‘Sudden stratospheric warming’ forecast to hit northern Europe in January – but experts unsure where it will strike
The UK could find itself in the deep freeze in January due to a change in wind patterns high up in the atmosphere – the same phenomenon that blew in the bitterly cold Beast from the East in 2018.
However, forecasters are warning it is too soon to tell where in Europe the cold weather will strike.
The “increased likelihood” of a freezing spell is due to a phenomenon called a ‘sudden stratospheric warming’ (SSW) that is forecast for early January, which can bring plunging cold temperatures a week or so later.
Professor Liz Bentley, chief executive of the Royal Meteorological Society, said: “When you get an SSW it increases the likelihood of a prolonged cold spell across Northern Europe, like the Beast from the East.”
But it is “hard to say” exactly where it will hit, she said. “It could impact the UK, it has the potential to, but I wouldn’t like to say it’s likely to.”
But the Met Office urged more caution. Spokesperson Stephen Dixon said: “It’s too early to tell if there will be a sudden stratospheric warming (SSW) event at the moment.
“Forecast models suggest a much weakened polar vortex over the coming weeks, but it’s not clear if this will result in an SSW or exactly how this will influence the UK’s weather patterns at this range.”
What is Sudden Stratospheric Warming?
An SSW happens when polar vortex winds in the stratosphere – the layer of atmosphere at 10-50km above Earth – slow, stop or reverse direction.
This leads to rapid warming in the stratosphere by up to 50C, but a few weeks later this also disrupts the jet stream, which affects our weather lower down.
As the jet stream starts to “wobble”, it allows cold air usually locked above the Arctic to seep further south in some areas of the Northern Hemisphere, said Prof Bentley.

How will it affect our weather?
“Now the crux of what we are looking for is where the waves [in the jet stream] will be,” added Prof Bentley.
“When we have an SSW it increases the likelihood of a cold spell across a large region like Europe or North America, but we wouldn’t get a feel for the actual position until four or five days out.
“Exactly where is hard to pinpoint. But there is an increased likelihood of very cold spells for certain regions.”
Professor Andrew Charlton-Perez, a meteorologist from the University of Reading, said SSWs are also associated with “weaker westerlies for Europe and even easterlies, in some cases.”
“Given westerly winds tend to give more mild weather in winter, that can bring much colder weather across Western Europe.”
He added: “We know Europe will be cold, but it is difficult to be precise where, this far out.”

When will it happen?
An SSW is on the cards for the next week, but it takes another week or so after that before the knock-on impact on the jet stream.
A cold spell is forecast for the second week of January, but it could kick in later, or last until February, said Prof Bentley.
The current Met Office forecast for mid-January projects an “increased chance of colder than average conditions during this period, and a reduced chance of prolonged periods of very unsettled / milder conditions with frequent rain and wind pushing in from the Atlantic.
“Currently the chance of widespread severe cold is still deemed low, but still the risk of impacts from cold, ice and snow is greater than normal.”
Will the UK see another ‘Beast from the East’?
An SSW doesn’t always bring cold conditions to the UK, because it depends on where the jet stream “wobbles”.
The Beast from the East in 2018 was caused by an SSW that allowed cold air to flow in to the UK from Siberia in the east.
But another SSW in 2019 “didn’t have a strong influence on Europe”, said Prof Charlton-Perez.
In any case, the UK is likely to see more settled weather than the recent wind and rain, said Prof Bentley.
We see the boat from a distance – the orange of the life jackets reflected in the rising sun.
And as we draw closer, we can make out dozens of people crowded on board as it sets off from the shore, from a beach near Dunkirk.
.
There is no sign of any police activity on the shore, and there are no police vessels in the water.
Instead, the migrants crammed into an inflatable dinghy are being watched by us, on board a private boat, and the looming figure of the Minck, a French search and rescue ship that soon arrives.

The dinghy meanders. It’s not heading towards Britain but rather hugging the coast.
A few of the passengers wave at us cheerfully, but then the boat starts to head back towards the shore.
As it nears a different beach, we see a police vehicle – a dune buggy – heading down to meet it.
Normal practice is for French police officers to slice through the material of any of these small boats that end up back on shore.

Two police officers get out of the buggy and wait. A police helicopter arrives and circles above, performing a tight circle over the heads of the migrants.
The police think they might be about to go back on to the beach; in fact, these passengers know that most of them are staying put.
The boat stops a short distance from the shore and four people jump out. As they wade towards the beach, the boat turns and starts to head back out to sea.
We see the two police officers approach these four men and have a brief conversation.

They don’t appear to check the bags they are carrying and, if they do question them about why they left the boat, it is the most cursory of conversations.
In reality, these people probably don’t speak French but they were almost certainly involved in arranging this crossing, which is against the law. But all four walk away, disappearing into the dunes at the back of the beach.

Why do migrants want to come to the UK?
We follow the boat as it chugs off in the direction of Britain, carrying around 50 people.
The Minck returns to shadowing its progress, but its job is limited to offering help if the boat gets into trouble.
Otherwise, if the engine keeps working, then this flimsy vessel will reach British waters in a few hours’ time.

IDF chief says conditions ‘created’ for Gaza ceasefire – as Trump says it could be ‘this week or next’
Donald Trump and a leading figure in the Israeli army have suggested a ceasefire in Gaza could be close.
Eyal Zamir, chief of staff of the Israel Defence Forces (IDF), told Israeli media that “conditions were created to advance a deal” to bring about an end to the conflict in the coastal territory, and the release of hostages.
In a televised address, he said: “We have achieved many significant results, we have caused great damage to the governance and military capabilities of Hamas.
“Thanks to the operational power that we have demonstrated, the conditions have been created to advance a deal to release the hostages.”
‘This week, or next’
It comes as the US president hosts Israeli Prime Minister Benjamin Netanyahu in Washington DC on a prolonged visit this week.
Mr Trump said his meetings with Mr Netanyahu were focused “on Gaza for the most part”.
He said: “I think we have a chance [of a ceasefire] this week, or next week.”
However, the US leader added: “Not definitely,” saying nothing was certain about the situation in Gaza.

Hamas reiterates ‘keenness’ to end fighting
Meanwhile, Hamas has repeated its message that it is committed to the negotiations but warned of a number of sticking points despite the positive noises from senior Israeli figures.
In a statement, the militant group said: “In its keenness to succeed in the ongoing efforts, the movement [Hamas] has shown the necessary flexibility and agreed to release 10 prisoners.
“The key points remain under negotiation, foremost among them: the flow of aid, the withdrawal of the occupation from the territories of the Gaza Strip, and the provision of real guarantees for a permanent ceasefire.”

Mr Trump’s special envoy to the Middle East Steve Witkoff previously told a cabinet meeting that the anticipated ceasefire would last 60 days and involve the release of ten hostages and nine bodies.
A source close to the negotiations told Sky News that the hostage release would take place in two waves during the 60 days and was conditional on the ceasefire.

Israeli strikes continue
It comes as Israeli attacks on Gaza continue.
According to hospital officials, at least 40 Palestinians were killed in the latest attacks on Gaza – including 10 people from the same family.
Nasser Hospital in the southern Gaza city of Khan Younis said the dead included 17 women and 10 children.
While the politicians talk, so many people come from around the world to try to get across the Channel on small boats. But why?
Why make such a perilous crossing to try to get to a country that seems to be getting increasingly hostile to asylum seekers?
As the British and French leaders meet, with small boats at the forefront of their agenda, we came to northern France to get some answers.
It is not a new question, but it is peppered with fresh relevance.
Over the course of a morning spent around a migrant camp in Dunkirk, we meet migrants from Gaza, Iraq, Eritrea, South Sudan, Sri Lanka and beyond.
Some are fearful, waving us away; some are happy to talk. Very few are comfortable to be filmed.
All but one man – who says he’s come to the wrong place and actually wants to claim asylum in Paris – are intent on reaching Britain.
They see the calm seas, feel the light winds – perfect conditions for small boat crossings.
John has come here from South Sudan. He tells me he’s now 18 years old. He left his war-torn home nation just before his 16th birthday. He feels that reaching Britain is his destiny.
“England is my dream country,” he says. “It has been my dream since I was at school. It’s the country that colonised us and when I get there, I will feel like I am home.
“In England, they can give me an opportunity to succeed or to do whatever I need to do in my life. I feel like I am an English child, who was born in Africa.”
‘England is my dream country,’ John tells Adam Parsons
He says he would like to make a career in England, either as a journalist or in human resources, and, like many others we meet, is at pains to insist he will work hard.
The boat crossing is waved away as little more than an inconvenience – a trifle compared with the previous hardships of his journey towards Britain.
We meet a group of men who have all travelled from Gaza, intent on starting new lives in Britain and then bringing their families over to join them.
One man, who left Gaza two years ago, tells me that his son has since been shot in the leg “but there is no hospital for him to go to”.
Next to him, a man called Abdullah says he entered Europe through Greece and stayed there for months on end, but was told the Greek authorities would never allow him to bring over his family.
Britain, he thinks, will be more accommodating. “Gaza is being destroyed – we need help,” he says.
Abdullah says ‘Gaza is being destroyed – we need help’
A man from Eritrea tells us he is escaping a failing country and has friends in Britain – he plans to become a bicycle courier in either London or Manchester.
He can’t stay in France, he says, because he doesn’t speak French. The English language is presented as a huge draw for many of the people we talk to, just as it had been during similar conversations over the course of many years.
I ask many of these people why they don’t want to stay in France, or another safe European country.
Some repeat that they cannot speak the language and feel ostracised. Another says that he tried, and failed, to get a residency permit in both France and Belgium.
But this is also, clearly, a flawed survey. Last year, five times as many people sought asylum in France as in Britain.
And French critics have long insisted that Britain, a country without a European-style ID card system, makes itself attractive to migrants who can “disappear”.

Migrant Channel crossings hit new record
A young man from Iraq, with absolutely perfect English, comes for a chat. He oozes confidence and a certain amount of mischief.
It has taken him only seven days to get from Iraq to Dunkirk; when I ask how he has made the trip so quickly, he shrugs. “Money talks”.
He looks around him. “Let me tell you – all of these people you see around you will be getting to Britain and the first job they get will be in the black market, so they won’t be paying any tax.
“Back in the day in Britain, they used to welcome immigrants very well, but these days I don’t think they want to, because there’s too many of them coming by boat. Every day it’s about seven or 800 people. That’s too many people.”
“But,” I ask, “if those people are a problem – then what makes you different? Aren’t you a problem too?”
He shakes his head emphatically. “I know that I’m a very good guy. And I won’t be a problem. I’ll only stay in Britain for a few years and then I’ll leave again.”
A man from Sri Lanka says he “will feel safe” when he gets to Britain; a tall, smiling man from Ethiopia echoes the sentiment: “We are not safe in our home country so we have come all this way,” he says. “We want to work, to be part of Britain.”
Emmanuel is another from South Sudan – thoughtful and eloquent. He left his country five years ago – “at the start of COVID” – and has not seen his children in all that time. His aim is to start a new life in Britain, and then to bring his family to join him.
He is a trained electrical engineer, but says he could also work as a lorry driver. He is adamant that Britain has a responsibility to the people of its former colony.

“The British came to my country – colonising, killing, raping,” he said. “And we didn’t complain. We let it happen.
“I am not the problem. I won’t fight anyone; I want to work. And if I break the laws – if any immigrant breaks the laws – then fine, deport them.
“I know it won’t be easy – some people won’t like me, some people will. But England is my dream.”
