Fire Weather Normals

Drought Code

The Drought Code is a component of the Canadian Forest Fire Weather Index (FWI) System. It is a numeric rating of the average moisture content of deep, compact organic layers. This code is a useful indicator of seasonal drought effects on forest fuels and the amount of smoldering in deep duff layers and large logs.

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.
