A significant weather system is set to impact eastern Ontario and southern Quebec, with Environment Canada issuing warnings for freezing rain across numerous cities, including Ottawa, Gatineau, Montreal, and Quebec City. Over the next 24 hours, meteorologists predict ice accumulation ranging from 10 to 40 millimetres, raising concerns about infrastructure damage and hazardous travel conditions.
Ice Accumulation and Its Impacts
Global News meteorologist Ross Hull highlighted the potential dangers of freezing rain, stating, “Even at 10 mm, you’re looking at an impact on infrastructure. So power outages, tree limbs falling and those types of things.” The forecast indicates that while Ottawa and Montreal will experience freezing rain, regions further north may receive greater ice accumulation. Hull cautioned residents of northern areas, saying, “It’s something certainly to be on the lookout for farther north of Montreal.”
As the storm progresses, the Saguenay-Lac-Saint-Jean region is expected to face adverse winter conditions, including strong winds, snow, and ice pellets. Accumulation in this area could reach between 30 and 40 centimetres by Thursday evening.
Variability and Travel Disruptions
Hull noted the variability of the storm, emphasising that temperatures and precipitation levels may differ across locations. “If there are power outages, they’re going to be dealing with cold conditions, and the ice isn’t going to melt,” he explained. Residents should remain vigilant as the freezing rain could lead to treacherous conditions on roads and walkways.
Travel is likely to be affected significantly, with aircraft requiring de-icing and road treatments becoming essential. As conditions worsen, Hull advised people to stay informed and prepare adequately.
Rainfall and Flood Risks in Southern Ontario
In addition to freezing rain, southern Ontario faces a yellow weather warning for rainfall, with forecasts of 20 to 40 millimetres expected. Environment Canada has cautioned that the already saturated or frozen ground will struggle to absorb this additional water, increasing the risk of flooding. The Toronto and Region Conservation Authority has urged residents to avoid rivers, shorelines, and nearby trails until Thursday evening and to be watchful for pooling water on roads and in low-lying areas.
The Potential for More Snow
Despite the current storm, winter is not yet over for southern Ontario. Hull noted that a clipper system is approaching, which may bring an additional two to five centimetres of snow to certain areas. “We’re not done with the snow, which I know a lot of people are probably not happy about,” he remarked, indicating that the winter weather will likely continue to disrupt daily life.
Why it Matters
The impending weather system poses significant risks to public safety and infrastructure across eastern Ontario and southern Quebec. The combination of freezing rain, snowfall, and potential flooding can lead to dangerous travel conditions and power outages, making it crucial for residents to stay informed and prepared. As communities brace for the impact of this storm, the resilience and readiness of both individuals and local authorities will be tested in the face of challenging winter weather.
