Several parts of Atlantic Canada are digging out Monday after a powerful nor'easter carried a potent mix of snow, rain and ice pellets into the Maritimes.

Meanwhile, the intense low-pressure system that blasted the East Coast with wintery weather over the weekend has moved over central Newfoundland and is tracking eastward.

Environment Canada anticipates the storm will push past the Labrador Sea on Tuesday.

As it churns away, the agency predicts the storm will taunt the province with wet, heavy snow and wind gusts of up to 90 km/h. Up to 50 centimetres of snow is expected to fall in some parts of Newfoundland and Labrador, adding to weekend totals.

The storm system had moved into Atlantic Canada on Sunday after hitting the U.S. state of Maine with a blast of wintery weather. Residents struggled to clear driveways and walkways as the nor’easter dumped nearly 40 centimetres of snow over parts of southern New Brunswick.

In Nova Scotia, the storm proved to be temperamental as it alternated between snow and rain.

Resident Walter Farmer said the cocktail of precipitation meant the snow on his driveway became too wet to clear with a snowblower. Instead, he tried to clear the snow with a shovel.

“It’s raining, but I wanted to try to get it moved out of the way before too much water got in,” Farmer told CTV Atlantic on Sunday.

By day’s end, Nova Scotia had received about 20 centimetres of snow. Though the snowfall had tapered off Monday, a wind warning remained in effect for the province.

Environment Canada has cautioned that gusts of wind combined with fresh snow could result in poor road conditions, including the possibility of white-out situations.

More than a dozen vehicle accidents were reported across Nova Scotia Sunday.

Motorist Don Campbell said he witnessed one fellow driver skid across a roadway.

“We were only doing around 40 kilometres and she just took to the slide and she wouldn’t straighten out,” he said, adding: “she went in the ditch quite gently.”

The inclement weather was also blamed for a number of flight delays and cancellations in the Maritimes over the weekend. The Halifax International Airport’s online departure board glowed red Sunday with a number of cancellations, as the storm tracked up the Atlantic coast.

As of 10 a.m. Monday morning, operations appeared to be picking up again at the Halifax airport and St. John’s International Airport. Online departure boards for both airports posted a number of morning delays, but few cancellations.

Still, a weather advisory urging travellers to double-check the status of their flights before leaving home remained on the Halifax airport’s website on Monday.
