Keetch-Byram Soil Moisture Index 

Index Website

Index Description

A drought index specifically designed for fire potential assessment. This index is based on weather station latitude, mean annual precipitation, maximum dry bulb temperature, and the last 24 hours of rainfall. The resulting index relates to the flammability of organic material on the ground. Scores range from 0 to 800 where zero is the point of no moisture deficiency and 800 is the maximum drought.
