Extreme Forecast Index & Shift of Tails — clipped to CWA

⚠ ESAT endpoint unavailable — The Region Table values are computed from GRIB grid data as a fallback instead of pulled from the operational ESAT endpoint. Values should be close to official ESAT output but may differ slightly due to regional definition differences. CWA-clipped values in the left table are unaffected.
