Chandler Fire Weather Index / Sartell Area
Chandler Burning Index Alert Levels
The Chandler Burning Index (CBI) uses the air temperature, relative humidity, 10 minute average wind and the previous 24 hours of rainfall to calculate a numerical index of fire danger. That number is then equated to the Fire Danger severity of either extreme, very high, high, moderate, or low. It's based solely on weather conditions, with no adjustment for fuel moisture.
