GloFAS · approximately 5 km
Hydrological trend, not an alert
Current and forecast modelled discharge is compared with a historical monthly reference in the same grid cell. A rise suggests increasing hydrological activity, not flooding at a specific settlement.
Not an official warning: for immediate risk follow 112, Civil Protection, official forecasts and local authorities. Never approach a river channel or flooded crossing.

How to interpret this service
📈 Relative change
Comparison uses the model mean for the same month and grid cell. Trend is more useful than the absolute number.
🧩 5 km grid
The API selects the largest river in an approximately 5 km area and may match another branch near small rivers.
🏞 Regulation
Reservoirs, diversions and gates may not be correctly represented by the global model.
🌧 Local flooding
Flash or urban flooding may occur without appearing early in the discharge of a large river.
🟠 Colour levels
These are e‑meteo relative categories, not official GloFAS or Greek authority thresholds.
🚨 Actual event
Move away from rising water and never cross a flooded road or bridge.
Data sources and terms of use

Historical reference
Modelled 1991–2020 monthly mean in the same representative grid cell where available.
Limitations
No alert, evacuation instruction or official threshold is issued. Official authorities always take priority.
