Hurricane Milton: What should EV owners do before and after storm?

As Hurricane Milton continued swirling toward Florida on Wednesday, many Sunshine State residents in its projected path are bracing for its arrival, including people who own electric vehicles.

The National Hurricane Center (NHC) said Wednesday afternoon that forecasts indicate Milton will arrive onshore Wednesday night along the west-central coast of Florida. It had earlier urged Floridians in its path to quickly finish preparations and evacuations.

Ahead of Milton, one county within the hurricane’s projected path, Hillsborough County, said Monday EV owners in flood zones “should move their vehicles away from flood areas and storm surge” and noted storm surge and flooding can “pose a potential risk to lithium-ion batteries and could lead to fires.” It shared a county webpage about electric vehicle hurricane safety.

The NHC said parts of central and southwestern Florida were expected to see “life-threatening storm surge, damaging winds and flooding rains” when Milton hits the state.

EVs left behind during hurricanes should not be plugged into charging stations or parked in garages because of the potential fire hazard that batteries flooded with saltwater could pose, according to Hillsborough County’s website. It advised keeping electric vehicles 50 feet away from buildings and other cars. 

Florida CFO and State Fire Marshal Jimmy Patronis on Monday also issued a fire safety alert about lithium-ion batteries, EVs and the hurricane.

“After the storm, if you do have an EV that has been flooded by saltwater and it remains in your garage or near your home, please remove it immediately to a safe location so that you can worry about fixing your home instead of rebuilding it due to fire,” he said in part.

EV owners should not operate their vehicles if they have been damaged by flooding, nor should they charge them, Hillsborough County has advised.
