Québec : Forte tempête de neige et refroidissement glacial attendus ce week-end

A significant winter weather system is forecast to sweep across the province, bringing a potentially dangerous combination of heavy snowfall, strong winds, and a rapid temperature drop. Residents should prepare for challenging conditions, particularly during travel, as the storm progresses from west to east.

Storm Timeline and Regional Impacts

Northwestern Quebec First in the Path

The initial impact of the storm is expected Friday afternoon in the Abitibi-Témiscamingue region. Specifically, reduced visibility due to heavy snowfall is possible between 12 PM and 2 PM near Rouyn-Noranda, and between 2 PM and 4 PM around Val-d’Or.

Did You Know? The combination of strong winds and falling temperatures is a key factor in the formation of ground blizzards.

Expanding Eastward: Outaouais and the Laurentians

As the system moves eastward, the Outaouais and the Hautes-Laurentides regions will experience deteriorating conditions Friday evening. Travelers on Autoroute 15 and Route 117, particularly those heading north, should anticipate difficult driving conditions.

Southern Quebec: Overnight and Saturday Impacts

The greater Montreal area and the Estrie region are expected to be affected later, with potential for heavy snowfall overnight Friday into Saturday morning. Snowfall is anticipated to continue in the Estrie region into Saturday afternoon.

Potential Snow Accumulation and Temperature Drop

Total snowfall accumulation is generally forecast to be between 5 and 10 centimeters. Adding to the hazardous conditions, temperatures will plummet approximately 10°C in a matter of hours, exacerbating the risk of blowing snow and reduced visibility.

Expert Insight: The rapid temperature drop combined with strong winds creates a scenario where even moderate snowfall can lead to significantly reduced visibility and hazardous travel conditions. Drivers should exercise extreme caution and consider delaying non-essential travel.

Looking Ahead

Should this system track as currently predicted, conditions could remain challenging throughout the weekend, with lingering cold air following the storm’s passage. Travel disruptions will continue beyond Saturday, depending on the extent of snowfall and the effectiveness of road clearing operations. If conditions worsen, further advisories or warnings may be issued.
