How do I prepare my car for a hurricane in Florida?

By the Boca Auto Care Editorial Team 路 Reviewed October 28, 2026 路 How we write guides

Short answer

Keep at least half a tank of fuel (or 50-80% charge on an EV) all season, photograph the car and its documents, confirm you carry comprehensive coverage, and park on the highest ground you can reach away from trees. Do the mechanical checks, like tires, wipers and battery, before a cone appears on the map, because shops and parts stores fill up fast.

Get it checked soonThe work takes an afternoon, but it has to happen before a watch is issued. Once a storm is three days out, fuel lines stretch for blocks and repair appointments disappear.

Hurricane season runs from June 1 to November 30. For a car, the storm itself is only part of the risk. Flooded streets, falling limbs, flying debris, days without power at gas stations, and the temptation to drive through standing water afterward cause most of the damage drivers in South Florida deal with.

The good news is that most of this is cheap to prevent. A full set of photos, a known parking plan, a car that starts reliably and a tank that is never near empty cover the majority of it. This guide splits the job into what to do at the start of the season, what to do when a storm is forecast, and what to check before you drive again.

Symptoms

  • A tropical storm or hurricane watch has been issued for Palm Beach County
  • Your tank is under half or your EV is below 50% during hurricane season
  • You are not sure whether your policy covers flood or falling-tree damage
  • Your car is parked under a large tree, near a canal, or in a ground-level lot that floods
  • You are leaving for the summer and the car will sit through the season

Likely causes and what they cost

1. Floodwater entering the cabin or engine

Your comprehensive deductible, commonly $500-$1,000; a flooded car is often declared a total loss

Street flooding in low neighborhoods and parking lots can rise over the door sills in an hour of heavy rain bands. Water in the cabin soaks carpet padding and wiring connectors under the seats. Water pulled into the air intake can hydrolock the engine, bending connecting rods.

The fix: Move the car to higher ground or an upper garage level before the storm. If it floods, do not start it. Have it towed and file a comprehensive claim.

2. Falling limbs and windborne debris

Windshield $300-$1,000, plus $150-$400 for camera calibration on cars with lane-keeping; panel and paint $500-$3,000
common 路 Shop job

Ficus, oaks and coconut palms shed heavy branches and fronds in sustained winds, and loose patio furniture or roof tiles become projectiles. Cars parked next to trees or buildings with loose items take dents, broken glass and crushed roofs.

The fix: Park away from trees, light poles and other people's unsecured belongings. A garage is best. Repairs are dent removal, glass or panel replacement.

3. Running out of fuel when stations go dark

Free, beyond the cost of the fuel
common 路 DIY possible

Pumps need electricity, and stations that lose power or run out of delivery cannot sell fuel for days. Drivers who wait for the watch end up in long lines, which strands people who need to evacuate.

The fix: Keep the tank at least half full from June through November and top off when a storm enters the forecast cone. Store any extra fuel only in approved containers, outdoors, never in a garage attached to the house.

4. Dead battery or weak tires after the storm

Battery test free at most parts stores; replacement $150-$300; tire plug or patch $20-$50
less common 路 DIY possible

A battery that is already three or four years old in Florida heat can fail after days of sitting with the car unused. Tires low on air also make debris-covered roads riskier, and roofing nails are everywhere after a storm.

The fix: Have the battery load-tested before the season, set tire pressure to the door-jamb number, and check that the spare and jack are present and the spare holds air.

5. Saltwater storm surge near the coast

Inspection $100-$200; corrosion damage often leads to a total loss
less common 路 Shop job

Surge along the barrier island and the Intracoastal pushes seawater into streets and garages. Salt is far worse than rain for cars because it keeps corroding electrical connections and brake parts for months after it dries.

The fix: If you live in an evacuation zone, move the car west before the storm or take it with you. A car that sat in salt water should be inspected professionally even if it seems to run.

6. EV or hybrid battery damaged by salt water

Usually handled as a comprehensive total-loss claim
rare 路 Shop job

Salt water that gets into a lithium-ion pack can create short circuits that lead to fires, sometimes days or weeks after the water drains. This was documented after Hurricane Ian on Florida's Gulf Coast.

The fix: If an EV was submerged in salt water, do not charge it and do not park it in or next to a garage. Call your insurer and have it towed to an open area.

Costs are typical South Florida ranges for parts and labor, for budgeting only.

What you can check yourself

  1. 1
    Photograph the car and its papers

    On a clear day, walk around the car taking photos of every panel, the wheels, the interior and the odometer. Photograph the registration and insurance card too, then store the photos in cloud storage. These speed up any claim.

  2. 2
    Read the comprehensive line on your policy

    Flood, falling trees and windborne debris fall under comprehensive, not collision or liability. Check the deductible and whether you have rental coverage. Insurers often pause new policies and coverage changes once a storm threatens, so check in June.

  3. 3
    Set the fuel or charge habit

    The Florida Division of Emergency Management recommends keeping at least half a tank all season, and keeping an EV between 50% and 80% charged depending on the manual.

  4. 4
    Check tires, spare and wipers

    Set pressures cold, look at the spare, and confirm the jack and lug wrench are in the trunk. Replace sun-cracked wiper blades, since outer rain bands bring blinding downpours.

  5. 5
    Pack a small car kit

    Phone charger cable, flashlight, first aid kit, water, a tire inflator, jumper cables or a jump pack, and copies of documents in a zip bag. Keep it in the trunk all season.

  6. 6
    Plan where the car will ride out the storm

    A garage at home is best. If you use a parking structure, choose an interior upper level, never the roof and never the lowest level. Do not block hydrants or private drives with a car left on the street.

When to take it to a shop

  • Water reached the bottom of the doors or the dashboard, or you can see a waterline on the carpet
  • The car was in salt water from storm surge, even briefly
  • Warning lights, airbag light or electrical glitches appear after the storm
  • A tree or debris hit the car and the windshield, roof pillars or lights are damaged
  • The battery is more than three years old and has not been tested before the season

The Florida factor

In Boca Raton the flood risk is not evenly spread. Streets east of Federal Highway and close to the Intracoastal, canal-side neighborhoods west of I-95, and low corners of shopping-center lots tend to hold water first when storm bands stall overhead, even in tropical storms that never become hurricanes. If your usual spot sat under water during any summer downpour, it will be worse in a named storm. Find a fallback spot now, whether that is a friend's garage inland or an upper level of a parking structure.

Coastal Palm Beach County has mandatory evacuation zones, and barrier-island residents in Highland Beach and east Boca are usually first to be ordered out. Taking the car with you is both safer for the car and saves a recovery tow later. Watch county emergency management alerts rather than waiting for a hurricane warning.

Snowbirds who leave in spring should prep the car before they go: half a tank or more, battery tender or disconnected negative cable, parked inside or with a neighbor who can move it. A car left all season in a condo surface lot under a tree, with nobody local to move it, is exactly the setup that turns a near miss into a claim.

Notes for specific makes

  • Tesla: Keep the battery between 50% and 80% during the season as state emergency managers suggest. If a Tesla or any EV was submerged in salt water, NHTSA and fire officials advise keeping it at least 50 feet from buildings and other vehicles and not charging it, because pack fires can start long after the water drains.
  • Toyota: Toyota hybrids keep their high-voltage battery under or behind the rear seat, which sits low in many models. A Prius or RAV4 Hybrid that took water above the floor needs a dealer or hybrid-qualified inspection before anyone tries to start it.

Frequently asked questions

Should I fill my tank or keep it half full?

Keep it at least half full all season, then fill it as soon as a storm enters the forecast cone. A full tank gives you range to evacuate past the lines at stations near I-95 and the Turnpike.

Does car insurance cover hurricane flood damage?

Only comprehensive coverage does. Liability-only or collision-only policies do not pay for flood, falling trees or debris. Homeowner and flood insurance policies do not cover cars.

Can I park in a public garage during the storm?

Some cities and private garages open levels to residents before storms, and some forbid it. Check with the operator, choose an interior upper level, and be ready to collect the car promptly once the all-clear is given.

My car got wet but it starts. Is it fine?

Not necessarily. Water in connectors, the transmission or the axle housings causes failures weeks later. If water rose above the door sill, have it inspected and tell your insurer before driving it daily.

Should I cover my car with a tarp or car cover?

In hurricane winds, a cover acts like a sail and can scratch the paint or tear loose. A garage or an inland spot does far more good.

How to tell if a car has flood damage, and what to do if yours got flooded
The surest signs of flood damage are in places sellers rarely clean: fine silt or a waterline under the seats, in the spare tire well and behind the dash, rust on seat rails and screws under the carpet, and a musty smell masked by heavy air freshener. Run the VIN through NMVTIS and the Florida title check, and never buy a used car in South Florida after a storm season without an independent inspection.
How long does a car battery last in Florida heat?
In South Florida, plan on about two to four years from a typical car battery, compared with five or more in northern states. Heat speeds up the chemical corrosion inside the battery and boils off its water, so the damage builds all summer and often shows up as a sudden no-start in the fall. Testing it every year after year two is the cheapest protection.
Does Florida heat hurt an EV battery?
Yes, but less than many owners fear. Fleet data from Geotab shows EVs in hot climates lose battery capacity about 0.4 percentage points faster per year than those in mild climates, on top of an average of about 2.3 percent a year. Heat also cuts day-to-day range when the A/C runs hard. Charging habits and where you park matter more than the climate itself.
Windshield chip or crack: can it be repaired or does the glass need replacing?
A chip about the size of a quarter or smaller, away from the edges and outside the driver's direct line of sight, can usually be filled with resin for roughly $60-$150. A crack longer than a dollar bill, damage that reaches the edge, or a break through the inner layer of glass means replacement. Get a chip filled within days, because Florida heat cycles turn small chips into long cracks.
Does salt air near the beach rust your car, and how do you stop it?
Yes. Salt carried on ocean air settles on the car, absorbs moisture from Florida humidity and speeds up corrosion wherever bare metal is exposed. Regular fresh-water rinses including the underside, sealing stone chips quickly and keeping drain holes clear prevent most of it. Catching a rust bubble early costs a few hundred dollars, while letting it spread can mean $1,000 or more per panel.
How often should you replace wiper blades in Florida?
In South Florida, plan on new wiper blades about every 6 months, ideally once before the rainy season starts in late May and again in the fall. Sun and heat harden the rubber edge long before it wears out from use, so a blade can look fine and still streak in the first afternoon storm. Florida law also requires wipers to be kept in good working order.
