Nearly 4 inches of rain had fallen at Snoqualmie Pass through late Tuesday evening which not only put pressure on central Cascade rivers but also contributed to an extreme avalanche danger.
Flood Warnings remained in effect for the Pilchuck, Stillaguamish, Tolt, Snoqualmie and Puyallup Rivers with Flood Watches in effect for all other rivers. Moderate flooding was predicted on the Snoqualmie River while minor flooding was expected elsewhere.
In addition to the flood warnings, the National Weather Service warned of a moderate risk of landslides in parts of the region, including the greater Everett/Snohomish County area, the Cascade foothills and western Skagit County where the heaviest of the rain has fallen in the lowlands. As much as 2-6 inches of rain have fallen so far with another 1-3 inches expected overnight Tuesday.
Meanwhile, the greater Seattle, Tacoma and Kitsap Peninsula areas have been largely shielded from the rain due to the Olympic Rain Shadow. Seattle had only received 0.02 inches of rain Tuesday, while Bremerton reported nary a drop.
The Pineapple Express-type storm that was drenching the area Tuesday will slowly slide south Tuesday night and into Wednesday, ending the rain from north to south as it does so.
Rain will taper off through the morning Wednesday and by midday, we're left with just some scattered showers. Snow levels will drop to about 2,500 feet by Wednesday morning once the warm storm moves away and cooler air moves in from the north. And that means we go back to snow warnings in the mountains.
Speaking of which: A Winter Weather Advisory is in effect for the Cascades -- including Snoqualmie Pass and Stevens Pass, for up to 6-12 inches of snow there Wednesday.
The changeover to snow will keep from adding more water into the rivers and most rivers should crest by mid to late Wednesday, depending on your distance downstream.
But all this snow-to-rain-to-snow again is not going to help the avalanche situation up there though
We taper everything off Thursday which is looking mainly dry and perhaps even partly sunny -- a quick day to catch your breath. Our next storm arrives on Friday, although this one looks much more routine of rainy lowlands, snowy mountains, and breezy winds to 25-35 mph and highs in the upper 40s.
