Canada: Storm system to bring heavy snowfall, strong winds, and ice to western provinces through at least Jan. 14
Rounds of snow, ice, and strong winds forecast across western provinces of Canada through at least Jan. 14. Disruptions possible.
Event
Heavy snowfall, strong winds, and ice are forecast across portions of western Canada through at least Jan. 14. The affected area includes southern British Columbia, southern and central Alberta, far western Manitoba, and southern and central Saskatchewan. As of early Jan. 13, Environment Canada has issued snowfall, winter storm, strong winds, and freezing rain warnings for southern and central Alberta. Additionally, snowfall and strong wind warnings are in effect across southern British Columbia. Winter storm watches are in place in west-central Manitoba, and winter storm, freezing rain, and strong wind warnings are in effect across southern 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
The latest forecast guidance indicates that accumulations of 10-15 cm (4-6 inches) of snowfall are expected across the affected area. However, lower snowfall totals are possible where sleet and freezing rain mix with snow. In addition to the heavy snow, strong wind gusts are likely to 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 through at least Jan. 14. Traffic and commercial trucking delays are possible along regional highways, including the Trans-Canada Highway. Difficult and potentially dangerous driving conditions are also likely on secondary and rural roadways in the affected states 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. As of early Jan. 13, over 100,000 people are without power in British Columbia as a result of the system.
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. Plan accordingly for delivery delays if routing shipments by truck through the affected area through at least Jan. 14. Confirm flights. Charge battery-powered devices in the case of prolonged electricity outages.
