It's another messy mix of winter for southern Quebec. On Monday evening, blowing snow switched over to ice pellets and freezing rain.
Environment Canada issued warnings for the Greater Montreal Area, the Eastern Townships, Lanaudière, the Laurentians, as well as the St. Lawrence, Ottawa and Richelieu River valleys.
Much of Eastern Quebec is under winter storm warning, too.

The federal weather agency says between 10 and 15 millimetres of freezing rain could fall over those areas, starting Monday evening and continuing into Tuesday.
"Surfaces such as highways, roads, walkways and parking lots will become icy, slippery and hazardous," the warning said.
"Consider postponing non-essential travel until conditions improve. Ice buildup may cause tree branches to break."
Delays and cancellations
Pierre Elliott Trudeau International Airport posted dozens of delays and cancellations for Monday night and Tuesday. The airport has issued a notice to those travelling to check their flight status before heading to the airport.
School boards, including the English Montreal School Board and the Commission scolaire de Montréal, said they are monitoring the situation and will decide early Tuesday morning whether classes will be cancelled.
However, students at Académie Michèle-Provost in Montreal will have a day off. The school announced on Facebook that it will be closed Tuesday due to weather conditions.
