US: Adverse winter weather forecast over parts of the Upper Midwest through at least Oct. 18

Adverse winter weather forecast across parts of the Upper Midwest, US, through at least Oct. 18. Hazardous travel conditions likely.

Warning

Event

Heavy snowfall is forecast in parts of the Upper Midwest around the Great Lakes through at least Oct. 18. Snowfall accumulations of around 10-20 cm (4-8 inches) are possible over parts of the Upper Peninsula of Michigan and far northern Wisconsin, with isolated amounts of around 30 cm (12 inches) in places. The lake effect snow could be accompanied by strong winds, leading to hazardous driving conditions due to icy roads and reduced visibility.

Government Advisories
As of Oct. 17, the National Weather Service (NWS) has issued winter storm warnings or watches and winter weather advisories across much of the affected area. Lakeshore flood warnings have also been issued for parts of the northeastern Upper Peninsula of Michigan. Officials could update and possibly extend the coverage of weather alerts over the coming days.

Hazardous Conditions
Snow accumulations are likely across the affected area. Lesser accumulations are possible where sleet and freezing rain mix with the snow, and precipitation are less intense. In addition to the heavy snow, strong wind gusts will likely lead to periods of blowing and drifting snow in some areas. Blizzard conditions are possible. Sporadic power outages could occur throughout the affected area.

Transport
The winter weather will likely cause ground and air transport disruptions over the coming days. Traffic and commercial trucking delays are possible along regional highways. Dangerous and challenging driving conditions are also likely on secondary and rural roads in the affected states as maintenance crews prioritize clearing major routes. Authorities could close stretches of highways if driving conditions become too hazardous. 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. If routing shipments by truck through the affected area, plan accordingly for delivery delays. Confirm flights. Charge battery-powered devices in the case of prolonged electricity outages.
