Canada: Adverse winter weather conditions forecast over parts of central regions through at least Nov. 7

Adverse winter weather conditions are forecast across parts of northern Ontario, southern Quebec, far southern Manitoba, and central Saskatchewan provinces through at least Nov. 7. Hazardous driving conditions are likely across the affected areas due to icy roads and reduced visibility caused by blowing snow. Heavy rainfall may result in floods and flash floods.

As of late Nov. 5, Environment Canada has issued red snowfall warnings across parts of northern Ontario, southern Quebec, far southern Manitoba, and central Saskatchewan provinces; up to 20 cm (8 inches) of snow is forecast. The snowfall is forecast to ease over far southern Manitoba and northwestern Ontario late Nov. 5, central Saskatchewan early Nov. 6, central Ontario the afternoon of Nov. 6, northeastern Ontario late Nov. 6, and southern Quebec Nov. 7. Red freezing rain warnings are in place for Dryden, Ignace, Kenora, and Nestor Falls in Ontario. 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. 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 also likely 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 precautionary measure 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.
