Precipitation: Weekly mean anomalies
Base Time: Thu 12 Jun 2025 00 UTC T+264 Valid time: Mon 16 Jun 2025 00 UTC - Mon 23 Jun 2025 00 UTC
Weekly mean anomalies have been calculated relative to a 20-year model climatology. The areas where the ensemble forecast is not significantly different from the climatology, according to a WMW-test, are blanked.
Note that shaded areas are at 10%, contours are at 1% significant level.
