'Extreme danger' red alert for Barcelona warns of more rain on the way - with Spain still reeling from deadly floods

Elsewhere in Spain, search teams continue to scour flooded areas for bodies.

At least 217 people have died after heavy rain in eastern parts caused flash floods that swept away almost everything in their path.

People were trapped in cars, homes and businesses as the waters surged through the disaster zone last week.

Six days later, the search and rescue operation continues for an unknown number of missing people, with thousands of soldiers brought in to help.

And as communities continue to reel from the catastrophic floods - and mourn their losses - more rain is forecast for parts of the country.

Today, the local government in Catalonia has warned of "continuous and torrential" rain in two regions, saying people should avoid travel and stay away from streams and ravines.

A red alert "extreme danger" warning has been issued for Barcelona.

"Do not travel unless strictly necessary," it told people nearby.

Footage on social media shows heavy rainfall overwhelming stairwells and leaving streets strewn with water.

Dozens of flights have been cancelled at El Prat airport after the terminal building was flooded.

Elsewhere in eastern Spain, much attention has been paid to an underground car park in Aldaia, where emergency services have been trying to drain the floodwater to gain access.

There had been fears that dozens of bodies could be found inside the car park after people died while trapped by the rising waters at the Bonaire shopping centre.

However, firefighters have downplayed the situation, Spanish media reported.

"Since yesterday afternoon we were able to get in with canoes, boats, drones and on foot," one of the firefighters told El Pais.

"Yesterday we went through the entire car park and luckily we haven't found any bodies."

They said that could change as the car park empties, but that at the moment the cars are all empty.

There has been anger at the response from authorities and a group of survivors hurled mud and insults at Spain's King Felipe when the monarch visited one of the worst-affected towns.

By the time authorities sent alerts to mobile phones warning of the seriousness of the flooding, and asking people to stay at home, many were already on the road or in places like underground garages that became death traps.

Valencia's MotoGP race, which had been scheduled for later this month, has been cancelled after floods wrought destruction on the track.

Thousands of volunteers have been helping to clear away thick layers of mud from streets and homes.
