A winter storm early next week could bring heavy snow and strong winds to most of Nova Scotia, according to Environment Canada.

A special weather statement was issued on Saturday that 15 to 25 centimetres of snow is possible from Sunday night through Tuesday morning.

Environment Canada said the system is still developing and its track remains uncertain, but the potential exists for significant snowfall across the province.

The agency explained northeasterly wind gusts between 50 and 70 kilometres an hour are expected on Monday, which could lead to blowing snow and reduced visibility.

A winter storm watch is already in place for southern Nova Scotia.

Snow accumulation may slow or make travel hazardous, and roads and walkways could become slippery.

The agency is also advising people to plan ahead in case schools or scheduled activities are cancelled.
