Canada: Adverse winter weather forecast across west-central regions through at least Dec. 3

Adverse winter weather is forecast over parts of west-central Canada through at least Dec. 3. A band of freezing rain is expected to stretch across north-central Alberta and into western Saskatchewan, with heavy snowfall forecast in eastern Saskatchewan and western Manitoba. Both forms of precipitation are expected to taper off during the morning Dec. 3. Snowfall accumulations of up to 10-15 cm (20 inches) are expected across parts of the affected area. Hazardous travel conditions are likely across the affected region due to slippery roads and reduced visibility caused by blowing snow.

As of Dec. 2, Environment Canada has issued red freezing rain warnings (the highest level on a three-tier scale) across parts of north-central Alberta and western Saskatchewan and red snowfall warnings are in place for parts of eastern Saskatchewan and western Manitoba. Officials could update and extend the coverage of weather alerts over the coming hours.

Lesser snow accumulations 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. 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 especially likely 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.
