SKAGIT COUNTY — The sun set Thursday over the soggy and worried people of Western Washington while the fast-running Skagit River, full of sediment and debris, swelled.

On Friday at 7:01 p.m. a flood warning was released by the National Weather Service in effect until further notice for Clackamas and Marion counties.

A flood emergency is underway in western Washington as a second surge of heavy rain is causing rivers across the region to rise.Many are expected to crest on T

"The tidal overflow threat continues to decrease as the tide lowers and rainfall rates diminish. Thus the Coastal Flood Advisory will be allowed to expire," states the National Weather Service.

A flood evacuation warning along the Yakima and Naches rivers will stay in place into next week because of more rain in the forecast, officials said Friday.

Authorities are going door-to-door in South Prairie, Washington, in Pierce County, urging residents to leave their homes immediately as water rises there. The Pierce County Sheriff’s Office previously said that at least 25 people have been rescued in the county since Wednesday, including in South Prairie.

The rush is on to protect homes in parts of Renton, where, on Thursday afternoon, the Cedar River surpassed record flood levels.

Flooding is possible from late Saturday night through late Monday night.
