Yikes. This is horrible.

The road that I mentioned I drove to a while ago close to my house that had the temperatures dropping to near 0C that was by the river is where some flooding and evacuation orders are being issued. I'm not in any danger personally but it's happening pretty close to here.

Parts of Skagit County evacuated as ‘catastrophic’ flooding expected to hit region
https://www.seattletimes.com/seattle-ne ... rd-record/

As Western Washington’s watersheds and mountains are getting pummeled by rain Wednesday, river flooding is expected to be “catastrophic” in parts of the Puget Sound.

Record flooding prompted Gov. Bob Ferguson to declare a state of emergency, and Sen. Maria Cantwell, D-Wash., said she’s working to get federal assistance for those impacted.

Authorities have ordered evacuation for parts of Orting in Pierce County, parts of Skagit County, including Mount Vernon, and Ebey Island east of Everett. An estimated 100,000 Washingtonians could face evacuation orders as floodwaters continue to rise, Ferguson’s office said Wednesday afternoon.

In Grays Harbor County, a nearly century old dam in Lake Sylvia State Park is showing signs of stress. Although it hasn’t failed yet, it could get worse if these weather conditions continue.

The Carbon River near Fairfax; Cedar River near Renton; Puyallup River near Orting; Elwha River near Port Angeles; Snohomish River at Snohomish; Stillaguamish River at Arlington; and the Skagit River at Concrete and Mount Vernon were all expected to either swell above their record height or come within inches of the record.

The Skagit was slated to reach major flood stage by Wednesday afternoon, rising aggressively until a peak around 4 a.m. Thursday in the Concrete area.

Hard to be excited about cold and snow while the Valley deals with more potential flooding.
