Multi-parameter EFI (24-h up to valid time)
Base Time: Tue 25 Aug 2026 18 UTC T+30 Valid time: Thu 27 Aug 2026 00 UTC (T+30)
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.
