All affected customers restored, utility says
Seattle City Light’s latest statement says crews were able to restore all customers affected by this outage. Its earlier 9:51 a.m. PDT update attributed the interruption to equipment failure and said crews were on site working to restore electricity. The utility does not identify the failed component or underlying trigger. Recovery is the operator’s report for this event, rather than an independent check of every connection.
The initial 6:11 a.m. PDT notice named Shoreline and North Seattle and gave an approximate figure of 6,000 affected utility customers. That is a customer count, not a count of people, and it describes the initial reported impact. No complete street list or geographic boundary is supplied. It cannot establish that every property in either named area lost electricity or that the interruption extended across Seattle.

Earlier uncertainty and traffic advice
The first utility notice said the cause was under investigation and a restoration estimate had yet to be determined. The equipment-failure announcement replaced that earlier cause uncertainty, and the newer statement now reports recovery. Exact onset remains unknown: the 6:11 a.m. PDT timestamp records publication, rather than a confirmed start. The 10:20 a.m. PDT restoration post likewise does not establish the final switching time, so no precise interruption duration can be calculated.
At 7:16 a.m. PDT, transportation-authority account SDOTtraffic posted an advisory about the outage in Shoreline and North Seattle. It asked drivers to treat dark signals as an all-way stop and use caution. This remains an attributed traffic advisory, without an inventory of failed intersections or confirmation of which signals are currently dark. It does not establish citywide traffic disruption or provide a separate customer count.
