Canada: Adverse winter weather forecast across western regions through at least March 3 /update 2

Adverse winter weather is forecast over parts of western Canada through at least March 3. Snow and strong winds are likely across southern Alberta, most of Saskatchewan, and most of Manitoba through at least March 3, with the heaviest snow over southwestern Alberta through early March 1, across parts of northern and central Saskatchewan through the afternoon of March 1, and across northern Manitoba through March 1. Hazardous travel conditions are likely due to slippery roads and reduced visibility.

As of late Feb. 29, Environment Canada has issued the following warnings:

• Red snowfall warnings (the highest level on a three-tier scale): Parts of southwestern Alberta, northern Manitoba, and northern and central Saskatchewan.

• Grey special weather statements: the rest of the affected area from southeastern Alberta eastwards across central and southern Saskatchewan into central and southern Manitoba.

Officials could update and extend the coverage of weather alerts over the coming hours.

Snow accumulations are likely across the parts of 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 could lead to periods of blowing and drifting snow. Blizzard conditions are possible. Sporadic power outages may occur throughout the affected area.

The inclement weather will likely cause widespread ground and air transport disruptions across the affected areas. Traffic and commercial trucking delays are probable along regional highways. Dangerous and challenging driving conditions are likely, especially on secondary and rural roads, as maintenance crews prioritize clearing major routes. Authorities will probably close stretches of highways if driving conditions become too hazardous. Gusty winds will threaten to topple high-profile vehicles throughout the affected areas. As a precaution, mountain passes and tunnels will likely be closed during periods of intense snowfall. The disruptive weather will probably cause delays and cancellations at airports in the affected regions. Heavy, wet snow and strong winds could bring down power lines and trees with foliage.
