What you need to know about the floods that have killed more than 200 people in Spain

VALENCIA, Spain — Within minutes, floods caused by heavy rains in eastern Spain swept away almost everything in their path. With no time to react, people were trapped in vehicles, homes and businesses. Many died and thousands of livelihoods were shattered.

Six days later, authorities recovered 217 bodies, 213 of them in the eastern region of Valencia. They continued to search for an unknown number of missing people on Monday with the help of about 5,000 fresh soldiers who arrived over the weekend.

An angry mob in Paiporta, badly hit threw mud and other objects at the royal members of SpainPrime Minister Pedro Sánchez and regional officials when the leaders made their first visit on Sunday to the epicenter of the flood damage.

More rain is forecast for disaster areas, as well as further up the Mediterranean coast, where part of the Catalonia region around the city of Tarragona is on red alert.

The Spanish Navy transport ship “Galicia” arrived in the port of Valencia on Monday with 100 soldiers, helicopters and trucks loaded with food and water to help with the relief effort.

Thousands of volunteers they were helping to clear the thick layers of mud and debris that still covered houses, streets and roads, all while dealing with drinking water cuts and lack of basic goods. Inside some of the vehicles that the water washed away or trapped in underground garages, there were still bodies waiting to be identified.

Here are some things to know about Spain’s deadliest storm in living memory:

What happened?

The storms focused over the Magro and Turia river basins and in the Poyo riverbed produced walls of water that overflowed riverbanks, catching people unawares as they went about their daily lives late Tuesday and early Wednesday .

As long as you blinkmuddy water covered roads and railways and seeped into homes and businesses in towns and villages on the southern outskirts of Valencia. Drivers were forced to take shelter on the roofs of their cars, while residents took refuge on higher ground.

Spain’s national weather service said in the hard-hit town of Chiva, more rain fell in eight hours than in the last 20 months. calling the flood “extraordinary”. Other areas on the southern outskirts of Valencia did not rain before wiped out by the wall of water which overflowed the drains.

When the authorities sent alerts on mobile phones warning of the severity of the flooding and asking people to stay at home, many were already on the roads, working or covered in water in low-lying areas or underground garages, which have become death traps.

Why did these massive floods occur?

Scientists trying to explain what happened see two likely connections with human-caused climate change. One is that warmer air holds and then sheds more rain. The other is possible changes in the jet stream – the river of air above the earth that moves weather systems around the globe – that generates extreme weather.

Climate scientists and meteorologists said the immediate cause of the flooding was called a low-pressure storm system that migrated from an unusually wavy and stalled current. This system simply parked over the region and rained. This happens often enough that in Spain they call them DANA, the Spanish acronym for system, meteorologists said.

And then there is the unusually high temperature of the Mediterranean Sea. It had the warmest surface temperature on record in mid-August at 28.47 degrees Celsius (83.25 degrees Fahrenheit), said Carola Koenig of the Center for Flood Risk and Resilience at Brunel University London.

The extreme weather event came after Spain struggled with prolonged droughts in 2022 and 2023. Experts say drought and flood cycles are increasing with climate change.

Has this happened before?

Spain’s Mediterranean coast is used to autumn storms that can cause flooding, but this episode was the strongest flash flood event in recent memory.

Elders in Paiporta, at the epicenter of the tragedy, say Tuesday’s floods were three times worse than those in 1957, which left at least 81 dead. This episode led to the diversion of the Turia water course, which meant that a large part of the city was spared from these floods.

Valencia suffered two other major DANAs in the 1980s, one in 1982 with around 30 deaths and another five years later that broke rainfall records.

Flash floods also surpassed the flood that swept away a campsite along the Gallego River in Biescas, in the northeast, killing 87 people in August 1996.

What was the state’s response?

The management of the crisis, classified as level two on a scale of three by the Valencian government, is in the hands of the regional authorities, who can ask the central government for help in mobilizing resources.

About 7,500 soldiers, trucks, heavy road equipment and Chinook helicopters were deployed in addition to almost 10,000 additional police from the National Police and Civil Guard to help search for bodies, clean up thousands of destroyed cars and distribute aid helpful.

When many of those affected said they felt abandoned by the authorities, a wave of volunteers arrived to help. Carrying brooms, shovels, water and basic food, hundreds of people walked several kilometers to deliver supplies and help clean up the worst-hit areas.

Sánchez’s government will approve a disaster declaration on Tuesday that will allow quick access to financial aid. Mazón announced additional economic assistance.

Valencia’s regional government was heavily criticized for not sending flood warnings to mobile phones until 8pm on Tuesday, when flooding had already started in some places and long after the national weather agency had issued a red alert indicating heavy rains.
