Canada: Adverse winter weather forecast over western regions through at least March 4
Adverse winter weather forecast across western Canada through at least March 4. Hazardous travel conditions likely.
Event
Heavy snowfall is forecast across parts of western Canada through at least March 4. As of late March 3, authorities have issued red snowfall warnings across southeastern Alberta, southwestern Manitoba, and southern Saskatchewan provinces. 10-20 cm (4-8 inches) of snow is forecast by late March 4. 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.
Where precipitation falls as rain, flash, and areal flooding is possible. Such flooding is possible in low-lying communities near watercourses and other large bodies of water and in urban areas with easily overwhelmed stormwater drainage systems. Sites located downstream of large reservoirs may be subject to flash flooding after relatively short periods of intense rainfall.
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.
