There’s a hurricane building in the Atlantic — and according to the latest forecast, it’s headed straight for your state. Is it too late to get flood insurance?

Most likely, the answer is yes. There’s usually a waiting period of 10 to 30 days between when you buy a flood insurance policy and when the coverage takes effect, depending on where you get your coverage. However, there are a few situations in which you can get immediate flood insurance.

Federal flood insurance waiting period

When you buy a policy through the National Flood Insurance Program, coverage generally starts 30 days from the purchase date. If flooding occurs during the blackout period, your policy won’t pay to fix damage to your home or belongings.

However, the following exceptions apply to the 30-day NFIP waiting period, according to the Federal Emergency Management Agency.


There’s no waiting period if you buy flood insurance in conjunction with a mortgage loan. This rule applies to getting a new mortgage or to increasing, extending or renewing your loan. (Mortgage lenders generally require flood insurance for homeowners who live in high-risk flood zones.)

Renewing existing flood insurance

If you already have flood insurance and decide to update your coverage at renewal time, the new limits will take effect once your old policy expires, with no waiting period.


If your house wasn’t located in one of FEMA’s Special Flood Hazard Areas when you first moved in, you probably didn’t buy flood insurance. But what if FEMA redoes its maps and your home is now in a high-risk zone? You can get a policy with only a one-day waiting period as long as you buy within 13 months of the remapping.

Visit FEMA’s Flood Map Service Center to find out if your home is in a high-risk flood zone.


After a wildfire, the risk of flooding increases because charred vegetation leaves the ground unable to absorb rainfall. If your home is affected by flooding on burned federal land and you buy an NFIP policy within 60 days of the date the fire was contained, there may be no waiting period for coverage.

Private flood insurance waiting period

Depending on the company, your waiting period might be shorter — around 10 to 15 days — if you buy private flood insurance. But as with the NFIP, there may be some exceptions. For instance, if you’re getting a policy as part of the mortgage closing process, there may be no waiting period.

You may also be able to skip the waiting period if you’re getting private flood insurance when your NFIP policy is set to renew.

Not all states and communities have private flood insurance providers, so ask your home insurer or agent about options in your area.

Last-minute flood insurance for your car

Flood insurance doesn’t extend to your vehicle. If your car suffers flood damage, comprehensive car insurance pays for repairs.

Note that comprehensive coverage isn’t required by law, though it may be required by your lender if you borrowed money to buy your vehicle. If you have only the state-mandated minimum insurance on your car, it wouldn’t be covered in the case of a flood.

Not sure what coverage you have? Check the declarations page of your auto policy or call your insurer.

Car insurance companies generally won’t sell new coverage if your area is under a storm watch. If that hasn’t happened yet, ask your insurer about adding comprehensive coverage to your policy. Provided you're able to get the coverage, there won't be a waiting period.
