Multi-parameter EFI (24-h up to valid time)
Base Time: Fri 15 Aug 2025 00 UTC T+24 Valid time: Sat 16 Aug 2025 00 UTC (T+24)
This chart shows where the ENS system expects anomalous weather to occur using symbols - pink for wind and green for rain, and shading for the temperature.
The basis for the symbols is the Extreme forecast index (EFI), which compares the ENS distributions from a particular ENS run with the model climate.
ENS mean of Mean sea level pressure contours are overlaid to aid the interpretation.
Detailed description of EFI products can be found in ECMWF Forecast User Guide.
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.

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