5:30pm 12/21 UPDATE: Snow’s still falling, and by our estimations a grand total of 7-1/2 inches are on the ground now near our home office. That means that an additional 2-1/2 to 3 inches fell since yesterday afternoon, including a hard layer of ice that’s now under about 1-2 inches of snow.

And get this – some are predicting an additional 5-8 inches overnight!

Also, due to this event, Alaska Airlines has canceled all Alaska and Horizon airlines flights into and out of both Seattle and Portland. More info at the Port of Seattle’s airport website here.

Here are some selected weather warning snippets, as well as the latest Winter Storm Warning:

TONIGHT: Snow this evening will give way to lingering snow showers late. Low 28F. Winds E at 5 to 10 mph. Chance of snow 70%. Snow accumulating 2 to 4 inches.

MONDAY: Intermittent snow showers, especially early. Temps nearly steady in the low to mid 30s. Winds NNE at 5 to 10 mph. Chance of snow 40%. Snow accumulations less than one inch.

… Winter Storm Warning in effect until 4 am PST Monday…

The National Weather Service in Seattle has issued a Winter Storm Warning… which is in effect until 4 am PST Monday. The Winter Weather Advisory is no longer in effect.

An additional 3 to 6 inches of snow is expected through tonight in the Puget Sound lowlands and the lower Chehalis valley. A few isolated locations could receive as much as 8 inches. Snowfall amounts will be variable from location to location.

Precautionary/preparedness actions…

A Winter Storm Warning for heavy snow means significant snowfall is occurring or imminent. Snowfall intensities will be heavy enough to reduce visibilities to near zero at times.

Here’s an earlier update from the City of Burien:

No major power outages overnight in Burien
City staff continue to monitor weather conditions. Please check back for weather related closures and information. The weather forecast still calls for more snow, ice and cold temperatures. Go to www.weather.gov/seattle for updated forecasts and weather warnings.

Road crews have plowed and sanded most of the main arterials and are working on the secondaries.  More details about priority routes can be found on our Snow & Ice Routes Map [PDF].

Metro Bus Service:
Once again due to the weather and dangerous driving conditions, King County Metro Transit will be operating approximately half of its normal bus service for Sunday, Dec. 21 and will run three Seahawks shuttles.Information about bus status is available on Metro’s Ice & Snow page, which is updated frequently. You can also call the Metro Customer Information Office at (206) 553-3000, but call volumes are high and there may be a wait to talk to a CIO representative.
Please drive with extreme caution and only if necessary.


Just when you thought Ol’ Man Winter was done introducing his bad self to Brrrien comes this news from the National Weather Service – 2-4 more inches of snow are due to hit the area today:

The Winter Weather Advisory is now in effect until 4 am PST Monday.

After a brief break in precipitation through midday…moderate to occasionally heavy snow showers will move across western Washington with an incoming frontal system. New snowfall accumulations of 2 to 4 inches are likely in the interior lowlands between this afternoon and midnight tonight while heavier 6 to 9 inch accumulations are likely in the mountains. In the mountains east winds gusting to 30 mph will produce some drifting and blowing of the snow.

Snow shower activity will taper off from the north around midnight tonight.

A Winter Weather Advisory means that periods of snow or freezing rain will cause travel difficulties. Be prepared for slippery roads and use caution while driving.
