Canada: Adverse winter weather weather conditions forecast across southeastern regions through at least Dec. 24

Adverse winter weather conditions are forecast over parts of southeastern Canada through at least Dec. 24. A low-pressure system will bring heavy snowfall across the affected area. Hazardous travel conditions are likely across the region due to reduced visibility caused by blowing snow.

As of late Dec. 22, Environment Canada has issued the following warnings:

• Red snowfall warnings (the highest level on a three-tier scale): Bayfield Inlet, Baysville, Bracebridge, Coldwater, Dunchurch, Gravenhurst, Huntsville, Killbear Park, Lagoon City, Midland, Orillia, Orr Lake, Port Carling, Port Severn, Town of Parry Sound, Rosseau, and Washago in southern Ontario. Total snowfall amounts of 15-20 cm (6-8 inches) are forecast through late Dec. 23.

• Yellow snow squall watches: Western Cape Breton through the afternoon of Dec. 23.

• Grey special weather statements and weather advisories for snowfall: Across most of the rest of the affected area.

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

Snow accumulations are likely across the affected region, especially at higher elevations. Lesser accumulations are possible where sleet and freezing rain mix with the snow, and precipitation is less intense. In addition to the heavy snow, strong wind gusts will likely lead to periods of blowing and drifting snow in some areas. Sporadic power outages could occur throughout the affected region.

The winter weather will likely cause disruptions to ground and air transport across the region. Traffic and commercial trucking delays are probable along regional highways. Dangerous and challenging driving conditions are likely on secondary and rural roads in the affected states as maintenance crews prioritize clearing major routes. Authorities will probably close stretches of highways if driving conditions become too hazardous. Flight delays and cancellations are likely due to ground stops and deicing operations at regional airports.
