Chandler Burn Index
Live CBI
|
"Live" Chandler Burn Index is based on the current temperature and humidity and represents the immediate/current conditiions fire intensity. CBI does not use rain history or soil moisture in its calculations. (click image for more info).
LIVE BURN INDEX RISK: 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.
