Canada: Adverse winter weather conditions forecast over parts of southern Ontario Province through at least Nov. 8

Adverse winter weather conditions are forecast across parts of southern Ontario Province through at least Nov. 8. A low-pressure system is forecast to bring snow, rain, and freezing rain to the region. Precipitation could begin as snow the afternoon of Nov. 8 before quickly changing to freezing rain and slowly changing to rain through the evening. Ice accumulation will likely be variable as the ground is still relatively warm. Surfaces, such as roads, streets, sidewalks, and parking lots, may become icy and slippery. Ice accumulation could break tree branches. Hazardous driving conditions are likely across the affected areas due to icy roads and reduced visibility caused by blowing snow.

As of late Nov. 7, Environment Canada has issued red freezing rain warnings across Barrie, Bruce, Dufferin, Gray, Innisfil, Halton, Huron, Midland, Orillia, Peel, Perth, Waterloo, and Wellington. Ice accumulations of 0.2-0.5 cm (0.08-0.2 inches) are forecast across the affected areas. Grey special weather statements for freezing rain are in place across the rest of the affected area. 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 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 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.
