Floridians should prepare for at least Category 3 hurricane: DeSantis

Floridians should be prepared for at least a Category 3 hurricane, Gov. Ron DeSantis warned Monday.

"This is going to be a major impact," DeSantis said at a press briefing.

DeSantis said evacuation orders will be issued for low areas along the coast.

If "you're told to evacuate, you do not need to drive hundreds of miles. You do not need to leave the state of Florida," the governor noted. "You basically need to go to higher ground in almost every instance. You can go tens of miles to a shelter, to a hotel, to a friend's house, whatever works for you, and you'll be able to ride out the storm."
