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: EXTREME ... Fires start quickly, spread furiously, and burn intensely. All fires are potentially serious. Development into high intensity burning will usually be faster and occur from smaller fires than in the very high fire danger class. Direct attack is rarely possible and may be dangerous except immediately after ignition. Fires that develop headway in heavy slash or in conifer stands may be unmanageable while the extreme burning condition lasts. Under these conditions the only effective and safe control action is on the flanks until the weather changes or the fuel supply lessens.
