Canada: Adverse winter weather forecast over southern and southeastern regions through at least Jan. 5
Adverse winter weather forecast across parts of southern and southeastern Canada through Jan. 5. Hazardous travel conditions likely.
Event
A mix of wintry precipitation, including snow, freezing rain, ice pellets, and rainfall, is forecast across parts of southern and southeastern Canada through at least Jan. 5. Hazardous travel conditions are likely due to icy roads and reduced visibility caused by fog and blowing snow. Flooding is possible in areas where precipitation predominantly falls as rain.
As of early Jan. 4, Environment Canada has issued red snowfall and freezing rain warnings across parts of southern Ontario, as well as red smog warnings for parts of southern Quebec. Fog advisories, weather advisories, and special weather statements for mixed precipitation are in place across much of southern Ontario and Quebec, as well as across Nova Scotia. Authorities will likely issue new alerts or update/rescind existing advisories as the winter storm transits the region over the coming days.
Snow and ice accumulations are possible across the affected area. Lesser snowfall totals are possible where sleet and freezing rain mix with snow. Flooding is possible in low-lying areas that experience periods of heavy rainfall. 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 likely 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. 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.
