Cyclone Numa
Cyclone Numa, also known as Medicane Numa, was a Mediterranean tropical-like cyclone with the properties of a subtropical cyclone. Numa formed on 11 November 2017 west of the British Isles, out of the extratropical remnants of Tropical Storm Rina, the seventeenth named storm of the 2017 Atlantic hurricane season. Subsequently, on 17 November, Numa acquired subtropical characteristics before reaching peak intensity on 18 November, becoming a rare "medicane". After making landfall in Greece on 18 November, Numa rapidly weakened, and was later absorbed into another extratropical storm on 20 November. The flooding triggered by Numa became the worst weather event Greece had experienced since 1977, and the storm caused an estimated $100 million (2017 USD) in damages in Europe.
