Quick answer
County hurricane averages miss local wind risk because wind fields, coastal exposure, terrain friction, tree cover, and building-code context vary inside the same county. A county can contain barrier islands, inland towns, and sheltered neighborhoods with different modeled wind histories. The main issue with broad geography is averaging. A county or city summary can be useful for orientation, yet the score changes when the hazard driver is concentrated near specific terrain, coastlines, corridors, land uses, or reporting areas. On HurricaneScore, use the 0 to 10 score as a local-area signal, then read the supporting metrics, confidence, and source notes before moving to a property decision.
The practical workflow is simple: review this article, compare real local pages, read the methodology, and then check an address when a street-address view is needed.

How to interpret the signal
HurricaneScore estimates hurricane risk at neighborhood-scale resolution, which is designed for comparing places more locally than broad county or city summaries. The model pays close attention to wind field structure, track history, landfall exposure, inland decay, and coastal geometry. Those inputs give the score its shape, while the page-level metrics explain which part of the record is driving a particular location.
A careful reading avoids treating the headline score as the whole answer. The score is the entry point. The supporting metrics show severity, frequency, source coverage, and confidence. When those signals agree, the score is easier to compare across nearby places. When they diverge, the article and local page should be read together.
Local examples from current score pages
- ZIP 70397, Terrebonne Parish, LA has a published score of 9.9. Use it as a concrete comparison point when reading nearby pages.
- Terrebonne Parish, LA has a published score of 9.9. Use it as a concrete comparison point when reading nearby pages.
- ZIP 33946, Charlotte County, FL has a published score of 9.7. Use it as a concrete comparison point when reading nearby pages.
- ZIP 33921, Lee County, FL has a published score of 9.7. Use it as a concrete comparison point when reading nearby pages.
These examples use existing score pages from the same site, with the same scoring scale and local page format. They give readers concrete comparison points across ZIPs, cities, counties, and states. A high score in one local page can sit beside lower or differently driven risk in another part of the same state, which is why the supporting metrics matter.
What official sources contribute
- NOAA National Hurricane Center data archive is useful for best-track storm history, storm intensity, and track records. A limitation to keep in mind: post-season records describe observed storms, while local damage still depends on buildings and surroundings.
- NOAA Storm Events Database is useful for local reports of storm impacts and event context. A limitation to keep in mind: reports depend on observation, reporting practice, and local documentation quality.
- NOAA historical hurricane tracks is useful for map-based review of tracks, intensities, and proximity to places. A limitation to keep in mind: track proximity needs wind-field modeling before it becomes a local wind estimate.
Official sources provide the public record behind the analysis. The model turns those records into comparable local signals, while the source notes explain where confidence and interpretation matter. This source-aware reading is especially important for hurricane because public data can vary by reporting density, map update cycles, instrument coverage, or local documentation practice.
How to use confidence, scale, and timing
Hurricane risk changes with geography and time horizon. A score can summarize modeled exposure, but the decision usually depends on the question being asked. A buyer comparing parishes may care about long-run wind probability. An owner preparing for the next season may care about roof details, opening protection, trees, and insurance documentation. A lender or planner may care about consistent comparison across ZIPs and counties. Read the scale first: ZIP, city, county, and state pages answer different questions. Then read the confidence language and source notes. Higher confidence usually means the public record and model inputs point in the same direction. Lower confidence calls for closer review of the underlying indicators and a street-level address check.
Timing also matters. Annual probabilities, historical tracks, and long-run return periods describe different slices of hurricane risk. A recent quiet period can still sit inside a high long-run wind zone, while a recent landfall can raise awareness in a place whose modeled probability remains moderate. Align the metric with the decision before comparing locations.
How this connects to property decisions
A local score helps readers decide where to look more closely. Property-level review asks a narrower question: how does this specific building or parcel respond to the local hazard context? For hurricane, property factors include construction type, roof shape, opening protection, wind mitigation, tree exposure, and distance from open water. These details can change vulnerability, expected damage, or the cost of mitigation.
Use the local score for screening, comparison, and research. Use the address check for the building and parcel context. That sequence creates a clearer audit trail: official source, HurricaneScore methodology, local score page, and property-specific review.
