Nearly half of Bainbridge Island lost power Wednesday afternoon as gusty weather swept through Puget Sound.

A total of 3,849 customers of Puget Sound Energy lost power — in an area stretching from the Grand Forest to South Beach — just after 2:30 p.m. Oct. 15.

The outage area included all of the island south of Eagle Harbor.

Another blackout was reported on the north end of the island, near Manzanita, just after 3 p.m. Just three homes there were affected, PSE reported.

PSE expects to have power restored by 5 p.m. Oct. 18 on the South End of Bainbridge.

The strength of the winds was a bit of a surprise. The National Weather Service issued a wind advisory for much of the Puget Sound region early Wednesday afternoon.

The advisory will remain in effect until 11 p.m. Wednesday.

The National Weather Service said southernly winds of 20 to 30 mph — with gusts up to 45 mph — are expected.

PSE said more than 12,000 homes and businesses were without power in its Western Washington service area Wednesday afternoon. Outages were also reported Wednesday afternoon in Suquamish and Indianola.
