Fire Weather Normals

Fine Fuel Moisture Code

The Fine Fuel Moisture Code is a component of the Canadian Forest Fire Weather Index (FWI) System. It is a numeric rating of the moisture content of litter and other cured fine fuels. This code is an indicator of the relative ease of ignition and the flammability of fine fuel.

More information about the Canadian Forest Fire Weather Index (FWI) System is available in the Background Information.

Fire Weather Normals represent the average value of a fire weather code or index over the 30-year period from 1981 to 2010.
