Quebec Braces for Major Ice Storm, Potential Power Outages
Quebec is preparing for a significant ice storm expected to hit Wednesday, potentially impacting millions. Forecasters predict between 20 to 30 mm of freezing rain, with up to 40 mm in some areas, and 20 to 40 cm of snow further north. This represents the most substantial ice storm threat in three years, recalling the devastating storm of April 2023 that left over a million homes without power.
The “Colorado Low” System
Meteorologists are tracking a “Colorado Low,” a typical winter and spring weather system that draws moisture from the southern United States. This system brought warmer temperatures to Quebec at the finish of last week, and its arrival will now bring freezing rain and snow. The system is described as “quite robust” and has been monitored for over a week.
Potential Impacts: Travel, Power, and Safety
Environment Canada has issued warnings, describing the situation as “potentially critical.” The freezing rain could last for 24 hours, potentially “paralyzing certain services.” The hardest-hit regions are expected to include the greater Montreal area, Montérégie, Lanaudière, Laurentides, and Outaouais, with the system moving towards Mauricie, Centre-du-Québec, and the Quebec City region.
Travel disruptions are highly likely, with potential delays and cancellations. Icy surfaces will increase the risk of slips, trips, and falls. Northern regions like Abitibi-Témiscamingue, Saguenay–Lac-Saint-Jean, and Gaspésie are bracing for a major winter storm with strong winds up to 70 km/h, leading to blowing snow and road closures.
Lessons from 2023 and Preparations
This event is comparable to the ice storm of April 2023, which saw 30 mm of freezing rain impact southwestern Quebec, causing widespread power outages. While a repeat of the 1998 ice storm is not anticipated, officials are taking precautions. Recent storms in November have potentially weakened some tree branches, reducing the risk of widespread damage. The lack of strong winds on Wednesday may also help mitigate power outages.
The City of Montreal is preparing for potential overflows in the municipal network. Around 1,000 employees, along with firefighters and police, will be deployed to clear drains and prevent ice accumulation. The Montreal transit authority (STM) and the Réseau express métropolitain (REM) are also preparing for potential disruptions, with the REM considering reduced frequency to prioritize trains equipped with ice-clearing equipment.
What Residents Should Do
Authorities are urging residents to exercise caution and avoid non-essential travel. Coordination between the city, fire department, transit authorities, and Hydro-Québec is underway to manage the situation effectively.
