A powerful winter storm is expected to blanket much of the US with heavy snow and life-threatening wind chills.
The storm is set to hit the country on Wednesday, likely sparking holiday travel chaos for millions of Americans.
About 200 million people are under extreme weather alerts as cold air descends from the Northern Plains, causing temperatures to nosedive, said Bob Oravec, a forecaster with the National Weather Service.
He said “rapid temperature drops, sometimes 50 or more degrees (Fahrenheit) colder than the previous day,” were likely, adding “it’s a pretty powerful, powerful system”.
The storm, fed by moisture from the Great Lakes, could dump up to a foot of snow on the Upper Midwest between Wednesday and Friday, with blizzard conditions stretching from the Northern Plains states to the Great Lakes region.
By Thursday night, a so-called “bomb cyclone” will likely form along the strong Arctic front across the Great Lakes, sending pressure sharply lower in a 24-hour period, potentially driving temperatures to record-breaking lows on the Gulf Coast and in Florida and the eastern US by Friday, Oravec said.
Heavy rainfall, strong winds and potentially dangerous coastal flooding are in store for parts of the northeast coastline and New England on Thursday and Friday, the weather service said, before the Arctic front arrives and causes a freeze. As much as 7.6cm of rain is predicted.

Officials are warning of severe travel disruption due to the weather. With temperatures dropping more than 11C (20F) within hours, wet roads could suddenly turn to ice, the weather service warned.
“We had a great Thanksgiving week with minimal disruption. Unfortunately, it’s not going to be that way going into Christmas,” US transportation secretary Pete Buttigieg told MSNBC.

Americans traveling by air should prepare for delays and be flexible in their plans, while drivers also need to be prepared for severe weather, he added.
Southwest Airlines said it has cancelled 500 of its 4,000 scheduled flights on Thursday and Friday. The company said it wanted to maintain safe operations for both passengers and crew.
At least 145 flights into or out of Denver International Airport were cancelled Wednesday as the city was hit with snow, gusty winds and freezing temperatures, according to FlightAware, a flight tracking company. At least 219 flights into or out of Denver were expected to be cancelled Thursday.
FlightAware was also expecting at least 364 flights to be cancelled Thursday at O’Hare and Midway airports in Chicago. Earlier this week, those two airports said they had 350 pieces of snow removal equipment and 400,000 gallons of pavement de-icing fluid on hand for the storm.
Delta, American, United, Frontier, Alaska, Southwest and other airlines were waiving change fees and offering travellers the option of choosing new flights to avoid the bad weather.
The deployment of National Guard soldiers on to the streets of LA by Donald Trump was always deeply controversial – and now it has been deemed illegal, too, by a federal judge.
In late spring in Los Angeles, I observed as peaceful protests against immigration raids turned confrontational.
I watched as Waymos – self-driving cars – were set alight and people waving flags shut down one of the city’s busiest freeways. I saw government buildings spray-painted with anti-government sentiment and expletives. Some people even threw bottles at police officers in riot gear.
In exchange, I saw law enforcement deploy “flash bang” crowd control devices and fire rubber bullets into crowds, indiscriminately, on occasion.

But Trump sent them in anyway, against the wishes of the local government. LA mayor Karen Bass condemned the deployment as an act of political theatre and said it risked stoking tensions.
The language Trump used was, arguably, inflammatory, too. He described LA as an “invaded” and “occupied city”. He spoke of “a full-blown assault on peace”, carried out by “rioters bearing foreign flags with the aim of continuing a foreign invasion of our country”.

Trump: ‘We will liberate Los Angeles’
It didn’t reflect reality. The size of the protests were modest, several thousand people marching through a handful of streets in downtown LA, a city which spans 500 square miles and has a population of almost four million.
The majority of the soldiers simply stood guard outside government buildings, often looking bored. Some of them are still here, with nothing to do. Now a judge has ruled that the operation was illegal.
US District Judge Charles Breyer said the Trump administration “used armed soldiers (whose identity was often obscured by protective armour) and military vehicles to set up protective perimeters and traffic blockades, engage in crowd control, and otherwise demonstrate a military presence in and around Los Angeles”.

Marines head to Los Angeles
In a scathing judgement, he effectively accused the White House of turning National Guard soldiers and marines into a “national police force.”
That breaches a law from 1878, barring the use of soldiers for civilian law enforcement activities.
It is a blow to what some view as the president’s ambition to federalise Democrat-run cities and deploy the National Guard in other states around the country. He had threatened to send troops to Chicago as part of an initiative he says is cracking down on crime, widening the use of National Guard troops, as seen on the streets of Washington DC.

The fightback against immigration raids in LA
But since this judge ruled that the deployment of National Guard and marines to LA in June was unlawful in the way it unfolded, Trump may have to be inventive with his rationale for sending soldiers into other US cities in the future.
This legal judgement, though, is being appealed and may well be overturned. Either way, it is unlikely to stem the president’s ambition to act as national police chief.
A strike on what the US called a Venezuelan gang’s drug-carrying vessel killed 11 people, Donald Trump has said.
Speaking at a news conference at the White House, the US president told reporters: “We just, over the last few minutes, literally shot out a boat, a drug-carrying boat, a lot of drugs in that boat.
“And there’s more where that came from. We have a lot of drugs pouring into our country, coming in for a long time.”
Secretary of State Marco Rubio then added: “These particular drugs were probably headed to Trinidad or some other country in the Caribbean.
“Suffice to say the president is going to be on offence against drug cartels and drug trafficking in the United States.”
Mr Trump later posted a video on Truth Social of a vessel exploding, in what appeared to mark the first US military operation in the southern Caribbean to crack down on drug cartels.
The president said on social media that the US military had identified the crew as members of Venezuelangang Tren de Aragua, which was designated a terrorist group in February.
He then alleged that Tren de Aragua is being controlled by Venezuela’s President Nicolas Maduro, which the country denies.
Venezuelan officials have repeatedly said that Tren de Aragua is no longer active in their country after they dismantled it during a prison raid in 2023.
The US last month doubled its reward for information leading to the arrest of Mr Maduro to $50m, accusing him of links to drug trafficking and criminal groups.
The US has deployed warships in the southern Caribbean in recent weeks.
Seven warships, along with one nuclear-powered fast-attack submarine, are either in the region or expected to arrive soon, carrying more than 4,500 sailors and Marines.
Officials have said that the US military has also been flying P-8 spy planes over international waters in the region to gather intelligence.
Mr Maduro said on Monday that he “would constitutionally declare a republic in arms” if Venezuela were attacked by US forces deployed in the Caribbean.
