MONTREAL -- Several Quebec school boards are closed as snow continues to blanket parts of the province.

Environment Canada has issued a snowfall alert, warning of low visibility and intense winds as 15 to 20 centimetres of snowfall is expected in Montreal, Laval, Longueuil, and Chateauguay.

Snowfall began late Monday evening and is expected to continue into Tuesday night.

As the snow tapers off, temperatures are likely to plummet overnight on Tuesday, descending to a low of minus 23.

Sunny skies and high winds are expected on Wednesday. A high of minus seven could fall to a blistering minus 23 with the wind chill in the morning. The afternoon is expected to warm to a tropical minus 14 with the wind chill.

Montreal Mayor Valerie Plante wrote on social media Monday that city crews were prepared to clear the city's roads through the storm.
