Multi-parameter EFI (24-h up to valid time)
Base Time: Fri 03 Apr 2026 12 UTC T+36 Valid time: Sun 05 Apr 2026 00 UTC (T+36)
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.
Forecasts, analyses, climate reanalyses, re-forecasts 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 licence agreement types.
