How to interpret FFMC
Higher FFMC values generally mean finer surface fuels are drier and more receptive to sustained ignition. FFMC also contributes to the Initial Spread Index together with wind.
Fire weather is context, not a local prediction
FFMC is broad fire-weather guidance. It does not predict that an ignition will occur, identify the cause of a wildfire, or measure site-specific fuels on a property.
How FFMC fits into CFFDRS
Canada's Fire Weather Index System connects weather observations to fuel-moisture codes and fire-behaviour indices. FireRadar keeps each component separate so users can see what is actually being measured or derived instead of receiving an opaque combined risk score.
Use official operational guidance for decisions
CWFIS products are broad national fire-weather guidance. Provincial, territorial, Indigenous, municipal and Parks Canada authorities remain responsible for operational fire danger, restrictions, wildfire response and emergency decisions.
Official methodology and source
FireRadar renders the official Natural Resources Canada CWFIS layer directly and preserves the upstream symbology. It does not interpolate a value when the source is unavailable or transform this component into a FireRadar property-risk score.
