Probabilities: 24hr total precipitation

Base Time: Sat 19 Jun 2021 12 UTC T+24 Valid time: Sun 20 Jun 2021 12 UTC

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.

Saildrone to help ECMWF understand the Gulf Stream

ECMWF is to ingest data from Saildrone uncrewed surface vehicles (USVs) later this year to improve our understanding of the behaviour of the Gulf Stream and its influence on weather. Up to six solar-powered USVs will cover a part of the Gulf Stream that is crucial for forecasts.

Datasets

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.

Accessing forecasts

Researchers, WMO members, commercial users and satellite data providers can gain access to ECMWF forecast products under one of our various license agreement types.

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.
