A simple, but rather complete hydro‐meteorological system for ensemble flash flood forecasting is described. Special focus is put on the use of precipitation forecasts, essentially quantitative and overall probabilistic (PQPFs). A first issue addressed concerns the matching of the time‐step used by the meteorological forecasts providers (12 or 24 h) with the appropriate hydrological time‐step for quick responding catchments (1 h or less). A second issue concerns the forecasts management between two updating cycles of the PQPFs. Finally, ensemble discharge forecasts for a case‐study event observed in Vogüé (South‐eastern France) are illustrated as an application of our flood forecasting system.
