A dramatic shift in weather conditions we will see over the next few hours. The storm system called Cassilda is known as a medicane (Mediterranean tropical-like cyclone).
According to images Cassilda could impact western Greece on Thursday night into Friday morning. Cassilda will be the first event of the 2020/21 Mediterranean medicane season.
Warm waters of the Mediterranean are an important ingredient for storm systems and convective storms during the autumn months. And so are for the potentially developing medicanes. The higher the sea temperatures, the higher dewpoints and therefore more energy to fuel the storms.
Peak gusts could reach as high as 200km/h
