Atmospheric river brings a soggy weekend to Atlantic Canada
Grab the umbrella, Atlantic Canada, because this weekend is going to be wet. Some areas are potentially in line to see as much as 75-80 mm of rainfall, or more.
A stretch of very wet weather is heading to Atlantic Canada this weekend, but will come with a brief warm-up on Friday.
Multiple developing low-pressure systems will track into the region, bringing periods of widespread rain through the weekend and beyond. A potential for thunderstorms could enhance rainfall totals, increasing the threat of localized flooding.

Weekend: Soaking rains coming for Atlantic Canada
A trough over Ontario and Quebec, as well as a high-pressure ridge over the Atlantic Ocean is creating a narrow pathway for sub-tropical moisture to travel along, creating an atmospheric river as a result.
Heavy rainfall across southwestern Nova Scotia will start on Friday, filling into the rest of the province by the evening. Embedded thunderstorms are expected through the evening, as well, potentially increasing the rainfall amounts.
There is also a chance for parts of New Brunswick to see 20-degree temperatures make a brief return on Firday as a warm southerly flow moves over the province. Fredericton has only recorded 20-degree weather in November eight times in recorded history, with the most recent being Nov. 6, 2024.

By Saturday, all of the Maritimes will be encompassed in the rainfall, which may be heavy at times.
By Sunday, the rainfall should lift into Newfoundland, briefly encompassing all of Atlantic Canada before gradually easing across the Maritimes later in the day.
Rain totals will be quite substantial across much of the Maritimes, and into southwestern Newfoundland. Amounts of 50-80 mm are expected for much of Nova Scotia, southern New Brunswick, and the Burgeo shores.
Meanwhile, 30-50 mm are forecast for central New Brunswick and PEI.
