Probabilities: 24hr total precipitation

Base Time: Sat 28 May 2022 12 UTC T+24 Valid time: Sun 29 May 2022 12 UTC (T+24)

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.

Serving meteorology

International collaboration is fundamental to the work of ECMWF, working with the EU and the meteorological community at large, including the World Meteorological Organization, space agencies, and scientists around the world.

Workshops and education

Education is a key element of our work at ECMWF, enabling our partners to get the most from ECMWF's services and develop an advanced understanding of forecasting.

ECMWF lecture theatre

ECMWF workshops are open to the worldwide meteorological community, though some training is restricted to member states.
