The Cedar River in Renton and near Landsburg is still causing problems. The river is under a flood warning until Tuesday night, and the waters are still so high some pathways are still under water.

The Green River also remains under a flood warning in Auburn.

KIRO 7 Meteorologist Nick Allard expects both rivers to drop below flood stage by Tuesday morning.

Through the rivers are receding after the rain let up, there are still a lot of roads closed across King County in places such as Auburn, Maple Valley, Carnation, Redmond, Sammamish, and others.

Mudslides and flooding are blocking all roads leading into Mount Rainier National Park.

That includes State Route 706, also known as the “road to Paradise.” Drivers are being asked to stay away from the highway for their safety because of an unstable hillside above the highway.

For those who live in the area, the National Park Service will have an escorted convoy to get homeowners to and from their homes Monday. Convoys are tentatively scheduled for Wednesday and Friday.

“National Park Service has told us the access road will last longer if the convoys are every other day. This will allow them to maintain emergency access and the keep convoys going while WSDOT works on SR 706,” the Pierce County Department of Emergency Management said.

State Route 410 was blocked by four slides but a stretch of the road has reopened to local traffic to milepost 48, WSDOT officials said Sunday.

Luckily, the weather is trending to be on the drier side this week after a very wet month-and-a-half. Though there will still be some rain, it won’t come close to what led up to the flooding. Read Nick’s forecast here.

People who call the Nisqually Delta area home are returning to find a huge cleanup ahead of them.

The parking lot of the Riverside Manor apartments remained flooded this weekend. Neighbors were pumping water back into the Nisqually River.

Thurston County officials are advising flooded residents to start removing whatever is damaged as soon as they return home.

Emergency officials are also asking some in the Nisqually Delta area to boil their water before using until further notice. Those who get their water and their bill from the city of Lacey are not affected.

“The water the City of Lacey supplied to you was from a well located in an area unaffected by the flood,” the city said Monday.

Sunday night update:

Updates from KIRO 7 Meteorologist Claire Anderson:

Mostly clear and dry tonight with overnight dropping into the mid to upper 30s.

Several rivers still at moderate flood stage-- including Cedar River. Minor flood stage reported on the Green River. Several flood warnings still around Western Washington, but waters will slowly recede into the workweek.

We’re mainly sunny and dry Monday after areas of patchy freezing fog with highs in the 40s --

We could get a few sprinkles with a weak weather system Tuesday into Wednesday, but rain looks minimal if anything does fall.

Rain chances return Thursday and Friday of next week, but this is not connected with another atmospheric river and will not induce flooding.

The King County Flood Warning Center issued a Phase 4 flood alert for the Green River with severe flooding possible following planned releases from a flood-control dam.

Road closures:

Many roads and state highways were closed, prompting fears some residents could get stranded.

In Carnation, Tolt Hill Road was closed by floodwaters as the Snoqualmie River continued to rise. A large National Guard vehicle will be in the city through Saturday to assist people, if necessary.


In Issaquah, streets remain submerged by flood waters, causing hundreds of people who live near Issaquah Creek to evacuate. Though the water is starting to recede, there is still severe flooding.

South Sound:

Hundreds of others in the South Sound remain evacuated from their homes as the rising Nisqually River put homes at risk. The LaGrande Dam, upstream of the Nisqually Valley, had to increase its water flow to handle the heavy rain.

Water levels at the Snohomish River weren’t expected to drop until Saturday evening.
