The 2013 Sardinia floods took place in and around the Sardinian town of Olbia between 17 and 19 November 2013. They also affected other parts of northeastern Sardinia and killed at least 18 people. Thousands of people were left homeless. The places which suffered the most damage were Olbia, and in general the whole region of Gallura. The flood caused damages of over 1 billion euro.
The flooding was associated with an extratropical cyclone in the western Mediterranean Basin in November 2013, named Cyclone Cleopatra which developed slow-moving embedded thunderstorm complexes, as cold air flowing from the north entered the Mediterranean and interacted with warm moist air to the east.
