. Two different systems provide long-range forecasts at ECMWF. On thesub-seasonal timescale, ECMWF issues an extended-range ensemble predictionsystem (ENS-ER) which runs a 46-day forecast integration issued twice weekly.On longer timescales, the current seasonal forecasting system (SYS4) producesa 7-month outlook starting from the first of each month. SYS4 uses an oldermodel version and has lower spatial and temporal resolution than ENS-ER,which is issued with the current operational ensemble forecasting system.Given the substantial differences between the ENS-ER and the SYS4configurations and the difficulties of creating a seamless integration,applications that rely on weather forcing as input such as the European FloodAwareness System (EFAS) often follow the route of the creation of twoseparate systems for different forecast horizons. This study evaluates thebenefit of a seamless integration of the two systems for hydrologicalapplications and shows that the seamless system outperforms SYS4 in terms ofskill for the first 4 weeks, but both forecasts are biased. Thebenefit of the new seamless system when compared to the seasonal forecast canbe attributed to (1) the use of a more recent model version in thesub-seasonal range (first 46 days) and (2) the much more frequent updates ofthe meteorological forecast.
