The Canadian Wildland Fire Information System monitors fire danger conditions and fire occurrence across Canada. Daily weather conditions are collected from across Canada and used to produce fire weather and fire behavior maps.

It combines the Initial Spread Index (a numerical rating of the expected rate of fire spread) and the Buildup Index (a numerical rating of the total amount of fuel available for combustion). It is suitable as a general index of fire danger throughout the forested areas of Canada.
Fire Weather Maps. Fire Danger is a relative index of how easy it is to ignite vegetation, how difficult a fire may be to control, and how much damage a fire may do. Note: These general fire descriptions apply to most coniferous forests.
Fire Behavior Maps. Head Fire Intensity (HFI) is the predicted intensity, or energy output, of the fire at the front or head of the fire. It has become one of the standard gauges by which fire managers estimate the difficulty of controlling a fire and select appropriate suppression methods.
The Fire Weather Index is a component of the Canadian Forest Fire Weather Index (FWI) System. It is a numeric rating of fire intensity. It is based on the ISI and the BUI, and is used as a general index of fire danger throughout the forested areas of Canada.
The Canadian National Fire Database (CNFDB) is a collection of forest fire data from various sources; these data include fire locations (point data) and fire perimeters (polygon data) as provided by Canadian fire management agencies (provinces, territories, and Parks Canada).
Daily weather observations are required for the Canadian Forest Fire Weather Index (FWI) System calculations. More information about weather processing and the FWI system is available in the Background Information. Forecasted weather data provided by Environment Canada.
