*WIND SPEEDS REPORTED IN MPH
Washington was very windy as well, but I couldn’t find any statistics posted on the NWS Seattle page. Nevertheless, Bellingham had a gust to 70 miles per hour Tuesday morning, which is pretty incredible. Sea-Tac’s all time highest gust was 69 miles per hour back in the Hanukkah Eve Storm of December 14-15, 2006.
Now, let’s talk about the current weather situation.
The National Weather Service for Seattle has issued a ton of warnings for our incoming storm! Winter storm warnings for the Cascades, high wind warnings for the coast and north interior, and storm warnings for the offshore waterways into the Strait of Juan de Fuca, around the San Juan Islands, and heading up into the Strait of Georgia. Take a look at the satellite image below, and you’ll see the storm that is currently causing all of this weather mayhem.
01:30 pm PST Thu 24 Nov 2011 – West Coast 8km resolution water vapor satellite
The storm, a mature 972 millibar low heading up into Northern Vancouver island, is much faster than the previous storm, so the rain should pass through in the next couple hours, and the winds will calm down rapidly everywhere by 10 P.M., with many locations improving sooner than that. For current Thanksgiving travelers, the biggest problem will be snow over the Cascades, which will not let up until Friday morning. The latest model from the UW indicates anywhere from 10-18 inches above 2,500 feet or so. 
Valid 04:00 am PST Fri, 25 Nov 2011 – 24hr Fcst – UW 12z 4/3km 24-hour snowfall
Snow has started falling in the Cascades, even at Snoqualmie Pass.
Snoqualmie Pass always seems to get hammered on Thanksgiving… I can remember writing blog posts in the past about this. If you must drive over the pass, drive slow, bring chains, and be prepared for delays.
Have a nice Thanksgiving!
