Cyclone Ianos, also known as Medicane Ianos, was a rare Mediterranean tropical-like cyclone (medicane), that impacted Greece on 17 and 18 September 2020. Ianos developed from an area of low pressure over the Gulf of Sidra that quickly began tropical cyclogenesis while moving over warm waters. After receiving various names from different meteorological centers, the storm, dubbed Ianos by the Greeks, rapidly intensified while moving northeast.
