Canada: Adverse winter weather forecast over western and central regions through at least Nov. 3
Adverse winter weather forecast across parts of western and central Canada through at least Nov. 3. Hazardous travel conditions likely.
Event
A low pressure system is forecast to bring adverse winter weather across parts of western and central Canada through at least Nov. 3. Heavy snowfall, freezing rain, and dropping temperatures are forecast across parts of the Prairies as the system moves west to east over the region Nov. 2-3. Snowfall accumulations of 10-40 cm (4-8 inches) are likely across parts of Alberta and Saskatchewan, with the heaviest accumulations likely over higher ground. Heavy snow and freezing rain will likely lead to hazardous driving conditions due to reduced visibility and icy roads.
As of early Nov. 2, authorities have issued red snowfall warnings across parts of far southeastern British Columbia, southern Alberta, and central Saskatchewan provinces. Freezing rain warnings have been issued across parts of central Manitoba and central Saskatchewan and special weather statements regarding freezing rain and heavy snowfall have been issued for parts of north-central Manitoba, far northwestern Ontario, and southwestern and central Saskatchewan. Authorities will likely issue new alerts or update/rescind existing advisories as the winter storm transits the region over the coming days.
Hazardous Conditions
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 likely lead to periods of blowing and drifting snow. Blizzard conditions are possible. Sporadic power outages are possible throughout the affected area.
Transport and Utilities
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. 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 regional airports.
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.
