| TAMIR Impact Catchment Summaries | The 90th percentile over each sub-catchment of the maximum gridded flash flood impact level forecasted | Short-range | TAMIR 24-h accumulations | Precipitation accumulations are forecasted for the upcoming 5 days. The product is displayed as a summary for four lead time aggregation windows : (0-6h), ( 7-24h), ( 25-48h), and ( 49-120h). The precipitation accumulations have been obtained by seamless blending of radar-based ensemble nowcasts and precipitation forecasts of an NWP EPS (for the first 6 hours). For further information, check the documentation here. | Map | 5 days | . 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. | Map | 0-120h |
| TAMIR Impact Forecasts | Animated hourly forecasts of flash flood impact levels over then 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.

| TAMIR Total Precipitation 80th Percentile | Animated precipitation accumulations forecasted up to 120 hours ahead | Short-range | TAMIR - impact forecasts | 1-h precipitation accumulations forecasted for the upcoming 6 hours obtained by seamless blending of radar-based ensemble nowcasts and precipitation forecasts of an NWP EPSfrom the ECMWF ensemble. The displayed accumulations correspond to the forecasts obtained with the control member80th percentile of the ensemble forecast. For the first 6 hours of the forecast, the timestep is 1 hour, thereafter the timestep is 6 hours, and is specified in a box above the animation time slider.

TAMIR | - Total precipitation 80th percentilelegend is blank on stage | Past 24-h Precipitation | This layer shows the 24 hour accumulated precipitation as estimated from gauge-adjusted OPERA radar composites from the pan-European OPERA radar rainfall network blended with short range precipitation forecasted by the ECMWF ensemble. This layer is generated at 00 and 12 UTC every day, the values refer to the total accumulated precipitation in the preceding 24 hours.
