Canada: Adverse winter weather forecast across parts of central British Columbia through at least Nov. 29

Adverse winter weather is forecast over parts of central British Columbia through at least Nov. 29. A low-pressure system over the Gulf of Alaska is expected to spread heavy snowfall across the region Nov. 27-29. Snowfall accumulations of 20-50 cm (8-20 inches) are possible in affected areas. Environment Canada has issued red winter storm warnings (the highest level on a three-tier scale) across the affected area, as well as heavy snowfall warnings for some highway passes in the region. 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 likely 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.
