Threat for dangerous travel with blowing snow over Atlantic Canada Wednesday

Posted on October 31, 2023, 2:49 p.m

Eyes are on a midweek system that threatens more widespread snow over Atlantic Canada, with strong winds, which could make travel difficult and whiteout conditions.

After the first taste of winter with a flurry or two of snow in parts of Atlantic Canada on Monday, eyes are now on another system for midweek, one that threatens more widespread snow.

This will be the first snowfall of the season for parts of southern Nova Scotia, including Halifax, this time.

Drivers are urged to plan a difficult winter trip, especially with this likely to be the first dose for many motorists.


Low pressure will develop over the Atlantic and rapidly intensify as it tracks south of the Maritimes on Wednesday, then moving toward the Avalon Peninsula on Wednesday night and Thursday. This will put Nova Scotia and central Newfoundland in the target for wet snow accumulation and breezy conditions.

This forecast will naturally be in flux as temperatures hover around the freezing mark, and small swings in the track will make all the difference.

Nova Scotia is first. By Wednesday morning, the snow will move into the southwest, building in Halifax and east during the day. The immediate coasts can see a mix of snow and rain for periods of time, limiting the accumulations here. But further inland, and at higher altitudes, there is a better chance for a white coating on the grass, with 5+ cm possible.
