More than 200 people have died in Spain after nearly a year’s worth of rain fell in a matter of hours.
On Friday, there were at least 205 confirmed deaths in Valencia, two in Castilla La Mancha, and one in Andalusia.
Local authorities issued warnings late on Tuesday, but many say this gave them next-to-no time to prepare for the conditions that had killed dozens by Wednesday.
Here we look at what caused the flooding – and why they could happen again.
How quickly did the floods hit?
Heavy rain had already begun in parts of southern Spain on Monday.
In contrast to areas like Malaga, where residents told Sky News it had been “chucking it down for two days”, the rain did not start in the worst-hit region of Valencia until around 7pm on Tuesday.
At 8pm, people in Valencia received smartphone alerts warning them not to leave their homes.

But by then, many were already trapped in dangerous conditions, particularly in the south of the city where a major road had flooded, leaving drivers stuck in their cars.
By Wednesday morning, more than 50 people had been found dead.
The Chiva area of Valencia had been hit by 491 litres per square metre of rain in eight hours. Only around 65 l/m2 usually falls in the whole of October.
Storms spread west on Wednesday night and into Thursday, bringing deadly conditions to Andalusia and Castilla La Mancha as well.
What caused them?
Heavy rain is not uncommon across eastern Spain at this time of year.
It’s caused by a weather phenomenon called DANA – ‘depresion aislada en niveles altos’ in Spanish – which translates as ‘isolated low-pressure system at high levels’.
DANA occurs when:
1) Cold air from the north moves south;
2) Warm air then blows over the Mediterranean, rising quickly and forming heavy clouds;
3) The low pressure from the north gets blocked by the high pressure above the water, causing it to slow down or stop completely.

This creates storm-like conditions that cannot move anywhere else – so the rain falls over the same area for a sustained period of time.
What role did climate change play?
General flash floods and those caused by DANA specifically have struck Spain long before humans started warming the climate.
But climate change is making heavy rain worse, and therefore more dangerous.
That’s because hotter air is able to hold more moisture. So when it rains, it unleashes more water.
The current 1.3C increase in global temperatures since pre-industrial times means the air can carry about 9% more moisture.

What caused the floods in Spain?
And higher sea surface temperatures in the Mediterranean are a “key driver” of strong storms, said Dr Marilena Oltmanns, research scientist at the National Oceanography Centre in Southampton.
The world is on track for 3.1C warming by the end of this century, which is expected to make rain heavier still, increasing the chances of flash flooding and giving areas little time to respond.
Imperial College London’s lead for its World Weather Attribution (WWA) group Dr Friederike Otto says there is “no doubt about it”.
“These explosive downpours were intensified by climate change,” she says.
Professor Mark Smith, an expert in water science and health at the University of Leeds, adds that hotter summers also dry out the soil in the ground, which means it absorbs less rain – and more of it flows into rivers and lakes – which flood quicker.

Will they keep happening?
A red weather warning is in place for the Huelva area of Andalusia until Friday afternoon.
Beyond the warning period, storms are set to continue across parts of Spain for several days.
In the longer term, Dr Marilena Oltmanns says: “Given the long-term warming trend, both in the sea surface temperatures in the Mediterranean region and the global air temperature, we expect the events like the currently observed one in Spain to become more frequent.”
Chiva and the surrounding worst-hit area also suffers from the unfortunate geography of being in a river catchment – where water feeds into the River Turia – and close to the mountains. And is not far from the sea.
That means water has little chance to absorb into the land and so builds up very quickly.

This makes it all the more imperative that forecasts are accurate, authorities prepare accordingly, and residents respond quickly.
Professor Hannah Cloke, professor of Hydrology at the University of Reading, describes people dying in their cars and being swept away in the street as “entirely avoidable”.
“This suggests the system for alerting people to the dangers of floods in Valencia has failed,” she says.
“People need to understand that extreme weather warnings for floods are very different from regular weather reports. We need to consider flood warnings totally differently, more like fire alarms or earthquake sirens, and less like the way we browse daily weather forecasts on our phones or on the TV.”

Residents: ‘No one came to rescue us’
Gareth Redmond-King, international analyst at the Energy & Climate Intelligence Unit (ECIU), says Spain’s tragedy should serve as a “wake-up call” to the UK.
“This is not about future events in a far-off place with a dramatically different climate from the UK. Spain is one of our nearest neighbours,” he warns.
US President Donald Trump has told Gazans to hand over Israeli hostages or “you are dead”.
The threat, made over social media, came hours after the White House confirmed that US officials had broken with tradition to hold direct talks with Hamas.
The US has previously avoided direct contact with the group owing to Washington’s longstanding position not to negotiate with terrorists – with Hamas having been designated as a terrorist group in the US since 1997.
In a press conference on Wednesday, White House press secretary Ms Keavitt said there had been “ongoing talks and discussions” between the US officials and Hamas.

But she would not be drawn on the substance of the talks – taking place in Doha, Qatar – between US officials and Hamas, but said Israel had been consulted.
Ms Leavitt continued: “Dialogue and talking to people around the world to do what’s in the best interest of the American people, is something that the president has proven is what he believes is a good faith, effort to do what’s right for the American people.”
There are “American lives at stake,” she added.
Adam Boehler, Mr Trump’s pick to be special envoy for hostage affairs, participated in the direct talks with Hamas.
A spokesperson for Benjamin Netanyahu’s office said Israel had “expressed to the United States its position regarding direct talks with Hamas”.
Hours later, Mr Trump warned Hamas to hand over Israeli hostages or “it’s over for you” – adding: “This is your last warning”.

On his Truth Social platform, Mr Trump wrote: “Release all of the hostages now, not later, and immediately return all of the dead bodies of the people you murdered or it is over for you.
“Only sick and twisted people keep bodies and you are sick and twisted. I am sending Israel everything it needs to finish the job, not a single Hamas member will be safe if you don’t do as I say.”
Mr Trump met with freed Israeli hostages on Wednesday, something he referenced in his social media post, before adding: “This is your last warning. For the leadership of Hamas, now is the time to leave Gaza, while you still have a chance.
“Also, to the people of Gaza, a beautiful future awaits, but not if you hold hostages. If you do, you are dead. Make a smart decision. Release the hostages now, or there will be hell to pay later.”
Israel estimates about 24 living hostages, including American citizen Edan Alexander, and the bodies of at least 35 others, are still believed to be in Gaza.

The US has a long-held policy of not negotiating with terrorists – which it is breaking with these talks as Hamas has been designated a foreign terrorist organisation by the US government’s National Counterterrorism Center since 1997.
The discussions come as a fragile Israel-Hamas ceasefire continues to hold, but its future is uncertain.

Mr Trump has signalled he has no intention of pushing the Israeli prime minister away from a return to combat if Hamas does not agree to terms of a new ceasefire proposal – which, Israel says, has been drafted by US Middle East envoy Steve Witkoff.
The new plan would require Hamas to release half its remaining hostages – the group’s main bargaining chip – in exchange for a ceasefire extension and a promise to negotiate a lasting truce.
Donald Trump has admitted his tariffs on major trading partners will cause “a little disturbance” – as China said it was “ready” for “any type of war” with the US.
The US president made his comments in an address to Congress, hours after the levies on imports came into effect.
Producers in Mexico and Canada have been hit with a 25% tax on items they export to the US, while a 20% tariff has been applied to Chinese imports.

Stock markets, which Mr Trump is said to pay close attention to, slid on the tariffs news.
Exporters in the affected countries as well as businesses in the US and economists have raised concerns about the potential price-raising impact of the tariffs.
Making imports more expensive will likely make goods more expensive and could push prices up across the board.

Trump’s Congress speech unwrapped
Concern over threat to interest rates
A cycle of high inflation could lead to interest rates being higher for longer in the US, the world’s largest economy, which could dampen economic activity.
A slowed US economy would have global consequences but even without a hit to the States, there are fears of a global trade war – in which countries add their own trade barriers in the form of tariffs.
The Chinese embassy in the US posted on X: “If war is what the US wants, be it a tariff war, a trade war or any other type of war, we’re ready to fight till the end.”

Speaking to Sky News presenter Yalda Hakim the US former deputy national security advisor Matt Pottinger said Chinese president Xi Jinping was turning the Chinese economy “into a wartime economy”
“He’s preparing his economy for war so that it can withstand the shocks of war,” he said on The World with Richard Engel and Yalda Hakim podcast
“That means he’s willing to undergo massive inefficiencies in the economy. He’s willing to stockpile food that otherwise would flow easily and more cheaply in from foreign vessels.”
“He’s stockpiling copper and all kinds of inputs into the economy. He is making sure that the private sector is wholly aligned with his broad goals, which are about increasing the Chinese Communist Party’s control over the economy and creating a bigger, better defence industrial base,” Mr Pottinger said.
“He’s preparing for war.”

Canada’s prime minister Justin Trudeau said his country was launching its own WTO challenge and described the US tariffs as a “dumb thing to do”.
He also warned the move by the Trump administration would impact American workplaces and add to inflation in the US.
Addressing the American public, he said: “We don’t want this… but your government has chosen to do this to you.”
Canada has announced the imposition of 25% tariffs on US imports worth C$30bn (£16.3bn).
But US commerce secretary Howard Lutnick struck a different note on tariffs and on Monday said the president will “probably” announce a compromise with Canada and Mexico as early as Wednesday.
China’s premier has warned “changes unseen in a century are unfolding across the world” as a trade war with the US intensifies.
Li Qiang was speaking in parliament – a day after Washington slapped another 10% tariff on Chinese goods.
Beijing has responded with 10% to 15% tariffs on US food and agricultural products.
“Global economic growth lacks steam, unilateralism and protectionism are on the rise… the multilateral trading system is experiencing disruptions and tariff barriers continue to increase,” Premier Li added.

‘Whatever they tariff us, we will tariff them’
The Chinese Embassy in the US has also dialled up the pressure, writing on X: “If war is what the US wants, be it tariff war, a trade war or any other type of war, we’re ready to fight till the end.”
This statement was first made by China’s ministry of foreign affairs on Tuesday. The fact that China has repeated it two days in a row is significant.
It is a pointed message to the US that China’s patience is running out – and its rhetoric about the tit-for-tat tariffs is growing harsher. It has called the tariff war “pressure”, “blackmail”, a “smear campaign” and “shifting the blame”.
But Mr Trump loves imposing tariffs on China and appears convinced the pressure will work. He blames China for exporting the chemical precursors used to make fentanyl, which has fuelled the US opioid epidemic.
Meanwhile, China is facing severe economic challenges at home, with the country setting a growth target of “about 5%” for this year.
The government’s work report said a major task this year is to boost consumption and domestic demand.

Why are tariffs such a big deal?
The problem in China is people aren’t spending enough money, instead they are cautiously saving. One reason for this is the weakness of China’s social welfare system. People save their money in case they lose their job, or to pay for health and elderly care.
The government says it wants to make domestic demand the engine of growth by turning several cities into “international consumption centres” – and expanding its trade-in system to encourage people to buy new products for the home.
Shopping aside, thousands of delegates from provinces across China attended including high-profile figures like former basketball star Yao Ming, and Lei Jun, who co-founded the electric vehicle manufacturing company Xiaomi.
After the session, delegates streamed into the square outside the Great Hall of the People. It is a chance to get their thoughts on the country’s future.
Congress delegate Liu Hui said: “I think tariffs will have little impact on China because we treat others the way they treat us.”
Another delegate from Shaanxi province, Song Yaping, is proud of China’s hi-tech prowess and said: “Our technology develops so fast, just look at DeepSeek, look at how fast our AI develops.”

Peace in Europe, war with China?
Despite the confidence, the trade war is deepening.
In the factory heartland of Guangzhou in southern China, a glassware exporter is bracing for the impact of the latest Trump tariffs.
Marketing manager Anna said: “I think the people will discuss these tariffs and of course 10% is a huge number. Some companies can’t make a profit from this.
“But we can’t change it. We just have to get used to it and let it be.”
Still, letting it be is not easy in a world where it feels like everything is changing fast.
