As of the deadline, the Spanish flood has resulted in at least casualties. With the rescue operation entering its sixth day, Spain has mobilized tens of thousands of people to participate in the relief efforts, and most affected areas have restored electricity, gas, and communication networks. Reuters analysis suggests that a destructive weather system formed by the meeting of cold and warm air may be the primary cause of this flood.

Heavy rains hit southeastern Spain on the night of a certain date, causing severe flooding. The Spanish government said on a certain date that the floods had resulted in at least people dead, including in the Valencian Community, with the death toll expected to rise further. According to Reuters, this is the deadliest flood in Europe since 2000.

AFP reports that approximately 100,000 soldiers, police, national guardsmen, and firefighters have been deployed to distribute supplies, clear debris, and repair infrastructure in various rescue efforts. Local government officials stated that by the 10th, almost all electricity supply and 90% of the communication networks in the affected areas had been restored, 80% of the affected population had regained gas supply, and railway and road repairs were still ongoing.

When the flood struck, some people were trapped in cars in underground parking lots and tunnels, unable to escape in time, making it difficult to locate their remains. Divers used heavy machinery such as water pumps to clear the standing water, and with the help of drones and sniffer dogs, they searched for the bodies of the victims.

According to Reuters, a warship carrying marines and a convoy of trucks loaded with food and drinking water arrived at the Port of Valencia.

Spanish Justice Minister Félix Bolaños revealed on the evening of the day that the Spanish government is scheduled to hold a cabinet meeting on the day, designating some disaster-stricken villages in Valencia, Andalusia, Castilla-La Mancha, and Catalonia as "severely affected areas" in order to apply for emergency relief funds from the government. The meeting will also approve a package of relief measures to help the affected residents through their difficulties.

Valencian Community President Carlos Mazón said that plans are in place to distribute relief funds to affected towns and families within the region. He stated that the Valencia region will apply to the Spanish central government for a total of approximately one billion euros (equivalent to about 1.1 billion U.S. dollars) in relief funds, including funds for the reconstruction of key infrastructure.

According to Reuters analysis, the flood was triggered by massive rain clouds generated from the meeting of cold and warm air. This highly destructive weather system, known in Spain as "AIL", is an acronym for "Altitudinal Isolated Low Pressure" in Spanish. When cold air blows over the warm Mediterranean waters, warm air rises rapidly to form dense rain clouds. These rain clouds can linger in the same area for hours, thereby increasing the destructive power.

In the view of Professor Hannah Cloke, a hydrology expert at the University of Reading in the UK, the heavy rains and floods that Spain is currently experiencing are yet another "evidence" of climate change, "We will see more severe floods like this in the future."
