A powerful late-winter system is sweeping across southern Québec, bringing heavy freezing rain and winter storm conditions that could cause widespread power outages, dangerous travel and property damage.
Environment Canada has issued freezing rain and winter storm warnings for much of the region, forecasting significant ice accumulation between Ottawa, Gatineau, Montreal and Québec City. Meteorologists say between 20 and 40 millimetres of freezing rain could fall over a 24-hour period, creating hazardous conditions across major transportation corridors.
The federal weather agency warned that the heavy buildup of ice could weigh down power lines and tree branches, potentially triggering widespread outages, disrupting travel and damaging property.
In northern parts of the province, including the Saguenay–Lac‑Saint‑Jean region, the system is expected to bring full winter storm conditions. Strong winds combined with heavy snow and ice pellets could produce accumulations of 30 to 40 centimetres through Wednesday and into Thursday evening.
Utility provider Hydro‑Québec reported that nearly 9,000 addresses were already without electricity as of 3:30 a.m. Wednesday, with officials warning that the number could rise as ice continues to accumulate on infrastructure.
Authorities are urging residents to limit travel where possible and prepare for potential power disruptions as the storm moves through the province.
