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.

The Fire Weather Index (FWI) is based on weather readings taken at noon standard time and rates fire danger at the mid afternoon peak from 2:00 4:00 pm. To interpret the system, the three fuel moisture codes and the three behaviour indices need to be understood. Each code and index is a numerical rating related to likely fire behaviour. The scales start at zero, and except for the Fine Fuel Moisture Code which has a maximum of 99, all are open-ended. Low ratings indicate high moisture content, and ratings rise as moisture content decreases. Ratings rise as fire weather becomes more severe.

Weather readings required are:

  • Air temperature (in the shade)
  • Relative Humidity (in the shade)
  • Wind speed (at 10 metres above ground level for an average over 10 minutes)
  • Rainfall (For the previous 24 hours)
  • The Fire Weather Index has six components:

    Three Fuel Moisture Codes:

  • 1. Fine Fuel Moisture Code
  • 2. Duff Moisture Code
  • 3. Drought Code
  • Three Fire Behaviour Indices:

  • 1. Initial Spread index
  • 2. Build Up Index
  • 3. Fire Weather Index

  • Drought Code

    The DC is a numerical rating of the moisture content of deep, compact, organic layers. It is a useful indicator of seasonal drought and shows the likelihood of fire involving the deep duff layers and large logs. A long period of dry weather (the system uses 52 days) is needed to dry out these fuels and affect the Drought Code. A DC rating of 200 is high, and 300 or more is extreme indicating that fire will involve deep sub-surface and heavy fuels. Burning off should not be permitted when the DC rating is above 300.


    Build Up Index

    The Build Up Index (BUI) shows the amount of fuel available for combustion, indicating how the fire will develop after initial spread. It is calculated from the Duff Moisture Code and the Drought Code. The BUI scale starts at zero and is open-ended. A rating above 34 is high, above 77 is extreme.


    Initial Spread Index

    0.0-3.9

    4.0-7.9

    V HIGH

    EXTREME
    19.0+

    The Initial Spread Index (ISI) indicates the rate fire will spread in its early stages. It is calculated from the FFMC rating and the wind factor. The open-ended ISI scale starts at zero and a rating of 10 indicates high rate of spread shortly after ignition. A rating of 19 or more indicates extremely rapid rate of spread.


    Fine Fuel Moisture Code
    LOW
    0.0-80.9

    The Fine Fuel Moisture Code (FFMC) is a numerical rating of the moisture content of surface litter and other cured fine fuels. It shows the relative ease of ignition and flammability of fine fuels. The moisture content of fine fuels is very sensitive to the weather. Even a day of rain, or of fine and windy weather, will significantly affect the FFMC rating. The system uses a time lag of two-thirds of a day to accurately measure the moisture content in fine fuels. The FFMC rating is on a scale of 0 to 99. Any figure above 70 is high, and above 90 is extreme.

    The Grass Fire Danger Code (GFD) is based on predicted generated "fire intensity (kw/m)" in grass type vegetation (dry grass, tussock). This code denotes how difficult it would be to control a fire in this vegetation type should one start.
