Wild Fire Risk This Chandler Burn Index is recorded at the peak temperature of the day. CBI Index will increase during the day as temperatures increase. This can be looked at as the fire risk for the hottest (most dangerous) time of the day whereas the chart below this indicates the current "live" CBI reading..
FWI - Details and History

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 HIGH

All fine dead fuels ignite readily and fires start easily from most causes. Unattended brush and campfires are likely to escape. Fires spread rapidly and short-distance spotting is common. High-intensity burning may develop on slopes or in concentrations of fine fuels. Fires may become serious and their control difficult unless they are attacked successfully while small.
