A massive winter storm roaring across the West dumped up to 4 feet of snow in parts of Nevada and Idaho, fueled blizzard warnings in six other states, and spawned tornadoes that injured several people in the South.

More than 25 million Americans were under dangerous weather watches and warnings Tuesday. The storm’s march across the nation could last through the weekend when parts of the northeast could be blasted with more than a foot of snow, forecasters warned.

“This is a ‘we are not kidding’ kind of storm,” the South Dakota Department of Transportation tweeted as it warned of road closures across much of the state. “BLIZZARD and ICE STORM WARNINGS have been issued. Rain/freezing rain and heavy snow coupled with high winds will impact travel.”

The powerful storm system left some southern communities in shambles. There were multiple reports of injuries in the south, mainly in Texas and Louisiana, as tornadoes and storms tore through the region.

6 states face blizzard conditions

Parts of Nebraska, Colorado, South Dakota, Montana, Wyoming, and Kansas were facing blizzard conditions – snow with winds of at least 35 mph, reducing visibilities to a quarter of a mile or less – and several other states faced winter storm and ice storm warnings, the National Weather Service said. 

The Nebraska Department of Transportation closed stretches of Interstate 80 and Interstate 76. The Nebraska State Patrol urged people to stay off the roads.

“There’s essentially no one traveling right now,” said Justin McCallum, a manager at the Flying J truck stop at Ogallala, Nebraska.

In Colorado, the weather service office in Boulder said state transportation department cameras showed “deteriorating conditions across the plains” Tuesday. The heaviest snow reported in the past 24 hours happened in the northern and western areas of the state, including 10 inches in Stoner and more than 8 inches in Steamboat Springs, according to AccuWeather.
