(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.
'Medicane,' a rare, hurricane-like storm, is on track to hit Europe
The storm, often called a "Medicane" (Mediterranean + hurricane) has features similar to hurricanes and typhoons.
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.
The current storm, called Zorba, triggered flash flooding across Tunisia and Libya over the past few days before moving north over the Mediterranean towards Europe.
Over the sea, the storm is likely to pick up more tropical-like features normally associated with hurricanes, such as gale-force winds and even an eye in its center.
The area currently most under threat are the Ionian islands on Greece's western coast where the Hellenic National Meterological Office has put out a severe warning.
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.
On Crete and other southern islands of Greece, as much as 4 to 6 inches (100 to 150 millimeters) of rain could fall, which could lead to flash flooding. Cities like Izmir, Turkey, and Kalamata, Greece, could see 2 to 3 inches (50 to 60 milllimeters).
