10:24 AM: Thanks to Susan for the tip – power is out for what Seattle City Light says is 108 customers (homes/businesses) in The Arroyos and vicinity. The cause isn’t yet known, but the utility hopes to have power back by mid-afternoon, as of the latest guesstimate.
P.S. This is the same footprint and customer count as the outage this past May that lasted more than 24 hours.
11:21 AM: Scott Thomsen of City Light tells WSB that the outage has been traced to “equipment failure” and they’re now hoping to have the power back by 4:30 pm.
7:36 PM: As pointed out in comments, it’s not fixed yet and the restoration guesstimate is now past midnight. SCL says an underground cable is what failed.
11:05 PM: Still out, says the City Light outage-tracker map, now pushing the guesstimate to 4 am-ish.
6:35 AM: JL says in comments that the power returned at 5 am – that would have been after more than 20 hours.
