Canada: Adverse winter weather forecast over southwestern regions through at least Feb. 21
Adverse winter weather forecast across parts of southwestern Canada through at least Feb. 21. Hazardous travel conditions likely.
Event
Adverse winter weather is forecast across parts of southwestern Canada through at least Feb. 21. Heavy snowfall, strong winds, and cold temperatures are expected across parts of central and southern British Columbia and southwestern Alberta. Snowfall accumulations of 10-50 cm (4-20 inches) are forecast across the affected areas and winds gusting up to 100 kph (62 mph) are possible in parts of southwestern British Columbia. Hazardous driving conditions are likely due to icy roads and reduced visibility caused by blowing snow.
As of early Feb. 20, Environment Canada has issued the following weather warnings across the affected area:
Red snowfall warnings: Parts of central British Columbia and southwestern Alberta.
Red winter storm warnings: Parts of southern British Columbia and far southwestern Alberta.
Red strong wind warnings: Parts of southwestern British Columbia.
Special weather statement for strong winds: Parts of southwestern British Columbia.
Air quality alert: Parts of southern British Columbia.
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.
