Start: 2017-10-22T20:00
End: 2017-10-23T07:00
Location: Washington

October 22 to 23, 2017 · NWS OTX · 1 event in 1 county or zone

During the evening of October 22nd strong winds brought down numerous trees and caused power outages in and around the town of Stehekin in the north Cascades. The damage was very localized and it is suspected that terrain channeling of winds through the Stehekin Valley created a local corridor for very strong non-thunderstorm wind speeds.
