Atmospheric rivers (ARs) have emerged as a global relevant driver for extreme hydrometeorological events and water budget modulator in many areas of the globe. Defined as narrow corridors of enhanced horizontal transport of moisture, ARs transfer huge amounts of water vapour from the tropics to the mid-latitudes. Low-latitude moisture export can be important for extreme events at
higher latitudes because it may cause critical precipitation thresholds for flooding to be exceeded. ARs have been studied in the last 20 years along the Pacific US Coast, being responsible for heavy precipitation originated by the interaction -up lift- with the coastal
orography. In the last decade, emerging regions such as Europe have been explored, where ARs have been connected to extreme events, especially those areas facing the Atlantic coast. The detection and investigation of ARs in the Mediterranean basin have started only in the very last years, so that the knowledge on this phenomenon is scarse. Only few studies showed the relevant role of
an AR in severe hydrometeorological events affecting the Mediterranean coast of Spain or the Italian peninsula.
