5:43 PM: Thanks to Helen for the tip: There’s a small power outage around Fairmount Ravine – 21 homes, according to the Seattle City Light outage tracker – with a downed tree/wires reported to be to blame. (Bev says, via Facebook, Fairmount is blocked between Harbor and Forest.)

9:51 PM UPDATE: City Light has updated the marker to 13 homes, with power expected back for them around 1 am. We also have added a photo shared by Helen, showing the problem.
