8:12 PM: Thanks for the tip. Small power outage in Alki – five customers lost power about an hour ago, per the Seattle City Light map – but notable because of the weather. Our tipster reports hearing what may have been a fuse blowing; the map does not yet note a cause.
9:27 PM: “Equipment failure” is listed as the cause.
12:25 AM: As noted in comments, there was also a 4-customer outage around 50th/Hudson. That has already ended but the Alki outage is in its sixth hour.
