The weather phenomenon – which gets its name from having hurricane like characteristics and being over the Mediterranean Sea – will bring with it some ferocious weather.
As the area of low pressure drifts up from Libya towards Italy late on Wednesday and then onto Greece on Thursday, the skies will crack open with ferocious thunderstorms.
The medicane will be at its most fearsome when over water, with winds of 60mph forecast to buffet islands in the Mediterranean.
The Hellenic National Meteorological Service has issued an extraordinary weather and gale warning ahead of the storms landing, which has been named Cyclone Ianos.
The Greek Civil Protection Agency warned today: “Material damage may be caused by strong winds and collisions with objects flying in the wind.
“There may be damage to roofs, gutters, windows, but also falls of trees or pillars of PPC.
“Heavy rainfall can cause flash floods in urban areas.
“Flooding may occur in coastal areas due to rising sea levels due to the high barometric pressure created as the cyclone reaches land.
“There may be temporary interruptions in electricity, telecommunications, water supply and sewerage due to faults in the respective networks.”
According to Tyler Roys, AccuWeather Meteorologist, the exact path the storm is going to take is unclear.
“This storm can bring wind gusts of 80-97 km/h (50-60 mph) to southwestern and southern Greece including the island of Crete,” he said.
Winds that speed can down trees and power lines, leading to power outages.
Coastal flooding is also likely along exposed beaches while flash flooding is forecast across the western coast and east-central coast of Greece.
As much as 10cm of rain is expected to fall.
Storm Ianos will begin dissipating through the end of the weekend.
Areas of rain and thunderstorms are expected to linger over southern Greece and western Turkey into next week.
