As Quebec residents wake up to a snowy morning commute, thousands are without power across the province.

Wednesday's heavy, wet snow fell on power lines and tree branches, knocking out power to more than 30,000 homes and businesses in Quebec.

The Montérégie region was hit the hardest by power outages, where about 20,000 clients are in the dark.

Hydro Québec said it's not clear how long it will take for power to be restored.

Montreal was blanketed with about 16 centimetres of snow yesterday, and Environment Canada is forecasting about 4 more centimetres will fall by end of day Thursday.

Quebec City could see up to 12 centimetres of snow today and overnight.
