A rare tropical cyclone-like storm dubbed medicane formed in the Ionian sea on November 17, 2017, and is affecting the region with heavy rain and strong winds. This strengthening storm is expected to hit the western coast of Greece on Saturday, November 18 or early November 19. This is the second medicane to form this year and the second within the past 20 days.
