Day 2
Valid 12Z Wed Dec 17 2025 - 12Z Thu Dec 18 2025

The probability of rainfall exceeding flash flood guidance is less
than 5 percent.

QPF from the 16/00Z operational and ensemble guidance continued to
trend down with a correspondingly smaller risk of excessive
rainfall. That...combined with the higher precipitation amounts
being confined to higher elevations in Washington where
precipitation type would mainly be snow...should limit the overall risk
of excessive rainfall to less than 5 percent.
