US: Adverse winter weather forecast across northern regions through at least Dec. 19
Adverse winter weather forecast over parts of the northern US through at least Dec. 19. Hazardous travel conditions likely.
Adverse winter weather is forecast across parts of the northern US through at least Dec. 19. A weather system moving eastward across the region is forecast to bring heavy snowfall and strong winds across the northern plains and into the Midwest and Great Lakes. Snowfall accumulations of 7.5-15 cm (3-6 inches) are expected across parts of eastern northern North Dakota and northwestern Minnesota. Hazardous travel conditions are likely due to reduced visibility caused by blowing snow.
As of early Dec. 18, the National Weather Service (NWS) has issued winter storm warnings across parts of northwestern Montana and winter storm watches are in place for parts of eastern and northern North Dakota, northeastern and northwestern Minnesota, and eastern and northwestern Wisconsin. Winter weather advisories have been issued for much of the rest of North Dakota and parts of north-central Idaho, northwestern Montana, and the Upper Michigan Peninsula. High wind warnings, watches, and advisories are in effect across much of the rest of the affected area. Officials could update and extend the coverage of the weather alerts over the coming days.
Snow accumulations are likely across the affected region, especially at higher elevations. Lesser accumulations are possible where sleet and freezing rain mix with the snow, and precipitation is less intense. In addition to the heavy snow, strong wind gusts will likely lead to periods of blowing and drifting snow in some areas. Sporadic power outages could occur throughout the affected region.
The winter weather will likely cause ground and air transport disruptions across the region. Traffic and commercial trucking delays are probable along regional highways. Dangerous and challenging driving conditions are likely on secondary and rural roads in the affected states as maintenance crews prioritize clearing major routes. Authorities will probably 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.
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 affected areas, plan accordingly for delivery delays. Confirm flights. Charge battery-powered devices in the case of prolonged electricity outages.
