9:56 AM: 911 callers from Beach Drive just reported “a loud explosion, and then the power went out” – and indeed, the Seattle City Light outage map shows 262 customers out of power in South Alki, as of 9:48 am. No word yet on the exact cause but the “explosion” generally suggests an equipment problem – atop a pole, for example.
10:09 AM: Pole-top problems also can be caused by wildlife – and commenter Lamont‘s observation of a dead pigeon beneath a pole at 61st/Beach Drive indicates that’s what likely happened here.
