  • •Scale — EFFIS Fire Weather Index classes: low, moderate, high, very high, extreme. FWI measures how readily fire would spread today given recent weather — not whether a fire will start.
  • •Forecast — 15-day outlook from ECMWF IFS HRES (deterministic, 0.1°) and IFS ENS (51-member ensemble, 0.25°).
  • •FWI inputs — Daily aggregates as a noon-LST proxy: afternoon max temperature, min relative humidity, max wind, and 24h precipitation. Values track the operational FWI pattern but may run slightly hot versus the noon-LST reference. To see actual noon-LST FWI values, sign in to Wildflyer.
  • •Updates — Refreshed daily.
