Environment Canada issued a winter storm watch for all of Nova Scotia at 3:33 p.m. Thursday.
Strong winds, snow and blowing snow are forecast to begin late Friday night and intensify on Saturday.
The alert was issued for the potential development of dangerous winter weather conditions in these regions. Residents are asked to monitor weather conditions and to listen for updated statements.
Environment Canada posted the following information on its website
A low pressure system will intensify as it passes near Cape Hatteras on Friday before tracking south of Nova Scotia Saturday night.
This system will give snow at times heavy, strong northeast winds and blowing snow to Nova Scotia Friday night and Saturday. These conditions will persist Saturday night and into Sunday morning for Cape Breton and Eastern Nova Scotia. While it is too early to give an accurate estimate of snowfall potential, some guidance is indicating that amounts in excess of 30 centimetres are possible for parts of Nova Scotia. Also there may be periods of ice pellets or freezing rain along the Atlantic coast starting Saturday and extending into Sunday over eastern regioins.
Strong northeasterlies and northerlies over the Gulf of St. Lawrence may also give higher than normal water levels late Saturday and into Sunday, and will push pack ice into north to northeast facing shorelines.
