As Storm Gloria whips the Mediterranean into a frenzy one small Spanish town has been flooded by salty, white foam.

Tossa De Mar, which is just north of Barcelona, witnessed the power of the deadly storm that has caused chaos throughout Spain and the Balearics.

Video of the frothy sea foam shows streets swamped by the murky mass, in places as high as door frames.

Filmed by Silvia Ragolta Soms, and publishd on the Spanish-language Twitter acount of Reuters, the street is empty apart from two other brave bystanders.

Though spectacular, this effect of the storm is harmless when compared the widespread flooding and winds elsewhere in the country.

Gloria has claimed the life of seven people and left 200,000 without electricity.

Bridges and roads are blocked and have collapsed in heavy flooding.

On Wednesday local authorities said a further three people had died across southeastern Spain.

A man was drowned near the Valencian town of Callosa, while two more people had been killed by falling buildings in the town of Alcoy and Nijar, according to Associated Press reports.

Searches continue for other missing people.

Since Sunday, Spain and the islands of Mallorca and Menorca have encountered hail, blizzards and massive waves.

Record waves of over 9 metres have broken over buildings in Mallorca and Valencia. One clip shows a wave reaching the top of aparment bocks, estimated at 15 metres high.

While the worst of the storm is thought to have passed, popular tourist destinations along the East coast of Spain have suffered a number of indignities.

In Barcelona the city's pleasure beaches have been denuded of sand, leaving them unrecognisable.

La Barceloneta, Barcelona's artificially bathing strand was widened for the 1992 Olympics, was hit by huge waves. Extreme weather patterns have eroded a quarter of the beache's surface area since 2010, which will only be sped up by Gloria.

Rubén del Campo, a spokesman for national weather service AEMET told the Associated Press that the storm is forecast to be one of the strongest on record, with the heaviest rainfall in 70 years.
