Chandler Burn Index

Live CBI

"Live" Chandler Burn Index is based on the current temperature and humidity and represents the immediate fire threat. (click image for more info).

LIVE BURN INDEX RISK: 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.
