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.
It’s 5.30am, but the car park outside a laundrette in south central Los Angeles is already bustling.
A woman is setting up a stand selling tacos on the pavement and the sun is beginning to rise behind the palm trees.
A group of seven women and two men are gathered in a circle, most wearing khaki green t-shirts.
The leader, a man named Francisco “Chavo” Romero, begins by asking how everyone is feeling. “Angry,” a few of them respond. “Proud of the community for pushing back,” says another.
Ron, a high school history teacher, issues a rallying cry. “This is like Vietnam,” he says. “We’re taking losses, but in the end we’re going to win. It’s a war.”

This is what the resistance against Donald Trump’s immigration policy looks like here. In the past month, immigration and customs enforcement agents – known as ICE – have intensified their raids on homes and workplaces across Los Angeles.
Since the beginning of June, nearly 2,800 undocumented immigrants have been arrested in the city, according to the Department of Homeland Security. The previous monthly high was just over 850 arrests in May this year.

Videos have circulated online of people being tackled to the ground in the car park of DIY shops, in car washes and outside homes. The videos have prompted outrage, protests and a fightback.
“Chavo” and Ron belong to a group of organised volunteers called Union del Barrio. Every morning, a group of them meet, mostly in areas which have high immigrant populations.
The day I meet them, they’re in an area of LA which is heavily Latino. Armed with walkie talkies to communicate with each other, megaphones to warn the community and leaflets to raise awareness they set out in cars in different directions.

They’re looking for cars used by ICE agents to monitor “targets”.
“That vehicle looks a little suspicious,” says Ron, pointing out a white SUV with blacked-out windows, “but there’s nobody in it”.
An elderly Latino man is standing on a street corner, cutting fruit to sell at his stall. “He’s the exact target that they’re looking for,” Ron says. “That’s what they’re doing now. The low-hanging fruit, the easy victim. And so that is proving to be more successful for their quotas.”

In the end, it turns out to be a quiet morning in this part of LA, no brewing immigration operations. But elsewhere in the city, dawn raids are happening.
ICE agents are under pressure from the White House to boost their deportation numbers in line with Donald Trump’s campaign promise to crack down on illegal immigration.

In June, tear gas and rubber bullets were fired at protestors demonstrating against immigration raids
Maria’s husband Javier was one of those arrested in LA. He came to the United States from Mexico when he was 19 and is now 58.
The couple have three grown-up children and two grandchildren. But Javier’s work permit expired two years ago, according to Maria and so he was living here illegally.

She shows me a video taken last month when Javier was at work at a car wash in Pomona, an area of LA. He is being handcuffed and arrested by armed and masked ICE agents, forced into a car. He is now being held at a detention centre two hours away.
“I know they’re doing their job,” she says, “but it’s like, ‘you don’t have to do it like that.’ Getting them and, you know, forcing people and pushing them down on the ground. They’re not animals.”

US troops accused of ‘political stunt’ after park raid
Maria wipes away tears as she explains the impact of his absence for the past four weeks. “It’s been so hard without him,” she says. “You feel alone when you get used to somebody and he’s not there any more. We’ve never been apart for as long as this.”
The family have a lawyer and is appealing for him to remain in the US, but Maria fears he will be sent back to Mexico or even a third country.

“I don’t know what to say to my grandkids because the oldest one, who is five was very attached to his papas, as he calls him. And he’s asking me, ‘When is papa coming home?’ and I don’t know what to say. He’s not a criminal.”
The fear in immigrant communities can be measured by the empty restaurant booths and streets that are far quieter than usual.

I meet Soledad at the Mexican restaurant she owns in Hollywood. When I arrive, she’s watching the local news on the TV as yet another raid unfolds at a nearby farm.
She’s shaking her head as ICE agents face off with protesters and military helicopters hover overhead. “I am scared. I am very scared,” she says.
All of her eight employees are undocumented, and four of them are too scared to come into work, she says, in case they get arrested. The process to get papers, she says, is too long and too expensive.

“They call me and tell me they are too afraid to come in because immigration is around,” she says.
“I have to work double shifts to be able to make up for their hours, and yes, I am very desperate, and sometimes I cry… We have no sales, and no money to pay their wages.”
There is just one woman eating fajitas at a booth, where there would usually be a lunchtime rush. People are chilled by the raids.

Soledad says she plans to hide her illegal workers if immigration officials arrive.
“I’ve told them, get inside the fridge, hide behind the stove, climb up where we have a space to store boxes, do not run because they will hunt you down.”
The White House says they’re protecting the country from criminals. ICE agents have been shot at while carrying out operations, their work becoming more dangerous by the day.
The tension here is ratcheting up. Deportation numbers are rising too. But the order from Donald Trump is to arrest even more people living here illegally.
Two people are dead after multiple people were injured in shootings in Kentucky, the state’s governor has said.
