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.

Image shows current CBI Fire Danger, Current Temp, Humidity, CBI rating, CBI spread component and intensity component.


*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.
