Abstract. An Early Warning System for flood prediction based on precipitation forecast is presented. The system uses rainfall forecast provided MeteoGalicia in combination with a hydrologic (HEC-HMS) and a hydraulic (Iber+) models. The upper reach of the Miño River and the city of Lugo (NW Spain) are used as a study area. Starting from rainfall forecast, HEC-HMS calculates the streamflow and Iber+ is automatically executed when a certain threshold is exceeded for some previously defined risk areas. The analysis based on historical extreme events shows that the system can provide accurate results in less than one hour for a forecast horizon of 3 days and report an alert situation to decision-makers.

Short summary
An Early Warning System (EWS) for flood prediction was developed in the upper reach of the Miño River and the city of Lugo (NW Spain). This EWS can provide accurate results in less than one hour, for a forecast horizon of 3 days, and report an alert situation to decision-makers in order to mitigate the consequences of floods. In addition, this EWS can be easily adapted for any area of the world since the required input data and software are freely available.
