Winter weather advisory in Cascades and parts of Western Washington

Winter weather advisory

A winter weather advisory is in effect from until noon Monday for locations above 2,500 feet around the Cascades of Whatcom, Skagit, Snohomish, King, Pierce and Lewis counties.

IMPACTS: Freezing rain is possible above 2,500' where some pass locations could see 1/4" of ice on the roads. Wet snow is possible above 3,000' with most locations not expected to see snow accumulation unless they are over 4,000'. Around 4,000 feet or higher we could see up to 3 inches, so not a ton. The bigger impact will be potential for VERY SLICK ROADS over the passes tonight and early tomorrow morning!! 

While most locations do have a very small chance of rain - most models really only indicate the Olympic Peninsula and possibly Western Whatcom County with any chance of accumulating rain.

We'll see a stronger front push through tonight and tomorrow that will bring a return of the rain and create some wet roads for Monday morning commuters.


We could see some decent rain around the Olympics which is why the NWS Seattle has issued a real flood watch for Mason County because of heavy rain on the South side of the Olympics. 3-7' of rain currently forecast for the Skokomish River Basin from 4:00 a.m. Monday - 4:00 a.m. Tuesday. We could see some moderate flooding on the Skokomish River Monday night.

Looking ahead we'll keep our rainy pattern around through at least the mid part of the work week with showers still expected by late week.
