The new year is starting off with a bang in parts of the Maritimes with the arrival of a major winter storm. While Newfoundland will feel the brunt of the storm, Eastern Nova Scotia and Prince Edward Island can expect a significant amount of snow and strong winds throughout the day Sunday and into Monday. The rest of the Maritimes, meanwhile, will experience little to no impacts from the storm.
The storm has been rapidly intensifying during its approach towards Atlantic Canada throughout the day Saturday, meeting the criteria of a bomb cyclone (a drop in internal pressure of at least 24mb in 24 hours).
The western edge of the storm will briefly skim along the far eastern coast of Cape Breton Island early Sunday morning as the storm surges north towards Newfoundland, bringing snow and wind gusts of 70-90km/h. The storm will continue to grow in size as it gains latitude, which will push the snowfall and intense winds deeper into Cape Breton as the morning progresses.
By the mid-morning, the storm is expected to shift and start moving along a more northwesterly track, which will bring the snow and strong winds into Eastern Mainland Nova Scotia, across Prince Edward Island, and briefly to the eastern tip of the Acadian Peninsula. Blowing snow will greatly reduce visibility across the area throughout the day and could even lead to blizzard conditions.
The storm will gradually lose momentum later in the afternoon before completely stalling for several hours in the late evening and overnight. This will result in the impacted areas of PEI and Nova Scotia seeing snow quickly accumulate and the strong winds continuing while also limiting how far westward into the rest of the Maritimes that the snow spreads.

At around sunrise on Monday morning, the storm will start to fall apart, with the snow tapering off and the winds dying down across PEI and Mainland Nova Scotia throughout the morning. By the early afternoon, the only snow falling will be in the Cape Breton Highlands, where it will continue until the late evening.
The Cape Breton Highlands will be the hardest hit area and heavy snow is expected to fall for 24 hours at up to 5cm/hr, leading to over 50cm of accumulation here. This area will also see the strongest wind gusts from the storm, up to 100km/h, making travel very treacherous and possibly resulting in power outages.
