Canada: Adverse winter weather forecast over parts of central regions through at least Oct. 27

Adverse winter weather is forecast across parts of northern Ontario and far southeastern Manitoba provinces through at least Oct. 27. Hazardous driving conditions are likely across the affected area due to icy roads and reduced visibility caused by blowing snow. Heavy rainfall may result in floods and flash floods.

As of late Oct. 26, Environment Canada has issued red snowfall warnings across most of northern Ontario and far southeastern Manitoba provinces; 10-20 cm (4-8 inches) of snow is forecast. Red freezing rain warnings are in place for parts of northern Ontario, north of Lake Superior; freezing rain is forecast through early Oct. 27 at higher elevations. Precipitation should remain as rain for lower elevation areas near Lake Superior. Grey special weather statements for freezing rain, snow, and rain are in place across the rest of the affected area. Officials will likely issue new alerts or update/rescind existing advisories as weather conditions change over the coming days.

Snow accumulations are likely across the affected area. Lesser snowfall totals are possible where sleet and freezing rain mix with snow. In addition to the heavy snow, strong wind gusts will probably lead to periods of blowing and drifting snow. Blizzard conditions are possible. Sporadic power outages are possible throughout the affected area.

The inclement weather will likely cause widespread ground and air transport disruptions across the affected area. Traffic and commercial trucking delays are possible along regional highways. Dangerous and challenging driving conditions are also probable on secondary and rural roads in the affected provinces as maintenance crews prioritize clearing major routes. Authorities will likely close stretches of highways if driving conditions become too hazardous. Gusty winds will threaten to topple high-profile vehicles throughout the affected area. Mountain passes and tunnels will probably be closed as a precautionary measure during periods of intense snowfall. The disruptive weather will likely cause delays and cancellations at airports in the affected region. Heavy, wet snow and strong winds could bring down power lines and trees with foliage.
