The United States National Weather Service said as much as 2 feet (61 centimeters) of snow was possible in some areas of western South Dakota and northwestern Nebraska
A massive storm blowing across the country has spawned several tornadoes that wrecked buildings and injured a handful of people in Oklahoma and Texas.
The storm and tornadoes have left two people missing in Louisiana and saw much of the central United States bracing for blizzard-like conditions, several media reports suggested.
Rescue teams including firefighters, volunteers and dog teams were searching the debris after a tornado touched down about 10 miles (16 kilometers) from Shreveport, Louisiana officials said. Two people were missing, one was hurt and several buildings were destroyed, they added.
Far to the northwest US, an area stretching from Montana into western Nebraska and Colorado was under blizzard warnings, and the United States National Weather Service said as much as 2 feet (61 centimeters) of snow was possible in some areas of western South Dakota and northwestern Nebraska, news agency AP reported. Ice and sleet were expected in the eastern Great Plains.
As per the forecasts the storm system is expected to hobble the upper Midwest with ice, rain and snow for days, as well as move into the Northeast and central Appalachians.
Residents from West Virginia to Vermont were told to watch out for a possible significant mix of snow, ice and sleet, and the National Weather Service issued a winter storm watch from Wednesday night through Friday afternoon, depending on the timing of the storm.
