Grease up the shovels and prime the snow blowers because much of the province is going to see a substantial snowfall Monday through Tuesday.

The system in question is a nor'easter type of low that is now gaining strength off the coastline of the Carolinas.

The low will be tracking just outside of Sable Island which keeps Nova Scotia in the north and northwestern area of the storm which is the prime snowfall region.

The snow may begin in the tri-counties as early as near noon tomorrow but will spread across the province through the afternoon and early evening.

Heaviest snow Monday night

The heaviest snow is expected Monday evening and night though a weaker low following in behind the main system may bring an additional snowfall late Tuesday into Wednesday morning.

Monday through Tuesday morning snow as much as 15 to 20 centimetres for the Annapolis Valley, Hants, Cumberland and Colchester counties and 20 to 30 centimetres for the rest of the province though locally higher amounts of up to 40 centimetres is possible for communities on the Atlantic coastline and in Cape Breton. 

Northeast winds gusting 50 to 70 km/h will accompany the snowfall so extensive blowing and drifting snow is expected.

Winter storm watch

Environment Canada has issued a winter storm watch for all of Nova Scotia.

The national weather service said strong northeast winds will create blowing snow and reduce visibility. It warns that could make travel hazardous and contribute to transportation delays.

The system is expected to pass south of the province Monday night, leading to higher-than-normal water levels and rough surf along Nova Scotia's Atlantic coast.

Despite the winter storm watch, the weather on Sunday looks good. Much of the province will have a mix of sun and cloud with a chance of flurries or showers.
