SEATTLE (AP) — About 100,000 customers remained without power following a winter storm that swept through the western Washington.

Puget Sound Energy reported about 86,000 customers without electricity as of Monday afternoon and Seattle City Light listed about 10,000.

More than 100 school districts cancelled classes and dozens of flights were cancelled at Seattle-Tacoma International Airport after snow and ice blanketed the Puget Sound area. A winter storm watch was in effect through Monday afternoon.
