2018 Signs of a 'Medicane' forming near Greece. An unofficial term for a deep cyclone in the Mediterranean. A low pressure bringing gales, heavy rain and high waves, not good holiday weather.
Sept 2018 You could be heading to the Mediterranean at this time of year in search of sunshine and September warmth, with visions of eating outside and a last outing for your summer clothes before the UK winter takes hold. However this week Greece and possibly southern Italy and Malta, Albania and western Turkey are in for some wild weather. Heavy rain and gales whipped up around a deepening area of low pressure.
Low pressures do form over southern European, the Genoan Low is one famous type but this one shows signs of becoming a "Medicane". This is an unoffical term for a low which shows tropical characteristics and can bring violent weather in the Med. They don't occur too often, we talked about one last year.
Warm waters below and cold air aloft
They are quite unusual especially if an eye forms and is visible on the satellite pictures. This can happen. The sea waters are still very warm. The bad weather tends to stick around for many days. Sometimes the system just drifts about slightly but it can result in severe flooding and wind damage. The sustained winds can reach hurricane strength and the seas are wild.
