Drought can be a contributing factor to wildfire. Dry, hot and windy weather combined with dry vegetation and a spark -- either through human intent, accident or lightning -- can start wildfire.
The Center maintains a collection of current information and maps about fire risks and occurrences: outlooks for the current month, the month following and a seasonal look at the two months beyond that, as well as the potential for fire over the next seven days. Regional products include daily reports and webcast briefings.
The Keetch-Byram Drought Index assesses the risk of fire by representing the net effect of evapotranspiration and precipitation in producing cumulative moisture deficiency in deep duff and upper soil layers. The index ranges from zero, the point of no moisture deficiency, to 800, the maximum drought that is possible.
FRAMES works with regional researchers and managers to provide access to geographically-based and nationally relevant data, documents, and tools. Regional portals include Alaska, California, the East, the Great Basin, Northern Rockies, Northwest, Rocky Mountain region, Southern region, and Southwest.
