December 8 started off with a literal bang across the Puget Sound area as a massive squall line moved through the region.
Heavy rain, lightning, and winds gusting at times over 50 mph blasted through during the peak of the Wednesday morning commute.
Power was knocked out to just over 4,000 people in the North Seattle are after a tree blew into a feeder line. Most had their power back except for a few scattered lightning-caused outages around the city. Kitsap County was also reporting outages in their northern and central county. A viewer says the power was also out in Maltby for a while. Grays Harbor also had a few outages as a squall generated a gust of 60 mph at Hoquiam Airport.
Meanwhile, standing water caused several issues on local roadways, including parts of I-5. The Seattle Department of Transportation reported that water was over the roadway at Mercer and Aurora, snarling traffic there for a while. .
Everett reported a gust of 58 mph during the peak of the squall, while a spotter in Bellingham had a gust to 54 mph.
Most airports between Seattle and Everett reported about 1/4" of rain in an hour, but I suspect there will be greater totals out there from individual spotters.
The squall moved off to the northeast and by 10 a.m. the sun was shining and you'd have never guessed what the region went through just an hour prior.
