The old saying about March, that it "comes in like a lion and goes out like a lamb," seems to be coming true this year in Quebec.

Environment and Climate Change Canada (ECCC) has issued a snowfall warning for much of southern Quebec, from Laval through Montreal and the South Shore to the Châteauguay Valley and Eastern Townships.

A total of 15 to 20 centimetres of snow is expected beginning overnight tonight. Conditions are expected to improve late in the day on Saturday with snow ending Saturday evening in the Townships.

Gatineau is also under a snowfall warning, although they can expect a little less there: about 15 centimetres in all.

The weather service is warning people to be prepared for "quickly changing and deteriorating travel conditions. If visibility is reduced while driving, slow down, watch for tail lights ahead and be prepared to stop."

Air Canada has warned customers to check their flight status before leaving for the airports in Toronto, Ottawa and Montreal.

Flights in and out of Toronto delayed until Saturday

WestJet proactively cancelled all scheduled flights to and from Toronto Pearson International Airport on Friday, ahead of the storm.

Flights in and out of Toronto are expected to resume Saturday morning, the airline said in a service update.

"At this time, scheduled operations to and from Toronto are expected to resume ... at a reduced capacity, contingent on weather conditions improving as forecasted," WestJet said in a release.

WestJet said it would continue to monitor storm conditions and make operational changes as required.

It advised guests travelling to or from Toronto to check the status of their flights before leaving for the airport.

The storm is expected to hit Toronto on Friday evening.
