Event

Heavy snowfall, strong winds, freezing rain, extreme cold, and winter storm conditions are forecast across Upper Midwest and West North Central regions, US and central Canada through at least Feb. 12.

As of late Feb. 10, the US National Weather Service has issued blizzard warnings across far eastern North Dakota and northwestern Minnesota. Winter weather advisories are in place for parts of northeastern Michigan, northern Minnesota, western New York, eastern North Dakota, and northern Wisconsin.

The US Weather Prediction Center (WPC) has warned of the risk of heavy snow over the Great Lakes. More than 15 cm (6 inches) of snow is likely over the Upper Peninsula of Michigan the afternoon of Feb. 11 through early Feb. 12. Light snow is forecast over much of western and northern NY and northwestern Pennsylvania while a few inches of snow is likely over the Tug Hill Region.

The Meteorological Service of Canada has issued red (the highest level on a three-tier scale) extreme cold, blizzard, and snowfall warnings for much of Manitoba, northern Ontario, western Quebec, and northern Saskatchewan provinces, as well as southern Nunavut Territory. Blowing snow advisories are in effect for southern Manitoba Province, while authorities have issued weather advisories for strong winds and snow for southern and central Ontario Province. Officials could update and possibly extend the coverage of the relevant weather alerts over the coming days.

Hazardous Conditions
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 are likely to lead to periods of blowing and drifting snow. Blizzard conditions are possible. Sporadic power outages are possible throughout the affected area.

Transport and Utilities
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. Difficult and potentially dangerous driving conditions are also likely on secondary and rural roadways in the affected states as maintenance crews prioritize clearing major routes. Authorities could close stretches of highway if driving conditions become too hazardous. Gusty winds may threaten to topple high-profile vehicles throughout the affected area. Heavy wet snow and strong winds could bring down power lines and trees with foliage. Flight delays and cancellations are likely due to ground stops and deicing operations at regional airports.

Advice

Monitor local media for updated weather information. Verify road conditions before driving in areas where heavy snowfall is forecast. Allow extra time to reach destinations in these areas and carry an emergency kit and warm clothes if driving is necessary, especially on secondary or rural routes that could become impassable. Plan accordingly for delivery delays if routing shipments by truck through the affected area. Confirm flights. Charge battery-powered devices in the case of prolonged electricity outages.
