Wintry conditions continue to sweep parts of Eastern Canada, Maritimes

Canada's common cold cranch is continuing into tues after a overwinter force slammed Ontario and Quebec, wreaking havoc on the roads and leaving tens of thousands without power.

Millions remain under yellow and orange weather warnings from Environment Canada as storms sweep through multiple provinces, stretching from eastern Ontario to the Atlantic region.

In Ontario and Quebec, storm fronts brought freezing rain, blowing snow and strong winds, leaving tens of thousands without power at one point.

The federal weather agency says some areas northeast of Quebec City and into northern New Brunswick could see between 15 and 40 centimetres of snow, along with high winds.

Much of Canada has been blasted with a number of weather systems over the last week, ranging from blizzards and cold snaps to freezing rain.

In B.C., some residents were left stranded after heavy rainfall washed out a section of Highway 16 in Haida Gwaii, connecting the north and south parts of the island.

Meanwhile, a strengthening bomb cyclone is barrelling its way across the northern United States, unleashing severe winter weather in the Midwest and aiming at the East Coast.

Environment and Climate Change Canada is calling for extreme winds — up to 140 km/h — in northern Nova Scotia, particularly the northeastern tip of the province. Much of the Atlantic region is under yellow warnings for freezing rain that could in some places lead to flooding, the agency said.

Heavy rain and melting snow melt wash out roads, force bridge closures in Haida Gwaii, B.C.

Meanwhile, Air Canada cautioned on its website that flights to and from Montreal, Ottawa and both Toronto airports could still be affected Tuesday, as the airline recovers from a weather-related backlog.

It comes after a number of flights were cancelled or delayed in Montreal, Toronto, London, Ont., Halifax and St. John's on Monday.

In London and the Lake Huron and Georgian Bay regions, Environment and Climate Change Canada is warning of continuing blizzard conditions with "dangerous snow squalls," advising residents to beware of prolonged disruptions to transportation, services and utilities.

"Lake-effect snow off Lake Huron continues. Widespread blowing snow resulting in near-zero visibility remains the primary concern due to northwesterly winds gusting 50 to 70 km/h," the agency said, adding that the winds are expected to ease by Tuesday evening.
