All of Nova Scotia and Prince Edward Island, as well as parts of Newfoundland and Labrador are under a special weather statement as a low-pressure system tracks toward the region from the east coast of the U.S.
On Friday, those areas could receive as much as 10 to 15 centimetres of snow, the national weather service says. However, Environment Canada says there's still much uncertainty about how much snow is likely to fall.
CBC meteorologist Peter Coade says a "very cold arctic high-pressure cell moving east through central Quebec and Labrador that has kept disturbances," such as the system that slammed Boston, "at bay as they pass by to our south."
"This area of high pressure will move off to the east over the next couple days and we shall lose this protective covering," says Coade.
An intense disturbance will be passing by to the south again Wednesday and bring about a fairly strong wind from the northeast as well as increasing amounts of cloud that will likely produce a few flurries but that should be about the only effect on the Maritimes.
The nor'easter heading to Atlantic Canada Thursday evening and Friday morning likely won't have much of an effect on the already snow-ravaged region of southern New Brunswick. Parts of that area received as more than a metre of snow in a short amount of time.
"This storm will continue out of the area Friday night so that Saturday we can expect a return to sunshine," says Coade.
"However, there are indications of yet another storm developing along the coast and intensify as it tracks in our direction to become a nor’easter for our area on Sunday. Earliest indications are that the Sunday nor’easter will produce more snow in more areas."
