KBDI = 600 - 800: Often associated with more severe drought with increased wildfire occurrence. Lower litter and duff layers actively contribute to fire intensity and will burn actively. KBDI = 400 - 600: Typical of late summer, early fall. Lower litter and duff layers are drying and beginning to contribute to fire intensity. 24218 Cities related to Lee County VA Big Stone Gap Real Estate Pennington WebList of ZIP. KBDI = 200 - 400: Typical of late spring, early growing season. Pennington Gap, VA Weather 20 Today Hourly tenDay Radar Videos. Typical of spring dormant season following winter precipitation. ![]() KBDI = 0 - 200: Soil moisture and large class fuel moistures are high and do not contribute much to fire intensity. The computational steps involve reducing the drought index by the net rain amount and increasing the drought index by a drought factor. Reduction in drought occurs only when rainfall exceeds 0.20 inch (called net rainfall). The inputs for KBDI are weather station latitude, mean annual precipitation, maximum dry bulb temperature, and the last 24 hours of rainfall. At any point along the scale, the index number indicates the amount of net rainfall that is required to reduce the index to zero, or saturation. Zero is the point of no moisture deficiency and 800 is the maximum drought that is possible. At 8 inches of water, the KBDI assumes saturation. It is a closed system ranging from 0 to 800 units and represents a moisture regime from 0 to 8 inches of water through the soil layer. The KBDI attempts to measure the amount of precipitation necessary to return the soil to full field capacity. ![]() It is a continuous index, relating to the flammability of organic material in the ground. Base Reflectivity Doppler Radar for Big Stone Gap VA, providing current static map of storm severity from precipitation levels. It is a number representing the net effect of evapotranspiration and precipitation in producing cumulative moisture deficiency in deep duff and upper soil layers. Keetch and Byram (1968) designed a drought index specifically for fire potential assessment. ![]()
