Friday’s historic storm (which actually started Thursday afternoon) that included an atmospheric river of moisture dropped nearly 7 inches of rain in the Snoqualmie Valley in just two days. 3.25″ fell Friday at SeaTac Airport, making it the 5th rainiest day on record for the region.
The Snoqualmie River [near Snoqualmie] crested overnight at around 22,000 cfs – a phase 3 moderate flood event for the upper Valley. In Carnation, the river is expected to crest today at around 58 feet.
Multiple roads were closed as of Saturday morning, December 21st. You can see a full list on the King County Roads page HERE. Rain is expected to continue, but ease up in intensity, throughout Saturday.

Commuters felt the storms wrath on Friday when SR 203 was closed for hours between Carnation and Duvall after a small landslide closed both directions at milepost 8 – near Stillwater Store.
Washington State Trooper Rick said the slide – north of Carnation between Stillwater Store and the 124th roundabout – brought down trees, which then pulled down power lines.
The slide, which occurred around 9AM, also caused a two-car, non-injury collision. Police put a detour in place. There currently is no ETA for reopening SR 203 in the area.
WSP also closed SR 202 near 292nd Ave SE (Duthie Hill Road) west of Fall City due to flooding. Drivers were asked not to attempt driving around police vehicles at each end of the closure.
There was also fast-moving water over SR 202 near Ames Lake Road. Police kept the roadway open, but encouraged drivers to proceed slowly.
In Fall City, SE Fish Hatchery Road between 361st Avenue SE & 372nd Avenue SE was closed due to water over the roadway. Near Carnation, NE 80th St between West Snoqualmie Valley Rd and Ames Lake/Carnation Rd also closed.
Another mudslide on East Lake Sammamish Pkwy at NE 30th in Issaquah/Sammamish also closed lanes early in the morning, but was cleared around 9:40AM.
The steady, heavy rain is expected ease up throughout Saturday, December 21, 2019.
Comments
The water is getting deeper over SR 202 near Ames Lake Road!!
Thanks for letting us know! King county roads STILL doesn’t have the road listed as closed.
Would be nice if King County would keep us up to date.
