BC Hydro spokesman Bob Gammar says the storm knocked down power lines in 150 locations as far west as Kitwanga, and all the way east to the Alberta border.
At the height of the storm around 10 p.m. PT Monday, about 22,000 customers were without electricity. By 9 a.m. PT about 16,000 customers were still without power, according to the BC Hydro website.
The utility expects power to be restored to most customers sometime between 2 p.m. and 6 p.m. this afternoon, but Gammar says some people in outlying areas may be without power into early this evening.
The storm also knocked out power at a Blue Rodeo concert in Dawson Creek last night.
But several hundred fans got their money's worth when workers at the Encana Events Centre fired up generators, giving the band enough power to play a 100 minute acoustic concert.
