Winter storm and extreme cold warnings blanket Maritimes

Environment Canada has issued more weather warnings for the Maritimes as another nor'easter bears down on the region. 

Nova Scotia under winter storm, rainfall warnings

The system is expected to bring a mixed bag of precipitation to the Maritimes, with heavy snow across much of Nova Scotia, New Brunswick and P.E.I. beginning late Monday morning. 

The following Nova Scotia counties are under a winter storm warning:

- Annapolis

- Antigonish

- Colchester

- Cumberland

- Digby

- Hants

- Halifax

- Inverness

- Kings

- Lunenburg

- Pictou

- Queens

- Shelburne

- Victoria

- Yarmouth

Those areas can expect anywhere between 15 and 45 centimetres of snow. With strong winds, visibility will likely be an issue for those out on the roads. 

"Surfaces such as highways, roads, walkways and parking lots may become difficult to navigate due to accumulating snow. Prepare for quickly changing and deteriorating travel conditions," says the Environment Canada weather warning.

As the system moves northeastward, it's expected the snow will change to rain in Nova Scotia on Monday evening with a period of ice pellets in between. 

Nova Scotia counties under a heavy rainfall warning are Guysborough, Halifax, Lunenburg, Queens, Richmond, Shelburne, Cape Breton and Yarmouth counties. 

While many of those regions will get heavy snow, Environment Canada is also warning that these areas may see an additional 30 to 50 millimetres of rain. Localized flooding is possible in these areas as the frozen ground is unable to absorb all of that water.

"Another brief shot of snow is expected Tuesday morning in the wake of the system. Conditions will gradually improve through the day on Tuesday as the low moves away," says Environment Canada.

Blizzard, extreme cold warnings for New Brunswick 

The system bringing a mixed bag of precipitation to Nova Scotia is prompting blizzard and extreme cold warnings for New Brunswick.

Blizzard warnings are issued when widespread reduced visibilities of 400 metres or less are expected for at least four hours.

All counties in that province, expect Campbellton, Restigouche, Edmundston, Madawaska, Grand Falls, and Victoria are under a blizzard warning. 

Those areas are expected to receive another 40 centimetres of snow, on top of the snow that fell during last week's storms. 

Extreme cold warnings are also in place for almost all of New Brunswick. 

Moderate to strong northeasterly winds and bitterly cold air are combining to give extreme wind chill values between –39 C to –35 C Monday morning. It is expected to warm up a bit as the day goes on.

The national weather service urges anyone out in the cold to dress appropriately to avoid hypothermia and frostbite.

P.E.I. under blizzard, winter storm and extreme cold warnings

Those same extreme cold warnings issued for New Brunswick extend to all of Prince Edward Island this morning. 

Prince County is under a blizzard warning with blowing snow and as much as 40 centimetres likely to fall. 

Both Kings and Queens counties are under winter storm warnings with as much as 30 centimetres expected to fall by Tuesday morning. 

Tuesday back to fair weather, but not for long

CBC meteorologist Peter Coade says the nasty weather will taper off Tuesday, but not for long.

"A ridge of high pressure will move across the Maritimes later on Tuesday, bringing a return to fair weather – but not to last," he says.

"Another disturbance will swing into the region later on Wednesday with some snow and/or rain for Thursday. As you can imagine, temperatures will be on another roller-coaster this week, starting out with extreme cold warning for much of the area."
