B-C Hydro says it could still be several days before power returns to some of the communities hit hardest by Thursday’s powerful windstorm. It says 600-thousand customers have been impacted and tens of thousands remain without power. Hydro says 800 crew members are working around the clock to restore electricity, but it can be a complicated job. Among the areas that may not see full power return for days are Duncan, Nanaimo, Lake Cowichan, the Gulf Island and rural parts of Surrey and the Fraser Valley.
