|Abstract:||In this paper the properties of a hydro-meteorological forecasting system for forecasting river flows have been analysed using a fixed event forecast index (FEFI). The focus on fixed event forecasts provides a forecaster's approach to system behaviour and adds an important perspective to the suite of forecast verification tools commonly used in this field. A high FEFI indicates a more inconsistent forecast. It can be demonstrated that the annual maxima of FEFI decreases over the last 10 years; ensemble forecast, control and high resolution forecast have a different behaviour. The FEFI is influenced by the threshold, catchment size and catchment location. It indicates that one should use seasonality based decision rules to issue flood warnings.|
