Overview
- Heavy rain and gusty winds arrived Monday with a first round lasting into early Tuesday, a daytime lull Tuesday, and a stronger second round expected Tuesday night through Wednesday.
- The Northwest River Forecast Center projects major flooding on multiple rivers, including the Cowlitz, Nisqually, Puyallup, Skagit, Skykomish, Snoqualmie, and White.
- The Puyallup River is forecast to crest at major flood stage late Monday night into early Tuesday, while the Tolt River is expected to crest at moderate flood stage in the same window.
- Mountain and coastal totals could exceed 10 inches through Wednesday, with some spots in southwest Washington and northwest Oregon nearing 15 inches, heightening runoff and landslide risk.
