Southern Quebec could face a significant winter weather event this week, with forecasters warning that prolonged freezing rain may disrupt transportation, damage infrastructure and lead to power outages across several regions.
Environment Canada Issues Special Weather Statement
Environment Canada has issued a special weather statement covering large parts of southern Quebec, including Greater Montreal, Montérégie, Outaouais, the Laurentians, Lanaudière, Mauricie, Centre-du-Québec and the Quebec City area.
Forecasters say a weather system expected to arrive overnight Tuesday into Wednesday could bring between 20 and 30 millimetres of freezing rain. The precipitation may continue through much of Wednesday, creating hazardous conditions across the region.
Meteorologists warn the event could significantly affect daily activities, with possible delays or cancellations affecting transportation and other services.
Why the Storm Is Considered “Critical”
Meteorologist Giselle Dookhie said the main concern is the duration of the freezing rain, which could last up to 24 hours.
“The reason we’re describing it as potentially critical is the length of the event,” she said. “With freezing rain persisting through much of the day, impacts are likely to increase as the system progresses.”
Extended periods of freezing rain can quickly build up thick layers of ice on exposed surfaces such as roads, trees and power lines. In severe cases, the added weight can cause branches to snap or electrical lines to sag and break.
Risk to Trees and Power Infrastructure
Heavy ice accumulation could place significant strain on tree branches and power lines.
“Think about the weight building up on tree limbs,” Dookhie explained. “Branches can break, and that can lead to power outages in affected areas.”
The warning comes just weeks after residents in Montreal’s west end experienced a prolonged blackout during a stretch of extreme cold. Aging equipment belonging to Hydro‑Québec failed during the cold snap, leaving many households without power. Two deaths were reported during that outage.
Strong wind gusts expected during the storm could worsen conditions by destabilizing ice-covered trees, increasing the risk of falling branches.
Travel Disruptions Likely Across Southern Quebec
Road conditions could deteriorate rapidly as freezing rain accumulates on highways and city streets.
Environment Canada says driving conditions may become particularly dangerous Wednesday afternoon and evening, when ice buildup is expected to peak.
Dookhie suggested that people consider staying off the roads if possible.
“If you’re able to work from home on Wednesday, that may be the safer option,” she said.
Officials with Transports Québec are urging motorists who must travel to slow down and maintain a safe distance between vehicles.
Such storms are not uncommon in eastern Canada. Major ice events, including the devastating 1998 Ice Storm, have shown how prolonged freezing rain can cripple infrastructure across Quebec and neighbouring provinces.
Montreal Activates Storm Preparedness Plan
The City of Montreal says it is finalizing its operational plan to respond to the storm.
Municipal crews may be required to manage icy streets, monitor potential flooding in low-lying areas and respond to fallen trees or debris.
Hydro-Québec has not yet detailed its preparation measures. The utility says it is waiting for more precise forecasts from its own meteorologists before commenting publicly on potential impacts to the power grid.
Possible Flooding and Lingering Ice
While freezing rain is expected to dominate the storm, some areas could see regular rainfall instead, which may create localized flooding in certain communities.
Following the storm, temperatures are forecast to remain near the freezing mark through early Thursday before dropping sharply to around –12°C by Thursday night. Flurries may follow later in the week.
The colder temperatures could cause any remaining moisture to freeze, prolonging hazardous conditions on sidewalks and roads.
Environment Canada warns that icy surfaces may increase the risk of slips and injuries, and that extended power outages remain possible if ice accumulation becomes severe.
Residents are being advised to monitor local forecasts and consider postponing non-essential travel until conditions improve.
Conclusion
As southern Quebec prepares for a potentially prolonged freezing rain event, officials are urging residents to remain cautious and limit travel where possible. With the possibility of widespread ice accumulation, transportation disruptions and power outages, the midweek storm could have significant impacts across several major population centres, including Montreal and Quebec City.
