High-impact nor’easter to bring heavy snow and high winds
A swath of heavy snow and high winds will wallop the Maritimes and Newfoundland through Monday
A large and disruptive nor’easter will sweep through Atlantic Canada to kick off the new workweek, bringing widespread snowfall and gusty winds to much of the region.
Expect travel issues during your Monday morning commute across the Maritimes and Newfoundland. High winds in excess of 100 km/h may buffet St. John’s during the storm.
DON’T MISS: Second half of January looking much colder across Canada
High-impact nor’easter peaks into Monday
A sprawling low-pressure system developing off the U.S. East Coast will reach Atlantic Canada as a full-blown nor’easter overnight Sunday into the day Monday.
This system’s influence extends thousands of kilometres away, bringing rare snow to Florida and a spell of damaging winds to southern Mexico.
Heavy, wet snow will continue spreading over the Maritimes during the overnight hours Sunday. The heaviest snowfall in the Maritimes is forecast to arrive through the pre-dawn hours Monday. Conditions will improve later Monday morning as the system lifts north toward Newfoundland.
Expect dangerous travel conditions across central and western Newfoundland throughout the day Monday as heavy snow and a wintry mix continue across the island. Travel will be especially risky along the Trans-Canada west of Clarenville to Corner Brook.
Significant totals for some communities
The precise track of the nor’easter will determine where the heaviest bands of snow set up as they traverse the Maritimes and Newfoundland.
Forecasters expect a swath of 10-20+ cm of snow to cover much of Nova Scotia, eastern New Brunswick, and eastern Prince Edward Island. Wet snow may reduce totals in coastal Nova Scotia, including around Halifax.
Central and western Newfoundland are on track for 15-30 cm of snow through Monday. The heaviest totals are expected in western Newfoundland and at higher elevations.
The heavy, wet snow may bring down trees and power lines across the region.
Wind-swept rain will pound the Avalon
Precipitation that begins as snow across the Avalon Peninsula will quickly transition over to a wintry mix, then plain old rain, as warm southerly winds flow into the area.
Winds will ramp up in a hurry through the day Monday as the nor’easter intensifies. Gusts in excess of 100 km/h are forecast for the Avalon, Burin, and Bonavista Peninsulas.
St. John’s could endure several hours of 90-100 km/h wind gusts on Monday afternoon and evening.
