We’re watching the development of a significant winter storm that’s likely to affect communities across Atlantic Canada and eastern Quebec through the latter half of this weekend.
Several systems will move through the area into early next week, but the most impactful could bring heavy snows and gusty winds to a wide swath of the region.
Stay up-to-date with the latest warnings in your area, and keep an eye on road conditions if you have to head out during or after the storm.

First system arrives Sunday morning
The first system will push into Atlantic Canada through Sunday morning, bringing mostly rain to the Maritimes and Newfoundland.
Atlantic Canada Model Trends
10-20 mm of rain is expected along the southern coast of Nova Scotia with this initial system moving into the region, with heavier totals expected for folks along Newfoundland’s southern shores.
Higher elevations across northern New Brunswick and the Gaspe Peninsula will see 5-10 cm of snow from this system.
Major system arrives Sunday night
All eyes then turn toward the main act arriving Sunday night and lingering into Monday.
A large winter storm will bring a swath of heavy snow from much of central and northern New Brunswick, including Fredericton, as well as the Gaspe Peninsula. Amounts here could reach 20-30 cm.
Atlantic Canada Precip Monday
MUST SEE: Polar vortex to plunge town’s wind chills to -50 for several days
Moderate snows are in the forecast for portions of eastern Quebec, where communities east of Sherbrooke could see 10-15+ cm of accumulation from this system.
Atlantic Canada Snowfall Outlook
Wind gusts of 50+ km/h across the Maritimes could lead to reduced visibility during periods of moderate to heavy snowfall.
We’ll see a sharp cutoff in snowfall totals farther to the south where warm air will battle with the cold air pushing into the region. As a result, there remains a fair bit of uncertainty surrounding totals near the Bay of Fundy and across Nova Scotia.
A significant cooldown will follow this latter system as we begin to feel the influence of the polar vortex across the region.
