How to interpret DSR
Higher DSR values indicate conditions associated with greater expected control difficulty in the system's standard context. DSR is useful for comparing overall daily fire-weather severity across time and space.
Fire weather is context, not a local prediction
DSR is not a staffing recommendation, incident-specific suppression forecast, evacuation trigger or public-safety score. Operational agencies remain authoritative for response decisions.
How DSR 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.
