Radar-based River Flash Flood Impact Catchment Summaries

The 90th percentile over each sub-catchment of the maximum gridded flash flood impact level forecasted for four lead time aggregation windows (0-6h, 7-24h, 25-48h, 49-120h). Flash flood impact is based on flash flood hazard forecasts and exposure data. When a sub-catchment is clicked, a pop-up window displays further information about the potential exposure and the location of the forecasted event within the impact matrix. For further information, check the product page.Map0-120h

Radar-based River Flash Flood Impact Forecasts

Animated hourly forecasts of flash flood impact levels over the river network for the next 6 hours, then 6-hourly forecasts until a leadtime of 120 hours. During each timestep each grid cell is shaded according to the combination of the flash flood hazard forecast at that timestep and static exposure data on an impact matrix. For further information check the product page.
