Watch the course of the bad weather live:
According to meteo.gr/National Observatory of Athens, the main reason for this change in weather is the change in the atmospheric circulation over Europe as well as the position of the air current (purple shades in Figure 1) over the Mediterranean which has contributed in the development of a barometric low over the area of Italy (Figure 1). We remind you that the air current is a strong current of air at a height of about 10-11 kilometers from the surface of the earth with a basic movement from west to east and its movement determines the creation and movement of barometric systems. The east-southeast movement of the barometric low from the area of Italy towards the Southern Balkans and our country during Monday 09/09 will result in a gradual change of weather from the west of our country with rain and storms.
