Hurricane Impact Score
Enter your ZIP code to get a real-time, data-driven risk score (0–100) powered by NHC forecast tracks, FEMA baselines, and coastal proximity analysis.

How the Score Is Calculated
NHC Forecast Track
The engine ingests the official NHC advisory track, cone of uncertainty, and wind radii for each active storm. Your ZIP centroid's distance to the track and cone membership are primary inputs.
Coastal & Elevation Data
Distance to the nearest coastline determines surge eligibility. ZIPs more than 50km inland receive a zero surge score. Coastal proximity also amplifies outage risk.
FEMA NRI Baselines
FEMA's National Risk Index provides historical hurricane, flood, and surge risk scores plus social vulnerability and community resilience data for each ZCTA.
Storm Characteristics
Category, maximum sustained winds, and forward speed all influence sub-scores. Slow-moving storms amplify flood risk; high-category storms amplify wind and surge.
Risk Band Reference
| Band | Score Range | Meaning |
|---|---|---|
| Low | 0–19 | Minimal modeled risk from current storm track |
| Guarded | 20–39 | Some risk possible; monitor storm developments |
| Elevated | 40–59 | Meaningful risk; review preparedness plans |
| High | 60–79 | Significant risk; take preparedness actions now |
| Severe | 80–100 | Extreme modeled risk; follow all official guidance |
