On its own, WHP is not an explicit map of wildfire threat or risk. Areas mapped with higher WHP values represent fuels with a higher probability of experiencing torching, crowning, and other forms of extreme fire behavior under conducive weather conditions, based primarily on landscape conditions at the end of 2014. We present the WHP map in two forms: 1) continuous integer values, and 2) five WHP classes of very low, low, moderate, high, and very high. With these datasets as inputs, we produced an index of WHP for the United States at a 270-meter resolution. with the Large Fire Simulator (FSim), as well as spatial fuels and vegetation data from LANDFIRE 2014 and point locations of past fire occurrence (ca. To create the 2020 version, we built upon spatial datasets of wildfire likelihood and intensity generated for the conterminous U.S. The wildfire hazard potential (WHP) map is a raster geospatial product produced by the USDA Forest Service, Fire Modeling Institute that can help to inform evaluations of wildfire hazard or prioritization of fuels management needs across very large landscapes.Our specific objective with the WHP map is to depict the relative potential for wildfire that would be difficult for suppression resources to contain.
