WASHINGTON — We have been seeing a much-needed break in the wet, windy weather today but that will come to a very quick end into this evening as the atmospheric river moves back north from its quick visit to Oregon.
Western Washington will once again see very wet and breezy conditions tonight through Thursday morning.
While overall rainfall might not be as heavy in spots as in Round 1 on Monday, this will last a bit longer, soils are completely saturated, and river systems cannot hold more water without flooding.

Aside from the Skagit at Mount Vernon, all rivers will have fallen out of flood stage or at least out of the serious danger zone by late Friday.
The Skagit will take a little longer to come down but we’re out of this problem period by Friday night ahead of a drier weekend.
However more rainy, windy storm systems are possible next week so we might not be done with flooding and other concerns even after this week.
