Canada: Adverse winter weather forecast over parts of British Columbia through at least Nov. 3

Adverse winter weather is forecast across parts of southern and south-central British Columbia through at least Nov. 3. A mix of heavy snowfall and freezing rain are forecast across the affected region, with widespread snowfall accumulations of 5-10 cm (2-4 inches) possible across south-central regions and freezing rain more likely in southern areas. Hazardous driving conditions are likely across the affected area due to icy roads and reduced visibility caused by blowing snow.

As of Nov. 1, Environment Canada has issued red freezing rain warnings across 100 Mile, Nicola, Similkameen, and South Thompson forecast districts. Grey special weather statements for heavy snowfall and freezing rain are in place across the rest of the affected area. Warnings and special weather statements are also in place for several highway passes in the affected area due to hazardous travel conditions. Officials will likely issue new alerts or update/rescind existing advisories as weather conditions change over the coming days.

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 probably lead to periods of blowing and drifting snow. Sporadic power outages are possible throughout the affected area.

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 probable 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. Mountain passes and tunnels could be closed as a precautionary measure during periods of intense snowfall. The disruptive weather will likely cause some delays and cancellations at airports in the affected region. Heavy wet snow and strong winds could bring down power lines and trees with foliage.
