Flood Summary Products Overview

Probability of ECMWF-ENS forecasts exceeding the EFAS 5-year return period threshold. Forecasting range 0-48 hours. 

Probability of ECMWF-ENS forecasts exceeding the EFAS 5-year return period threshold. Forecasting range 2 -10 days.

Map

Estimated flood extent at 100m resolution based on forecasted flood magnitude. Protection levels considered in estimation are available under ‘Background layers.’ Note: If EFAS doesn’t forecast significant flood impact the layer will be empty. Regions shaded grey are where flood return periods fall below the estimated flood protection levels, therefore flood impacts are not expected. (More information).

Potential impact of floods on population, land use (agriculture, urban) and infrastructures (major roads). Impacts are based rapid floos mapping and aggregated over NUTS regions. The level of flood risk is derived from the combination of expected impacts and likelihood. Note: If EFAS doesn't forecast significant flood impact the layer will be empty. (More information).

Reporting Points where forecast outputs are available. Red (yellow) squares highlight stations where the flow is forecasted to exceed the EFAS 5-year (2year) return period. Dark outlines indicate a threshold exceedance within the next two days. The labels show the ECMWF-ENS (left) and COSMO-LEPS (right) forecast probabilities and the forecast probability tendency over the last 3 forecasts (arrows). Grey (blue) squares are stations where (real-time post-processed) forecast hydrographs are available. For these points, red (yellow) outlines signify that the flow is forecasted to exceed the EFAS 5-year (2-year) return period, but they do not meet the criteria to be flood reporting points. (More information).

Reporting points where maximum discharge is expected today (within the next 1-2 days; 3-5 days; >5 days). Roman numbers denote when exactly maximum discharge is expected. Colour denotes the highest alert level expected by a certain forecast.
