Canada: Adverse winter weather forecast across central Manitoba and central Saskatchewan through at least April 19

Adverse winter weather is forecast over central Manitoba and central Saskatchewan through at least April 19. Hazardous travel conditions are likely due to slippery roads and reduced visibility caused by blowing snow.

As of late April 16, Environment Canada has issued red snowfall warnings (the highest level on a three-tier scale) across the affected area. In central Saskatchewan, snowfall totals of 15-30 cm (6-12 inches) are forecast, with the snow tapering off April 18. 20-30 cm (8-12 inches) of snow is likely over Thompson, Nelson House, South Indian Lake and Amisk Provincial Park, Split Lake, and York Landing in central Manitoba. The snow is forecast to ease late April 17 and continue as light snow April 18 before tapering off through April 19. Officials could update and extend the coverage of weather alerts over the coming hours.

Lesser snow accumulations 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 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. Gusty winds will threaten to topple high-profile vehicles throughout the affected areas. As a precaution, mountain passes and tunnels will likely be closed during periods of intense snowfall. The disruptive weather will probably 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.
