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.

Supercomputing and cloud resources available for weather and climate research
Forecast charts and data
We provide current forecasts, climate reanalyses and specific datasets. These are available via the web, point-to-point dissemination, data servers and broadcasting.
New #weather & #climate #OpenData mailing list!
Together with @EUMETSAT, @Meteorologene & @dwd_klima, we aim to share new & updated open datasets, and relevant resources, conferences & articles.
For more about ECMWF open data & how to subscribe to the mailing list, click here.
Forecasts, analyses, climate re-analyses, reforecasts and multi-model data are available from our archive (MARS) or via dedicated data servers or via point-to-point dissemination.
Researchers, WMO members, commercial users and satellite data providers can gain access to ECMWF forecast products under one of our various license agreement types.
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.
