Powerful winter storm wallops southern Manitoba before moving into Ontario

A powerful storm that dumped up to 20 centimetres of snow on southern Manitoba overnight has moved into Ontario.

But Environment Canada says gusty winds are still causing blowing snow and poor visibility in some areas of the prairie province, and temperatures will remain around -20 degrees Celsius.

The agency says the blizzard led authorities to close several roads, including the Trans-Canada Highway between Winnipeg and the Saskatchewan border.

Meanwhile, a storm warning has been issued for parts of northern Ontario, where up to 30 centimetres of snow are expected by tonight.

The warning covers areas including Sandy Lake, Kenora, Sioux Lookout and Fort Albany, while others — such as Moosonee, Manitouwadge and Nakina — are expecting freezing rain.

Motorists are advised to take care on the roads and delay their travel plans if conditions appear too treacherous.
