Travelers across much of the eastern United States on Thursday braced for one of the most dangerous Christmas weekends in decades, with forecasters warning of a “bomb cyclone” that would bring heavy snow and strong winds as temperatures drop.
National Weather Service meteorologist Ashton Robinson Cooke said cold air is moving east across the central United States and about 135 million people will be affected by cold wind warnings in the coming days. Flights and train traffic in general were disrupted.
“This is not like the snowy days when you were a kid,” President Joe Biden warned in the Oval Office on Thursday after a briefing by federal officials. “This is a serious matter.”

In South Dakota, Rosebud Sioux Tribal Emergency Manager Robert Oliver said tribal authorities were working to clear roads so they could deliver propane and firewood to homes, but were faced with unforgiving winds that caused snowdrifts over 10 feet in some places. He said five people have died in recent storms, including last week’s snowstorm. Oliver didn’t give any details other than to say the family was in mourning.
On Wednesday, emergency management teams managed to rescue 15 people stranded in their homes but had to stop early Thursday morning as hydraulic fluid on heavy equipment froze in minus 41-degree winds.

“I think confidence will be gained over the next few days because people see that we have ultra-low temperatures and the network will be able to work easily,” he told reporters on Wednesday.
The cold weather has spread to El Paso and across the border to Ciudad Juarez, Mexico, where migrants have camped or filled shelters awaiting a decision on whether the United States will lift restrictions that have kept many from seeking shelter.
In other parts of the country, authorities feared power outages and warned people to take precautions to protect the elderly and the homeless and livestock, and to postpone travel where possible.
Michigan State Police are preparing to send additional officers to help motorists.
