Canada: Winter storm to bring adverse weather to parts of southern Ontario and Quebec through at least early Feb. 24
Adverse winter weather forecast across parts of southern Canada through at least early Feb. 24. Hazardous travel conditions likely.
Event
A winter storm system is forecast to bring adverse winter weather to parts of southeastern Ontario and southwestern Quebec through at least early Feb. 24. The storm will bring heavy snowfall, freezing rain, and strong winds across parts of the affected area. Snowfall accumulations of 5-25 cm (2-10 inches) are forecast across the region, as well as dangerous ice accretions. Hazardous driving conditions are likely due to icy roads and reduced visibility caused by blowing snow.
As of early Feb. 22, Environment Canada has issued red snowfall, winter storm, and freezing rain across affected areas of southern Ontario and far western parts of affected areas of southern Quebec. Special weather statements regarding the storm have been issued for the remaining areas of southern Quebec. Officials will likely issue new alerts or update/rescind existing advisories as weather conditions change over the coming days.
Snow accumulations are likely across the affected area. Lesser snowfall totals are possible where sleet and freezing rain mix with snow. In addition to the heavy snow, strong wind gusts will probably lead to periods of blowing and drifting snow. Blizzard conditions are possible. Sporadic power outages are possible throughout the affected area.
The inclement weather will likely cause widespread ground and air transport disruptions across the affected area. Traffic and commercial trucking delays are possible along regional highways. Dangerous and challenging driving conditions are also probable on secondary and rural roads in the affected provinces as maintenance crews prioritize clearing major routes. Authorities could close stretches of highway if driving conditions become too hazardous. Gusty winds may threaten to topple high-profile vehicles throughout the affected area. Heavy wet snow and strong winds could bring down power lines and trees with foliage. Flight delays and cancellations are likely due to ground stops and deicing operations at airports across the affected region.
Advice
Monitor local media for updated weather information. Verify road conditions before driving in areas where heavy snowfall is forecast. Allow extra time to reach destinations in these areas and carry an emergency kit and warm clothes if driving is necessary, especially on secondary or rural routes that could become impassable. If routing shipments by truck through the affected area, plan accordingly for delivery delays. Confirm flights. Charge battery-powered devices in the case of prolonged electricity outages.
