The streets filled with seafoam, a natural but rare occurrence caused by the severe agitation of sea water and is completely harmless.
High winds and rough seas have caused devastation along Spain’s eastern Mediterranean coast, destroying seafront promenades and damaging buildings along them.
According to the Catalan Water Agency the foam occurs when seawater meets fresh water from a stream. The mixture stirred up by the pounding waves, plus the load of organic material in both waters, generates this abundant foam.
Here are a selection of the best images shared of the foam phenomenon in Tossa de Mar.
The foam appeared to be waist-high in some parts of the town.

A Tossa de Mar l'escuma del mar ha arribat fins als carrers més propers al passeig del Mar. La majoria de comerços han hagut de tancar, i ara veïns i bombers intenten treure l'aigua #Gloria pic.twitter.com/zFSRGESAvp
