Chandler Burn Index*


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.

*This implementation of the Chandler Burning Index uses the current air temperature and relative humidity to create a numerical index of fire danger.
Then the numerical value is used to determine a fire danger adjective. CBI 0-50 = LOW, 50-75 = MODERATE, 75-90 = HIGH, 90-97.5 = Very HIGH, and >97.5 = EXTREME.
The CBI is linearly sensitive to temperature, but exponentially sensitive to RH, so a small change in RH can make a big change in the CBI number.
