How is wildfire risk assessed?

The USFS WHP model combines fire likelihood (historical ignition patterns, weather) with fire intensity potential (vegetation type, topography) to produce a hazard classification from Very Low to Very High.

Does this account for fire prevention measures?

The WHP reflects natural wildfire hazard potential. It does not account for local fire prevention measures, building codes, or firefighting resources.

How often is wildfire data updated?

The USFS updates the WHP dataset every 2-3 years as new vegetation mapping and fire history data become available.

Wildfire Risk by ZIP Code

Wildfire risk is based on the US Forest Service Wildfire Hazard Potential (WHP) dataset, which maps fire likelihood and intensity using vegetation, weather, topography, and historical fire data. The 5-class system (Very Low to Very High) is mapped to our 0-100 scale.
