Fire Weather Maps
The Duff Moisture Code is a component of the Canadian Forest Fire Weather Index (FWI) System. It is a numeric rating of the average moisture content of loosely compacted organic layers of moderate depth. This code gives an indication of fuel consumption in moderate duff layers and medium-size woody material.
More information about the Canadian Forest Fire Weather Index (FWI) System is available in the Background Information.
