Canada: Adverse winter weather forecast across parts of Newfoundland and Labrador Province through at least Dec. 8

A winter storm is forecast to bring heavy snowfall and strong winds across parts of Newfoundland and Labrador Province through at least Dec. 8. Environment Canada has issued the following warnings:

• Red winter storm warnings (the highest level on a three-tier scale): From Natuashish to Makkovik in northern Labrador and Corner Brook, Gros Morne, Parson's Pond, and Hawkes Bay in Newfoundland Island. Snowfall of up to 40 cm (16 inches) is forecast, with the highest snowfall in northern Labrador. Strong winds of up to 80 kph (50 mph) are likely.

• Red wind warnings: Northwestern Newfoundland Island.

• Grey blowing snow advisories: Most of the rest of the affected area.

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

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 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 likely close stretches of highways if driving conditions become too hazardous. Gusty winds will threaten to topple high-profile vehicles throughout the affected areas. Mountain passes and tunnels will probably be closed as a precaution during periods of intense snowfall. The disruptive weather will likely 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.
