The 100-hr Dead Fuel Moisture map displays the % moisture content (dry-weight basis) of 100-hour dead fuels as calculated by a calibrated version of the Nelson dead fuel moisture model. Calculated values can range from 1% to 40%. 100-hour fuels include roundwood with diameters of 1-3" as well as organic materials beneath the surface at roughly 1-4" depths. 100-hour fuels respond more slowly than 10-hour fuels to changing weather conditions and are better indicators for extended dry or wet periods. Low 100-hr dead fuel moisture during the growing season is often associated with increased summer wildfire activity. This map is updated every 15 minutes.
