Chandler Burn Index

Chandler Burn Index is based on the current temperature and humidity (click image for more info).

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.
