cloud formation.

WFLA meteorologists did an unscientific measurement and discovered the width of the storm is the same size as the length of the state of Florida. The measurement was taken to show its massiveness.

No matter where or how you measure Florence, she is a monster storm.

Florence is moving toward the northwest at 16 mph and this general motion, accompanied by a gradual decrease in forward speed, is expected to continue through Saturday, the National Hurricane Center said.

Maximum sustained winds have decreased to near 120 mph with higher gusts. Although slow weakening is expected to begin by late Thursday, Florence is forecast to be an extremely dangerous major hurricane when it nears the U.S. coast late Thursday and Friday.

Hurricane-force winds extend outward up to 70 miles from the center and tropical-storm-force winds now extend outward up to 195 miles, NHC reported.
