A developing winter storm is expected to bring heavy snow and strong winds to southern Nova Scotia beginning Sunday night.

Environment Canada issued a yellow‑level Winter Storm Watch early Saturday as the system approaches the province.

Southern areas could see 20 to 30 centimetres of snow, while most of Nova Scotia may receive 15 to 25 centimetres.

The agency said the storm’s track remains uncertain, but significant snowfall is possible if the system strengthens or shifts.

Northeasterly wind gusts between 50 and 80 kilometres an hour are expected on Monday.

Those winds, combined with steady snowfall, may lead to blowing snow and reduced visibility.

The agency said snow accumulation could slow or make travel hazardous, and roads and walkways may become slippery and difficult to navigate.

Environment Canada is also reminding residents may want to plan ahead in case schools or scheduled activities are cancelled.

Watches are issued when hazardous winter weather conditions are possible, and the agency said it will provide more updates as the storm approaches.
