The Medicane – meaning Mediterranean hurricane – has similar qualities of hurricanes and typhoons and has already caused flash flooding across Tunisia and Libya over the past few days. Meteorologists are warning that the tropical-like storm is likely to develop features normally associated with a hurricane such as gale-force wings and a fiery eye at its centre. (CNN) People in Greece and Turkey are bracing themselves for a rare and powerful hurricane-type storm in southern Europe's Mediterranean region, due to hit this weekend. The system is expected to move slowly over the island of Crete and southern Greece on Saturday before picking up speed and heading into western Turkey on Sunday. Some parts of the island of Sicily and Greece could see three inches of rain, reported Weather.com. The Medicane will likely get absorbed into the upper-level jet stream and will not linger over southeastern Europe, which will limit the amount of flooding from the storm. Source: @meteociel

According to a study published in 2011 , only about 1-2 "Medicanes" occur per year. These powerful storms usually happen during the months of September and October, when sea surface temperatures in the Mediterranean are still quite warm, although they can occur at any time of year.
