Probabilities: 24h precipitation
The plot shows probability information derived from the ensemble forecast system (ENS), specifically the Probability of 24-h accumulated precipitation (rain and snow) exceeding 1 mm (colour shading in %).
The probabilities are based on the number of forecast members which meet the criteria (each member is assigned an equal probability of 1/50).
Detailed description of ENS probabilistic products can be found in ECMWF Forecast User Guide.
