Chandler Burn Index*


CURRENT FIRE RISK IS LOW

Fuels do not ignite readily from small firebrands although a more intense heat source, such as lightning, may start fires in duff or punky wood. Fires in open cured grasslands may burn freely a few hours after rain, but woods fires spread slowly by creeping or smoldering, and burn in irregular fingers. There is little danger of spotting.

*This implementation of the Chandler Burning Index uses the current air temperature and relative humidity to create a numerical index of fire danger.
Then the numerical value is used to determine a fire danger adjective. CBI 0-50 = LOW, 50-75 = MODERATE, 75-90 = HIGH, 90-97.5 = Very HIGH, and >97.5 = EXTREME.
The CBI is linearly sensitive to temperature, but exponentially sensitive to RH, so a small change in RH can make a big change in the CBI number.
