The Weather Network – Atlantic Canada braces for more snow as powerful system follows
Sunday, February 13, 2022, 8:23 a.m. — The latest track in the system is key to some snowfall totals.
A powerful low pressure system is expected to bring widespread winter effects to Atlantic Canada. The system will remain offshore, but cold air will pass over the provinces, making it a fully snow-covered event for most communities.
The heaviest snowfall for the Maritimes will occur Monday morning before beginning to taper off in the evening.
In the Maritimes, the bulk of the snowfall will fall in southern and eastern Nova Scotia, where forecasters are expecting 10 to 20 cm of snow by Monday, with the latter region likely to see some up to 25cm. Totals will drop further north, with only 5-10cm expected in Prince Edward Island and extreme southern New Brunswick.
However, coastal sections of Nova Scotia could be hit with 20cm of snow if the storm moves closer to land.
“The snow will spread west to east across Nova Scotia tonight and turn into flurries Monday evening. The light nature of the snow, combined with colder temperatures, could produce localized whiteouts on highways and exposed areas on Monday,” Environment Canada and Climate Change say in the snowfall warning for Halifax.

The greatest impacts from constant snowfall will occur in the southern Maritimes and southeastern Newfoundland, with the heaviest totals expected on the Avalon Peninsula. However, a slight change in the system’s track could reduce snowfall amounts over the Avalon Peninsula as the snow would change to ice pellets instead.
Parts of the Avalon Peninsula are most likely to pick up 30cm of snow by Tuesday morning. Areas just north and west of the Avalon can see 6-8 inches.
Windy conditions will accompany the system, with wind gusts of 40 to 60 km/h likely through Monday evening over the Maritimes. In the gulf, winds will intensify Monday afternoon, with gusts that could reach 80 to 90 km/h over the Avalon overnight Monday through Tuesday morning.
Winds will make wind chill values even colder and may reduce visibility during periods of blowing snow.
A second flurry of snow will reach Newfoundland overnight Monday through Tuesday morning as a secondary low pressure forms and moves through the region. During this wave, parts of extreme southern Newfoundland may experience brief periods of sleet or freezing rain as warm air enters the region.
After a few days of very cold weather in the middle of the week, much milder weather will return to the region on the weekend. It will also bring a widespread threat of rain as the Colorado Low enters the region.
