Why flooding in Spain has been so deadly – and why it could happen again
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.

Deadly flood damage is ‘utterly random’
Deadliest weather events were fuelled by climate change
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.
At least 11 people have been killed and 63 injured in an Israeli strike on central Beirut, Lebanese authorities have said.
Lebanon‘s health ministry said the death toll could rise as emergency workers dug through the rubble looking for survivors. DNA tests are being used to identify the victims, the ministry added.
State-run National News Agency (NNA) said the attack “completely destroyed” an eight-storey residential building in the Basta neighbourhood early on Saturday.
Footage broadcast by Lebanon’s Al Jadeed station also showed at least one destroyed building and several others badly damaged around it.

The Israeli military did not warn residents to evacuate before the attack – the fourth targeting the centre this week.
At least four bombs were dropped in the attack, security sources told Reuters news agency.
The blasts happened at about 4am (2am UK time).
A seperate drone strike in the southern port cuty of Tyre this morning killed one person and injured another, according to the NNA.
The blasts came after a day of bombardment of Beirut’s southern suburbs and Tyre. The Israeli military had issued evacuation notices prior to those strikes.

Israel has killed several Hezbollah leaders in air strikes on the capital’s southern suburbs.
Heavy fighting between Israel and Hezbollah is ongoing in southern Lebanon, as Israeli forces push deeper into the country since launching a major offensive in September.

US envoy Amos Hochstein was in the region this week to try to end more than 13 months of fighting between Israel and Hezbollah, ignited last October by the war in Gaza.
Mr Hochstein indicated progress had been made after meetings in Beirut on Tuesday and Wednesday, before going to meet Israeli Prime Minister Benjamin Netanyahu and defence minister Israel Katz.
According to the Lebanese health ministry, Israel has killed more than 3,500 people in Lebanon and wounded more than 15,000.
It has displaced about 1.2 million people – a quarter of Lebanon’s population – while Israel says about 90 soldiers and nearly 50 civilians have been killed in northern Israel.

Vladimir Putin vows to increase production of Russia’s ‘unstoppable’ missile – as NATO and Ukraine to hold talks
President Vladimir Putin has said Russia will ramp up the production of a new, hypersonic ballistic missile.
In a nationally-televised speech, Mr Putin said the intermediate-range Oreshnik missile was used in an attack on Ukrainian city Dnipro in retaliation for Ukraine’s use of US and British missiles capable of striking deeper into Russian territory.
Referring to the Oreshnik, the Russian president said: “No one in the world has such weapons.
“Sooner or later other leading countries will also get them. We are aware that they are under development.”

He added: “We have this system now. And this is important.”
Detailing the missile’s alleged capabilities, Mr Putin claimed it is so powerful that using several fitted with conventional warheads in one attack could be as devastating as a strike with nuclear weapons.
General Sergei Karakayev, head of Russia’s strategic missile forces, said the Oreshnik could reach targets across Europe and be fitted with either nuclear or conventional warheads – while Mr Putin alleged Western air defence systems will not be able to stop the missiles.
Mr Putin said of the Oreshnik: “There is no countermeasure to such a missile, no means of intercepting it, in the world today. And I will emphasise once again that we will continue testing this newest system. It is necessary to establish serial production.”

Testing the Oreshnik will happen “in combat, depending on the situation and the character of security threats created for Russia“, the president added, stating there is “a stockpile of such systems ready for use”.
NATO and Ukraine are expected to hold emergency talks on Tuesday.
Meanwhile Ukraine’s parliament cancelled a session as security was tightened following the strike on Dnipro, a central city with a population of around one million. No fatalities were reported.

Russia’s new missile – what does it mean?
Speaking in Kyiv, Czech foreign minister Jan Lipavsky called Moscow’s strike an “escalatory step and an attempt of the Russian dictator to scare the population of Ukraine and to scare the population of Europe”.
At a news conference, Mr Lipavsky gave his full support for delivering the additional air defence systems needed to protect Ukrainian civilians from the “heinous attacks”.
