Shaded areas are FEMA’s mapped flood hazard zones in and around Okaloosa County, Florida. Zoomed out they are simplified; at street level the map switches to FEMA’s exact layer. Tap anywhere to check that spot, or search an address above.
Flash flooding from heavy thunderstorms dominates the flood profile of Okaloosa County, accounting for 65 recorded events and one death over the last 30 years, alongside tropical storms, storm surges, and general floods. Recent impacts include heavy rainfall from thunderstorms in April 2024 and July 2023 that produced widespread areas of flash flooding across the county.
National Flood Insurance Program claims data shows significant risk distributed across multiple zones, led by 4,048 claims in Zone A with an average payout of $49,087 and an average recorded water depth of 10 inches. Zone X accounts for 2,629 claims averaging $49,691 with an average recorded water depth of 11 inches, while Zone V includes 641 claims averaging $52,251 with an average recorded water depth of 12 inches. Additional claims occurred in shaded and unshaded Zone X designations.
Coastal property owners, residents in high-risk Zone A and Zone V areas, and homeowners in moderate-to-low risk Zone X areas should pay the most attention to flood risk, as substantial claims and water depths are recorded across both designated flood zones and unshaded properties.
Summary written from NOAA storm reports and NFIP claims for this county. Not a prediction.
16% of Okaloosa County’s flood insurance claims were on properties rated outside FEMA’s high-risk zones.
5,584 NFIP claims with a recorded rated flood zone, 1978 to date. The zone is the one FEMA used to rate that policy, which may not match today’s map. Source: OpenFEMA NFIP claims.
In flood insurance claims here that reported a flood depth, the average was 10 inches.

Every colour on the map above is a place on this drawing: where the ground sits relative to the flood FEMA plans for.
If a building in Okaloosa County is in a high-risk zone (A or V) and its mortgage comes from a federally regulated or insured lender, or is federally backed, flood insurance is required.
Outside those zones it is optional, and often worth having: from 2014 to 2024 nearly one-third of NFIP claims came from outside the high-risk Special Flood Hazard Area. Since Risk Rating 2.0, NFIP premiums are set for each building, so the only reliable price is a quote: FloodSmart.gov or a local agent.
