Record snowfall in progress on the East Coast as event perseveres

Heavy snowfall has been taking up multiple days of residency across the East Coast, adding up to major, potentially historic totals for some areas through Monday.

And, when combined with high wind gusts, the snow has made travel quite treacherous, and even impossible for many locales, since the start of the storm. The Nova Scotia government and RCMP are urging people to stay off the roads, unless their travel is essential. Visibility will be suddenly reduced to near zero at times in heavy snow and blowing snow.

Major road closures have occurred Sunday across Nova Scotia as a result, along with numerous collisions.

As well, there are more than 4,000 Nova Scotia Power customers are in the dark as of Sunday morning. That will likely fluctuate through the weekend.

Confidence is greatest that Cape Breton and parts of Newfoundland will see the most substantial snowfall totals by the time snow finally stops early next week.

Preliminary snowfall totals as of 8 a.m. local time Sunday include more than 40 cm at Halifax airport, more than 50 cm in Sydney and more than 36 cm in Charlottetown. However, there are unconfirmed reports around Sydney of accumulations of 70+ cm of snowfall.

East Coast on track to see substantial snowfall

An unusual stalling low-pressure system will be dancing off the coast of Nova Scotia, bringing the highest snowfall totals seen in two decades for a big swath of Atlantic Canada.

A low-pressure system is going to hit the pause button and stall just southeast of Sable Island for 48 hours. An arctic high over Labrador will supply the cold air, which will be a blockbuster snowfall event for those in the eastern Maritimes and central Newfoundland.

Conditions improve for Halifax, N.S., but become even more intense across Cape Breton and those communities along the Northumberland Strait. While snowfall rates remain generally below one centimetre an hour for Halifax, they will be as high as 5 cm an hour across Cape Breton.

Snow was beginning to pile up in Sydney, with over half a metre reported through Sunday morning, with locally higher amounts documented. An additional 50+ cm of snow is forecast for the area, meaning this is likely going to be the most significant snowfall event in recorded history for Cape Breton.

East of Truro, along Highway 104, is where the totals really pile up past half a metre of snowfall. Travel will be impossible throughout the region on Sunday with intense drifts and zero visibility.

The Cape Breton region, including Sydney, and Glace Bay, is forecast to have more than 100 cm of snowfall accumulation. With these snowfall rates forecast, a long-duration blizzard is likely to linger through much of Sunday.

When all is said and done, some regions are likely to record up to 150 cm of snowfall accumulation in localized spots.

Although the Avalon is a tricky forecast with two waves of snowfall forecast for St. John’s, resulting in more than 20 cm of snow forecast through Tuesday. Farther inland, and west along the Trans-Canada Highway, expect 20-40 cm of snow from Gander to Deer Lake.

Gusty winds of 60-80 km/h will accompany the snowfall across Newfoundland, leading to a risk for near-blizzard conditions during periods of moderate to heavy snowfall.

Much like we’ll see in the Maritimes, travel will be difficult if not impossible during these whiteouts.

The storm will eventually weaken and depart the area later Tuesday.
