Most of Bainbridge Island remained without power Thursday evening following a windstorm that swept through Western Washington Dec. 20.

PSE reported 845 separate outages and 118,000 customers without power at 7 p.m. Thursday.

On Bainbridge, more than 8,000 PSE customers were without electricity Thursday evening.

Multiple roads across the island were closed through the day and into the evening due to fallen trees and power lines.

Traffic signals on Highway 305 went dark across the island just before noon, leading to a massive traffic backup from the Agate Pass Bridge south to the intersection at Sportsman Club Road.

No injuries were immediately reported, although a Facebook post the North Kitsap Community page showed a tree that had fallen onto a truck on Miller Road Thursday. The driver was reportedly shaken but not injured.

Long lines formed at Bainbridge gas stations quickly after power went out before noon. Many businesses on the island closed for the day and sent their employees home.

Residents in neighborhoods across Bainbridge began cleanup efforts — moving branches and cutting up fallen trees along area roads — before the strong winds diminished.

The power outage across Bainbridge also led to the cancelation of the Thursday night meeting of the board of commissioners for the Bainbridge Island Metropolitan Park & Recreation District.

PSE said the winds “caused damage to more than 800 locations around our service area” and 165,000 customers were without power at 3 p.m.

The utility said it was bringing in out-of-area crews to assist in the restoration efforts, which stretch along the I-5 corridor from Centralia all the way to the Canadian border.
