Hurricane Milton tracker: 'This is a matter of life and death'

As of Wednesday morning, 23% of Florida gas stations were without fuel, according to GasBuddy.

Florida Gov. Ron DeSantis said Wednesday that there’s no fuel shortage but he acknowledged "demand is high and some gas stations have run out."

The Florida Highway Patrol has been escorting fuel tankers to ensure continued supply, especially to ports like Tampa Bay and Manatee, which may face disruptions, he said.

"We've dispatched 1.6 million gallons of diesel and 1.1 million gallons of gasoline," he said.

Fifty-one out of Florida’s 67 counties are under a state of emergency ahead of Hurricane Milton, which has the potential to be one of the most destructive hurricanes on record for west-central Florida.

Gov. Ron DeSantis on Wednesday urged residents in evacuation zones -- particularly in Manatee, Sarasota and Charlotte counties -- to evacuate now.

"The roads are flowing and shelters have space. There’s still time," he said.

About 31,000 people stayed in shelters across Florida Tuesday night and the shelters can accommodate over 200,000 people, according to Kevin Guthrie, executive director of the Florida Division of Emergency Management.

"If you think it’s too late, there is room," Guthrie said. "Your home can be replaced, but you cannot."

DeSantis announced the largest staging of utility workers in U.S. history, with over 50,000 linemen ready to restore power as soon as the storm passes.

Vice President Kamala Harris released a stern warning against engaging in price gouging and fraud in the wake of hurricanes Helene and Milton.

"Those evacuating before Hurricane Milton or recovering from Hurricane Helene should not be subject to illegal price gouging or fraud -- at the pump, airport, or hotel counter," Harris said in a statement. "Any company or individual that tries to exploit Americans in an emergency should know that the Administration is monitoring for allegations of fraud and price gouging and will hold those taking advantage of the situation accountable."

In Pinellas County, which encompasses Clearwater and St. Petersburg on Florida's west coast, residents "are running out of time" to evacuate, county communications director Barbra Hernandez said Wednesday.

"Our goal is to reduce the loss of life. Please get yourself out of harm’s way now," she said. "We don’t want to be plucking people out of the water."

"This will be a knockout," county emergency management director Cathie Perkins added. "Buildings, homes, wiped off foundations. That is unsurvivable."

Mandatory evacuations have been issued in parts of the county. By dusk on Wednesday, all bridges off the peninsula will be closed and first responders will be pulled off the roads due to flooding and high winds, Perkins said.

"You’ll be on your own after that," she warned.
