5-day river-discharge FORECAST near an Australian location — Copernicus CEMS Global Flood
Awareness System (GloFAS, operational LISFLOOD control run), retrieved daily from the CEMS
Early Warning Data Store and served from cache (the answer is instant — never waits on the
CDS queue). The forward-looking sibling of au_water: au_water = what AU rivers are DOING
(live gauges), flood_forecast = what the global model expects them to do over the next 5
days. Returns the strongest modelled river cell within ~90 km: 24 h-mean discharge (m3/s)
per day for ~5 days, the peak value + day, and a rising/falling/steady trend; values are the
MAX within ~25 km (0.25-deg max-pooled) cells. `location` = an AU preset ("brisbane"
default, "sydney", "melbourne", "adelaide", "hobart", "darwin", "canberra", "perth") or a
"lat,lon" string; explicit `lat`/`lon` override. Raw model guidance ONLY — no flood
thresholds or severity classifications are added, and this is NOT a flood warning; official
AU flood warnings/watches are issued by the Bureau of Meteorology at
bom.gov.au/australia/warnings. Attribution: contains modified Copernicus Emergency
Management Service information.
Every value is returned in an Ed25519-signed, provenance-stamped envelope (source and observation time) you can verify offline against /.well-known/keys, no account required.
