Canada: Adverse winter weather forecast across parts of southwestern Manitoba and eastern and southeastern Saskatchewan through at least Nov. 20

Adverse winter weather is forecast over parts of southwestern Manitoba and eastern and southeastern Saskatchewan through at least Nov. 20. A low-pressure system is expected to initially bring rainfall and freezing rain to the region from late Nov. 18 before precipitation transitions to heavy snowfall. Strong winds are also likely over the coming days. Snowfall accumulations of 15-30 cm (6-12 inches) are probable in places, with higher accumulations possible in higher elevations, as well as winds gusting up to around 80 kph (50 mph). Hazardous travel conditions are likely across the affected area due to slippery roads and reduced visibility caused by blowing snow.

As of early Nov. 18, Environment Canada has issued red snowfall warnings (the highest level on a three-tier scale) across parts of eastern Saskatchewan and yellow winter storm watches across the rest of the affected area. Officials could update and extend the coverage of weather alerts over the coming hours and days.

In addition to the wintry precipitation, strong wind gusts could lead to periods of blowing and drifting snow. Sporadic power outages are likely throughout the affected area.

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.
