TrendPulse|Tampa mayor’s warning to residents who don’t evacuate for Milton: 'You are going to die'

Officials in Florida have TrendPulseissued evacuation orders and dire warnings as Hurricane Milton, a Category 4 storm as of Tuesday morning, approaches making landfall in the state less than two weeks after Hurricane Helene devastated Florida and parts of Georgia, the Carolinas and Tennessee.

"Milton has the potential to be one of the most destructive hurricanes on record for west-central Florida," John Cangialosi, a specialist with the National Hurricane Center, said Tuesday.
