About hurricane risk
Hurricane risk is concentrated along the Atlantic and Gulf coasts, where the 18 coastal states contain roughly 60% of the US population and the majority of its high-value real estate. NOAA's Storm Events database records the historical events that drive the FEMA NRI hurricane percentile; the National Hurricane Center publishes the live forecasts during season (June through November).
Two risks sit under the hurricane label: wind and surge. They have separate insurance products (wind is typically covered by the homeowners policy, surge and flood are not) and separate mitigation paths. A wind mitigation inspection — required in Florida, common elsewhere — can reduce the wind portion of a homeowner's premium by 20 to 40 percent, depending on roof shape, age, and attachment. The risk that drives most catastrophic loss, however, is storm surge: in major hurricanes, surge depth can exceed 15 feet in coastal counties and penetrate several miles inland.
Hurricane is the hazard where the state-level insurance market matters most. Florida, Louisiana, and a growing list of other coastal states have seen admitted carriers withdraw and residual markets (Citizens, FAIR Plan) swell. Buyers in coastal counties should expect to interact with multiple carrier types and to budget for both wind and flood coverage as separate line items.
What signals a hurricane-exposed parcel
The strongest signal of hurricane exposure is the FEMA NRI hurricane percentile, which captures the historical frequency and severity of named-storm impact at the county level. Coastal counties in FL, LA, TX, NC, and SC dominate the high-percentile end. The NOAA Storm Events database is the source for event-by-event history. For wind, the dominant construction signals are roof shape (hip roofs outperform gable) and roof age (under 10 years is the typical carrier threshold).
Risk Bands Explained
Category 3–5 exposure zone
Coastal areas with high historical wind and surge frequency
Category 1–2 exposure zone
Elevated risk — wind mitigation and comprehensive coverage required
Inland / low exposure
Reduced hurricane risk but wind and flood exposure still possible
Buyer Action Checklist
- 01
Request wind mitigation inspection report — it can reduce insurance premiums by 20–40%
- 02
Check storm surge maps separately from wind risk maps
- 03
Verify roof age and construction — hip roofs and newer materials reduce risk
- 04
Model combined wind and flood insurance costs before committing to a budget

Hurricane Risk FAQ
Do I need both wind and flood insurance in a hurricane zone?
Yes. Standard homeowners policies cover wind in most states (Florida is the major exception, where Citizens and other wind-only carriers exist). Flood is excluded from standard homeowners and must be purchased as a separate NFIP or private flood policy. Buyers in coastal counties should budget for both line items.
How is hurricane risk different from tropical storm risk?
Tropical storms are below hurricane strength (sustained winds under 74 mph) and can still cause significant rainfall flooding, but the structural risk to a well-built home is materially lower. The Risk Before Buy hurricane score uses the FEMA NRI hurricane percentile, which captures both named-storm and major-hurricane exposure at the county level.
What is a wind mitigation inspection?
A licensed inspector evaluates the roof shape, age, attachment, and secondary water resistance features of a home. In Florida and a growing number of other coastal states, the resulting form (OIR-B1-1802 in FL) qualifies the homeowner for premium credits of 20 to 40 percent on the wind portion of the policy. It is one of the highest-ROI inspections a buyer in a hurricane-exposed region can request.
