TAMIR 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
TAMIR Impact ForecastsAnimated 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.
