A significant weather system is poised to hit eastern Ontario and southern Quebec, bringing with it the potential for hazardous freezing rain. Environment Canada has issued an orange alert, forecasting an ice accumulation of between 10 to 40 millimetres over the next 24 hours, affecting major urban centres such as Ottawa, Gatineau, Montreal, and Quebec City.
Ice Accumulation and Infrastructure Risks
Meteorologist Ross Hull from Global News has emphasised that even minimal ice accumulation can lead to serious infrastructure challenges. “If that does happen, then you’re looking at an impact on infrastructure. So power outages, tree limbs falling and those types of things,” Hull explained. Areas such as Ottawa and Montreal are expected to see freezing rain, but regions further north may experience even greater ice accumulation. Hull cautioned, “It’s something certainly to be on the lookout farther north of Montreal.”
Winter Storm Conditions in Saguenay-Lac-Saint-Jean
In addition to the freezing rain warnings, the Saguenay-Lac-Saint-Jean area is bracing for a winter storm, featuring strong winds, snow, and ice pellets. Forecasts predict snowfall accumulations between 30 to 40 centimetres from Wednesday through Thursday evening. Hull noted that weather conditions could vary significantly across different locations, urging residents to remain vigilant and prepared as temperatures fluctuate.
Travel Disruptions and Flood Risks
Travelers should also be prepared for disruptions due to the weather. Hull highlighted the necessity for planes to de-ice and for road crews to treat highways and walkways, which could significantly affect travel plans. He also raised concerns about flooding in southern Ontario, where a yellow rainfall warning is in effect. Up to 40 millimetres of rain is anticipated, which, combined with already saturated or frozen ground, poses a risk of flooding in low-lying areas.
The Toronto and Region Conservation Authority has advised residents to avoid rivers, shorelines, and nearby trails until Thursday evening due to these heightened risks. They also cautioned drivers to be aware of potential ponding on roads and underpasses.
Continued Winter Weather Ahead
Those hoping for a swift end to winter may be disappointed. Hull has indicated that a clipper system is on its way to Ontario, which could bring an additional 2 to 5 centimetres of snow to southern regions. “So we’re not done with the snow, which I know a lot of people are probably not happy about,” he remarked.
Why it Matters
The impending winter weather poses serious risks not only to infrastructure and travel but also to public safety in eastern Ontario and southern Quebec. With freezing rain and potential flooding on the horizon, residents are urged to stay informed and take necessary precautions. As climate patterns continue to evolve, understanding and preparing for such extreme weather events has become increasingly vital for communities across Canada.
