Adverse winter weather is forecast over parts of northern Ontario through at least early March 27. As of late March 24, Environment Canada has issued the following warnings:

• Red snowfall warnings (the highest level on a three-tier scale): Atikokan, Dryden, Fort Frances, Ignace, Rainy Lake, Shebandowan, and Quetico Park. Snowfall of 20-35 cm (8-14 inches) is forecast through early March 27. The heaviest snow is likely March 25-26.

• Red winter storm warnings: City of Thunder Bay, Geraldton, Hornepayne, Manitouwadge, Marathon, Nipigon, Lake Nipigon, Raith, Superior North, Superior West, Upsala, and Wabakimi. Snowfall of 25-45 cm (10-18 inches) is forecast through early March 27. The heaviest snow is likely March 25-26.

• Yellow winter storm warnings: Attawapiskat, Fort Hope, and Webequie.

• Grey special weather statements for poor visibility and blowing snow: the rest of the affected area.

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.

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, authorities will likely close mountain passes and tunnels 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. Sporadic power outages may occur throughout the affected area.
