Therefore, there will be a Moderate Risk of severe thunderstormsand excessive rainfall over the area.Meanwhile, onshore flow and a steady stream of upper-level energy over thePacific Northwest will trigger rain and snow melt over parts of thePacific Northwest into the Northern Intermountain Region from earlySaturday into Monday. On Sunday the rainfall will increase, therefore, theWPC has issued a Slight Risk (level 2/4) of excessive rainfall over partsof the Pacific Northwest from Sunday through Monday morning.
