On the right, the probability of exceeding two thresholds (MHQ and MQ) versus lead-time is shown.

Estimation of the hazard level is based on the rainfall aggregated on the drainage network (defined with a resolution of 1km), which is used as the variable that characterizes the flash flood potential. The thresholds used for the different hazard levels depend on the regional climatic characteristics and the size of the catchment defined upstream of each point of the drainage network. The flash flood hazard level is updated every 15 mins in line with the rainfall accumulation (1h) layer. |

The thresholds for high and low probability are with respect to the 90th and 10th percentiles of the simulated discharge from a 29-year model climatology run (1991 - 2019).
