Powerful winds to roar over Atlantic Canada as storm strengthens
A wintry storm moving through Atlantic Canada will rapidly strengthen on Monday, giving way to very strong winds throughout the region
A snowy and icy mess that blanketed the Maritimes on Sunday will move into Newfoundland through the overnight hours, bringing an impactful wintry mix to the island.
Expect powerful winds to build over the entire region through the day on Monday as the storm rapidly deepens over the Gulf. Gusts could peak well over 100 km/h in some vulnerable areas.

Wintry mess continues overnight
Precipitation will begin to wind down across the Maritimes through the overnight hours as the bulk of our wintry storm moves into Newfoundland.
However, heavy snow will develop for extreme eastern New Brunswick, as well as Cape Breton, through Monday morning as the system strengthens over the Gulf.
Periods of snow that arrived in Newfoundland on Sunday evening will give way to ice pellets and freezing rain as warmer air aloft pushes into the region. Significant freezing rain is possible across central Newfoundland before transitioning back to snow Monday afternoon.
The Avalon, Bonavista, and Burin Peninsulas will all transition to rain by Monday morning, with stubborn freezing rain lingering in Gander.
Western Newfoundland can expect 10-30+ cm of snow from this system, with less than 5 cm of total accumulation in the forecast for the Avalon.
Very strong winds build into Monday
Our storm system is expected to rapidly deepen below 960 mb by Monday afternoon as it crosses northern Newfoundland, resulting in powerful wind gusts throughout all of Atlantic Canada.
Gusts of 60-80 km/h will be common across New Brunswick and Nova Scotia. Cape Breton could see gusts of 80-120 km/h.
Folks across Newfoundland may see gusts of 90-130 km/h, which could cause damage to trees and power lines. The strongest winds will occur in exposed coastal communities on the island’s southern shores.
