What is storm surge?

Storm surge is sea water that a storm pushes onto land that is normally dry.

Under the NFIP policy, a flood is water covering two or more acres of land that is normally dry, or two or more properties, and one of them is yours. The water has to come from rivers or the sea overflowing, from rain or surface water building up fast, or from mudflow. Storm surge is the sea overflowing. So storm surge is a flood under the NFIP policy.

So which damage does the flood policy pay for? Start with the water.

What storm surge damage is covered?

Water that comes into your home from the ground up is covered. FEMA gives storm surge as its own example, next to heavy rain and a lake or river overflowing.

An NFIP policy pays up to $250,000 for the building and up to $100,000 for what is inside. Contents is a separate coverage: ask for it, or you do not have it.

Land along the shore. Land along the shore that caves in because waves undercut it during a flood can be covered. Gradual erosion is not covered.

The policy has limits in basements and on things outside the home. See the full list of what flood insurance covers.

What about the wind? Read the next part.

Is wind damage covered by flood insurance?

No. The flood policy does not cover wind.

Rain that wind blows into the home is wind damage, not flood. Water that comes in through a roof the storm damaged is wind damage too. A flood policy does not pay for either one.

Those losses belong to your homeowners or windstorm policy. FEMA says those policies may cover damage like wind-driven rain. Check your own policy to see what it pays.

So one storm can mean two claims. Here is how that works.

Do you need two claims after a hurricane?

You may. A hurricane can do wind damage and flood damage to the same home. You may need to file a claim with your flood insurer and another with your homeowners or windstorm insurer, and work with more than one adjuster.

A homeowners policy does not pay for flood water. After Hurricane Helene, insurers reported 10,097 Florida claims closed with no payment because the damage was flood. (Florida Office of Insurance Regulation, data as of June 10, 2025, not audited.)

How big are these storms in Florida? See the last four.

What did the last four big storms cost Florida flood policyholders?

These are NFIP flood claims filed in Florida under each storm's FEMA label. FEMA's data does not say whether the water was surge, rain or a river.

After Hurricane Helene in 2024, Florida owners filed 54,676 NFIP flood claims. Pinellas County alone had 23,452 of them.

Flood claims were not only on the coast. After Hurricane Ian, Orange County, inland, had 872 NFIP flood claims.

Does your flood zone matter?

Your flood zone decides whether your lender requires flood insurance. The price depends on the building and its spot: how high the first floor sits, what it would cost to rebuild, and how often that spot floods. The coverage and deductible you pick count too. See what goes into a Florida flood insurance price.

Zone VE is coastal high-risk land on FEMA's flood map, where waves add to the rising water. Read about Zone VE.

Start with your exact address. Check my address to see the FEMA flood zone for that spot. Then a licensed, independent insurance agent can compare NFIP and private options for your home.

When does a new policy start? Read the timing.

When does a new flood policy start?

Buy before the storm. NFIP policies have a 30-day waiting period. The big exception: if you buy the policy as part of getting, refinancing, extending or renewing a mortgage, coverage starts at closing with no wait.

A flood that was already under way on or before the day you applied and paid in full is not covered.

Private flood policies set their own waiting periods. Read the 30-day wait rules.

Questions Florida owners ask about storm surge and flood insurance

Does flood insurance cover storm surge?

Yes. Storm surge is a flood under the NFIP policy, so flood insurance covers storm surge damage. An NFIP policy pays up to $250,000 for the building and up to $100,000 for contents, if you bought contents.

Does homeowners insurance cover storm surge?

No. A homeowners policy does not cover flood water, and storm surge is flood. A flood policy is the one that covers it.

Is wind damage covered by flood insurance?

No. Flood insurance does not cover wind. Wind damage belongs to your homeowners or windstorm policy. Check that policy to see what it pays.

What if my roof leaked in the hurricane?

Water that comes in through a roof the storm damaged is wind damage, not flood. The flood policy does not pay for it. Check your homeowners or windstorm policy.

Do I need two claims after a hurricane?

You may. One storm can do wind damage and flood damage to the same home. You may need to file one claim with your flood insurer and one with your homeowners or windstorm insurer.

Is erosion covered?

Gradual erosion is not covered. Land along the shore that caves in because waves undercut it during a flood can be covered.

How long before a new flood policy covers a storm?

30 days for a standard NFIP purchase. No wait when the policy is bought as part of making, refinancing, extending or renewing a mortgage. A flood already under way on or before the day you apply and pay in full is not covered.
