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.
