Canada: Adverse winter weather forecast parts of eastern and southeastern Ontario and southwestern Quebec Nov. 26

Adverse winter weather is forecast over parts of eastern and southeastern Ontario and southwestern Quebec Nov. 26. A mix of heavy snowfall and freezing rain is expected across the region, with snowfall accumulations of 10-30 cm (4-12 inches) possible in parts of eastern Ontario and ice accumulations of 0.1-0.4 cm (0.04-0.15 inches) possible in parts of southeastern Ontario and southwestern Quebec. As of early Nov. 26, Environment Canada has issued red freezing rain warnings (the highest level on a three-tier scale) and grey special weather statements for freezing rain across parts of southeastern Ontario and southwestern Quebec. A yellow snow squall watch is in place for Salut St. Marie and surrounding areas of Ontario and a grey weather advisory for heavy snowfall is in place across parts of eastern Ontario. Officials could update and extend the coverage of weather alerts over the coming hours.

The inclement weather will likely cause ground and air transport disruptions across the affected areas. Traffic and commercial trucking delays are possible along regional highways. Dangerous and challenging driving conditions are especially likely on secondary and rural roads as maintenance crews prioritize clearing major routes. Authorities will probably close stretches of highways if driving conditions become too hazardous. As a precaution, mountain passes and tunnels may be closed during periods of intense snowfall. The disruptive weather may 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.
