The heaviest snowstorm of the season is set to produce significant snowfall from Maine to New Brunswick and Newfoundland through Friday.
A storm system will quickly intensify off the coast of Maine on Thursday and will track eastward to the south of Newfoundland on Friday.
Most areas from Maine to Newfoundland will start out the event as rain. As cold air quickly funnels southward across the area, rain will change to a heavy, wet snow.
"Precipitation will begin in the form of rain across much of Maine before changing to a wet snow Thursday afternoon through Thursday night," AccuWeather Meteorologist Dan Pydynowski said.
This storm will exit portions of eastern Quebec, Maine and New Brunswick on Thursday night before setting its sights on Newfoundland late Thursday night into Friday afternoon.
"The storm track will be such that precipitation in Halifax and most of Nova Scotia will be in the form of rain," Pydynowski said.
This storm is expected to track quickly to the east but still produce a band of heavy snow with high snowfall rates.
Snowfall rates could reach 2 inches (5 cm) per hour in the heaviest bands of snow.
Travel will become dangerous as roads will quickly become slushy and icy as temperatures fall well below freezing.
The heaviest band of snow is expected to set up from portions of northern Maine through central New Brunswick, northern Prince Edward Island and across southern Newfoundland. Snow totals could reach 12 inches (30 cm).
Locations within the swath of accumulating snow through Friday include Quebec City, Quebec; Caribou, Maine; Saint John, Moncton and Fredericton, New Brunswick; Charlottetown, Prince Edward Island; and Gander and St. John's Newfoundland.
The weight of the snow could lead to downed trees and sporadic power outages.
Strong winds will accompany the snow, mainly across the Canadian Maritimes. Winds could gust up to 40 mph (64 km/h) at times, leading to blowing and drifting snow.
Much of the region will remain dry through the weekend following this storm.
While smaller snowstorms have struck portions of the Canadian Maritimes so far this season, much of northern Maine has been quiet.
"For much of northern Maine, this will be by far the largest and most significant snowfall of the season thus far," Pydynowski said.
"Caribou, Maine, has only had 4.1 inches of snow through Dec. 2 and the normal snowfall is around 13 inches."
Caribou will be located to the north of the heaviest band of snow but could still receive more snow than the city has had so far this season.
