Photos are happy occasions. A dad with two children on vacation. Family pets with wagging tails. Teenage girls posing for selfies.

This is a gallery of the missing. DANA Desaparecidos is a social media effort to find those still missing from the devastating flash floods that swept through eastern Spain. At least 217 people have died and the toll could rise further.

In a miraculous rescue, a woman was found alive on Saturday after being trapped in her car for three days. However, hopes are fading for those who remain missing.

Although the government has not released the number of people still missing, social media accounts such as DANA Desaparecidos have received dozens of reports of families in distress searching for their loved ones. Many communities have been cut off from all communication for days.

The government telephone line responsible for reporting missing people following the floods has been completely overwhelmed. Instead, their families and friends took to social media to spread the message.

On DANA Desparecidos, each photo contains a description of one of the people currently missing and details of their last known location. Others post photos of missing animals, their owners desperate to find animal companions.

One photo shows a woman hugging a friend, with a caption that reads: “Her name is Mila. She left Picanya yesterday at 7 p.m. to go to her home in Silla. She never arrived.

Alba Lozano Asencio created the account with her boyfriend Luciano Esguerra. So far, around 30 people and a number of pets have been located, according to DANA Desaparcideo organizers. Messages titled “Localizado” – or “located” – are posted to inform users when a person has been found, often simply cut off from communication. Now they are also receiving requests for help with flood cleanup.

“People feel helpless and emergency services are overwhelmed,” Asencio told CNN. “I think an important part of the page is that it gives people some kind of hope right now.”

The slow and uncoordinated response to the crisis has sparked anger and frustration among many people here in Valencia.

King Felipe of Spain and Queen Letizia were reprimanded by angry residents during a visit Sunday to the hard-hit area of ​​Paiporta. Letizia, in particular, appeared shaken by the cries of “murderers” as mud was thrown at the royal couple. Spanish Prime Minister Pedro Sanchez was also present but was quickly evacuated by security.

The Spanish government announced on Monday that it was deploying 2,500 additional troops to the eastern region, in response to local fury.

By Monday evening, the army expects some 7,800 troops to be present in the area, according to the head of Spain’s military emergency unit, Francisco Javier Marcos. This is in addition to the 5,223 members of the Civil Guard and the 4,256 agents of the National Police already mobilized.

Security forces are searching for victims in ravines and underground garages, including in a large parking lot at the Bonaire shopping center in Aldaia.

The army also deployed a warship to Valencia, carrying helicopters, boats, trucks, food and emergency supplies.

Meanwhile, thousands of volunteers also continue to travel to affected areas, many of them walking long distances through the mud to help their neighbors.

Pedro de Juan, 18, had only seen scenes like this in movies, but he showed up with a broom and bucket to help.

“It’s amazing how the government says it’s not our fault. It’s someone else’s fault. But right now we need to come together and help each other,” he told CNN. “The army and police are helping us, but not as much as we hoped and they are several days late. »

“Frustrating is the word,” said Francisco Bosque, another volunteer who hopes to help his friends in flooded areas. “We feel completely helpless. All you can do is come here and introduce yourself.

The weather system that triggered the flooding continues to impact the area and some volunteer buses have been turned away as a precaution.

Spain’s AEMET service issued a red alert for the Barcelona region due to heavy rain until Monday afternoon, but the alert has since passed. Barcelona City Hall also published a flood warning on its website, urging people to take care and avoid areas that may be flooded.

Airport operator AENA said 70 flights from Barcelona’s El Prat airport were canceled or seriously delayed, while another 18 were diverted due to the storm. The weather conditions also affected train and metro services accessing the airport, the operator said.

A video posted on social media showed one of the airport buildings partially submerged due to heavy downpours, with water pouring through parts of the roof and some passengers wading through ankle-deep water.

AEMET also issued a new yellow and orange alert for the Castellon, Valencia and Alicante regions, warning that sudden heavy rains could cause more flooding in already devastated areas.
