9:05 PM: One spot of easternmost West Seattle is part of a big power outage that otherwise is mostly southeast of West Seattle. The City Light map shows more than 3,400 homes/businesses out in eastern White Center, Top Hat, and parts of Burien. No word yet on the cause or estimated restoration.

9:31 PM: The outage map has updated and the WC/TH section has apparently been fixed, leaving a section of Burien still out.

10:18 PM: City Light says a tree is to blame and those still without power might not get it back until 4:30 am or so.
