Quebec Faces Major Winter Storm: Freezing Rain, Heavy Snow, and Flooding

This weekend, a significant weather system originating from the southern United States is set to impact several regions of Quebec, bringing with it a potent mix of freezing rain, heavy snow, and the potential for significant flooding. Environment Canada has issued special weather bulletins for various areas, urging residents to prepare for challenging conditions.

Timing and Intensity of the Storm

The storm is expected to arrive in western Quebec, including areas near Val-d'Or, on Friday, bringing initial bouts of rain or freezing drizzle. However, The main impact for the Saint Lawrence Valley will be felt from Saturday evening through Sunday morning. This period will feature freezing rain, potentially accumulating to 2 millimeters of ice. Precipitation intensity will vary, with periods of lulls, but freezing rain will persist primarily overnight Saturday into Sunday. This will be followed by intermittent freezing drizzle on Sunday.

Impact on Roads and Infrastructure

The accumulation of ice, even in relatively small amounts, poses a significant risk to road safety. Surfaces such as roads, sidewalks, and parking lots could quickly become icy and slippery. The Sûreté du Québec (SQ) spokesperson emphasizes the importance of adjusting driving to road conditions, reducing speed on slippery roads, monitoring the taillights of preceding vehicles, maintaining a safe distance, and above all, adapting driving to current conditions. Failure to do so could lead to infractions under the Highway Safety Code. The SQ urges drivers to exercise extreme caution throughout the duration of the ice storm, which could persist into Sunday morning. Routes 113 and 117 around Val d'Or, along with routes 15, 40, and 50 later in the day, will need extra attention.

The Transition to Rain and Flooding

By Sunday evening, temperatures are expected to rise above freezing, transitioning the precipitation from freezing rain to rain. This will last into Monday evening, potentially accelerating snowmelt and making roadways heavier with water and slush. The significant rainfall, potentially reaching 20 to 30 millimeters, with up to 50 millimeters in some areas along the Saint Lawrence River and higher elevations to the north, warrants concerns about localized flooding. River levels will need monitoring into the early part of next week.

Smog Alert and Air Quality Concerns

Adding to the complexity of the weekend weather event, Environment Canada has also issued a smog warning for several areas of southern Quebec. High concentrations of pollutants are anticipated, leading to poor air quality, especially in areas with higher emission levels. This is linked to an anticyclone that has kept air stagnant over Quebec for the past two days, trapping pollutants near the surface. Wood-burning heating is identified as a major contributor to this smog in the province. Those with respiratory and cardiac issues, especially children, are advised to limit strenuous outdoor activity during this period.

A Look Ahead

While Quebec will likely experience a break in precipitation on New Year's Eve, another weather system is expected to move into the southern part of the province shortly after. This ongoing active weather pattern highlights the importance of monitoring forecasts and alerts from Environment Canada in the coming days. The unpredictable nature of the storm’s evolution requires constant vigilance from weather agencies and individuals alike. Staying informed and adapting to changing conditions are critical steps in ensuring a safe passage through this complex weather event. Remember to check road conditions regularly and heed all weather warnings. Prioritize safety above all else. This isn't just about dealing with the weather; it's about protecting the health and safety of everyone.
