Meteorological history
A first outlook about the possible development of a shallow warm-core cyclone in the Mediterranean was issued by ESTOFEX on 25 September 2018, and a second extended outlook was issued on 26 September 2018. On 27 September 2018, an extratropical storm developed in the eastern Mediterranean Sea. Water temperatures of around 27 °C (81 °F) supported the storm's transition into a hybrid cyclone, with a warm thermal core in the center. The storm moved northeastward toward Greece, gradually intensifying and developing characteristics of a tropical cyclone. On September 29, the storm made landfall at peak intensity in the Peloponnese, west of Kalamata, where a minimum central pressure of 989.3 mbar (29.21 inHg) was reported. ESTOFEX reported on Zorbas as "Mediterranean Cyclone 2018M02", with the same pressure of 989 mbar (29.2 inHg) at Kalamata, further estimating the minimum central pressure of the cyclone to be 987 mbar (29.1 inHg), with one-minute maximum sustained winds of 120 km/h (75 mph) and a Dvorak number of T4.0, which all translate into marginal Category 1 hurricane characteristics for the cyclone. Early on 1 October, Zorbas emerged into the Aegean Sea, while accelerating northeastward. On 2 October, Zorbas moved over northwestern Turkey and dissipated. A cold wake was observed in the Mediterranean Sea, with sea surface temperatures dropping 3–4 °C (5–7 °F) along the track of Zorbas due to strong upwelling.
It is unknown who named the system Zorbas, but the name is officially recognized for a medicane by the Deutscher Wetterdienst.
