Potentially 'critical' freezing rain event threatens Quebec
Tracking a potentially significant ice storm expected to impact Quebec mid-week
An incoming ice storm is expected to impact parts of southern Quebec mid-week, following mild temperatures to start the work week. Prolonged freezing rain could result in damage and multi-day power outages.
Environment and Climate Change Canada (ECCC) has issued special weather statements, warning of "a potentially critical freezing rain situation."

Temperatures soar ahead of the storm
Southern Quebec begins the week with mild weather as temperatures climb into the mid-teens on Monday. Montreal could hit its first 15°C of the year. A mix of sun and cloud is forecast in the south, with a wintry mix and snowfall over northern regions.
Tuesday will see above-seasonal temperatures continue as clouds increase throughout the day ahead of a major 24+ hour storm system. Moisture streaming in from the southern U.S. will arrive Tuesday night, leading to widespread impacts.
Wednesday: Significant ice storm possible
Freezing rain and ice pellets are expected across southern Quebec on Wednesday, including areas like Montreal, Gatineau, and the Eastern Townships.
The precipitation will intensify through the early hours of Wednesday and persist throughout the day.
A shift in warmer air could alter the freezing rain’s location, with some regions potentially seeing more rain than ice depending on the storm track.
Central and eastern Quebec regions including Gaspé and the Lower North Shore are forecast to see significant snowfall. As the system moves east overnight into Thursday, colder air will draw south, shifting any remaining rain or freezing rain into a wintry mix or snow.
Snowfall amounts of 5-20+ cm are expected in the Outaouais, Laurentians, Quebec City region, and Gaspé, with 15-30 mm of rain anticipated for parts of the Eastern Townships.
Forecasts indicate 5-20+ mm of freezing rain, with locally higher amounts exceeding 30+ mm in some areas. Ice accumulation will vary based on wind speeds, precipitation intensity, and surface conditions.
Prolonged freezing rain may result in risks such as multi-day power outages, slippery untreated surfaces, and potential tree damage from accumulating ice.
Travel disruptions, including flight delays and cancellations, are possible in Montreal.
Cold conditions in the days ahead could complicate and prolong the full restoration of services.
"Consider delaying or cancelling any non-essential travel," adds ECCC.
