On Monday, light snow and gusty winds hit Atlantic Canada. The cold front is just the beginning of what's shaping up to be a wintry week for eastern Canada.

Forecasters are keeping their eye on a  Nor'easter that's expected to impact Atlantic Canada Wednesday.

"This will likely be a winter storm with significant snowfall, accumulating along with blowing snow being a large issue," warns Weather Network meteorologist Monica Vaswani.

Snow will move into the Maritimes early Wednesday morning and continue through the night, reaching as far west as western New Brunswick, PEI and Nova Scotia.

"There is a slight chance of mixing along the Atlantic shorelines of Nova Scotia," says Weather Network meteorologist Dayna Vettese.

"Gusts between 40 and 60 kilometres per hour are expected across the Maritimes, except for north-facing shores. In those areas, gusts could reach as high as 100 km/h."

By the time all is said and done, 15-25 cm of snow is expected in Nova Scotia, PEI and New Brunswick.

STRONG WIND, FREEZING RAIN POTENTIAL FOR NEWFOUNDLAND

The storm will hit Newfoundland mid-day Wednesday and continue through to Thursday afternoon.

"There will be a risk of freezing rain for the Avalon and Burin Peninsulas, with a changeover to rain late day Wednesday," Vettese says.

Wind gusts as high as 110 km/h are possible Wednesday evening into Thursday morning.

Up to 10 cm of snow is expected to accumulate in the Avalon Peninsula. The rest of Newfoundland could see up to 25 cm, with locally higher amounts possible.

WHAT IS A NOR'EASTER?

"A Nor’easter is named after the winds that occur during the storm," explains Weather Network meteorologist Matt Grinter.

"Strong winds come from the north-east, and with the amount of snow generated, these storms usually cause conditions of blowing snow and white out conditions."

Nor'easter tracks are typically off the U.S. coast and tend to hit New England and Atlantic Canada being the hardest hit.

"The development of a Nor’easter occurs when there is a sharp contrast in cold dry air coming down from north-eastern Canada and the Warm Gulf stream ocean current," Grinter adds.

The current mixing of the warm ocean current and cold air creates favourable conditions for the development of the upcoming system, he adds.

Because the track of this system will mostly be offshore, the winds will be coming from the north east, making this a 'classic' Nor'easter.
