Schools are closed in northern and central Nova Scotia on Friday as winter returns to the region once again.

A snowfall warning is in effect, and some areas can expect more than 15 centimetres of snow.

Environment Canada says a low-pressure system is moving south of the province, bringing wet snow, rain and wind gusts of up to 90 km/h along the southwestern shore.

The snow is expected to hit Cape Breton by noon.

The Chignecto-Central Regional School Board closed all of its schools for the day and the Nova Scotia Community College campus in Truro is also shut down.

Motorists are being urged to drive with caution.

Just last weekend, Nova Scotians were shovelling out of a storm that dumped snow and ice pellets as it swept across Eastern Canada.
