Fortunately, none of the overnight road accidents caused injuries.
Transports Québec spokesman Mario St-Pierre said the most affected part of the city appeared to be Highway 40 in the West Island.
There, he said, the highway's proximity to open fields caused the formation of black ice on some parts of the road.
St-Pierre cautioned people to drive more slowly and to be aware roads near open spaces and above ground level may be particularly dangerous, citing stronger winds and therefore colder temperatures.
Although the law in Quebec only requires drivers to install their winter tires by Dec. 15, he said it would be a good idea for drivers to get a head start.
First snowfall accumulation
Approximately five centimetres of snow is expected to fall on the Montreal region by Monday morning.
Up to 10 centimetres could fall on more eastern parts of the province and in the Laurentians. Mountainous regions in southern Quebec could see upwards of 15 centimetres.Suggest a correction
