A nor'easter passing over Nova Scotia led to school cancellations and a messy mix of precipitation is creating slippery road conditions across the province.

The Department of Transportation said provincial crews started working before dawn and roads were snow covered in many areas during the morning commute.

By late morning, snow along southwestern parts of the province turned to freezing rain and rain. Meanwhile, police in Cape Breton say the combination of snow and wind is creating poor visibility. 

RCMP are advising people to slow down and use caution on the roads.  

Snowfall warnings

There are snowfall warnings in effect for parts of Colchester and Cumberland counties. Environment Canada says between 15 and 20 centimetres of snow could fall before it changes to rain or ice pellets later in the afternoon. 

The storm is now tracking toward Newfoundland.

Travel disruptions

People flying in and out of the Halifax Stanfield International Airport on Monday were advised to check flight times with their airlines. There are a handful of delays and cancellations.

Some bus routes in Halifax operated on snow routes during the morning commute but have since returned to normal service.

With high winds expected on the Cabot Strait, Marine Atlantic cancelled all four of its crossings between North Sydney and Port aux Basques, N.L., on Monday. Weather permitting, the ferries will leave Tuesday morning.
