Canada: Adverse winter weather forecast across parts of west-central Alberta through at least Dec. 2

Adverse winter weather is forecast over parts of west-central Alberta through at least Dec. 2. A long period of snowfall, with total snowfall amounts of 20-30 cm (8-12 inches), is forecast through Dec. 2. Snowfall amounts may be as high as 50 cm (20 inches) in some areas. Light snow is ongoing but will become heavier late Nov. 29-29, with total snowfall amounts of 10-20 cm (4-8 inches) by the evening of Nov. 29. The snow will become very light late Nov. 29 but is likely to intensify again Nov. 30 before easing Dec. 2.

Environment Canada has issued red snowfall warnings (the highest level on a three-tier scale) across the affected area. Hazardous travel conditions are likely across the affected area due to slippery roads and reduced visibility caused by blowing snow. Officials could update and possibly extend the coverage of weather alerts over the coming hours and days.

In addition to the wintry precipitation, strong wind gusts could lead to periods of blowing and drifting snow. Sporadic power outages are possible throughout the affected area.

The inclement weather will likely cause ground and air transport disruptions across the affected areas. Traffic and commercial trucking delays are possible 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. As a precaution, mountain passes and tunnels may be closed during periods of intense snowfall. The disruptive weather may 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.
