Two atmospheric disturbances will affect our country in the coming days, causing rain, storms, very strong southerly winds, and snow in the mountains, according to the Director of the Hellenic National Meteorological Service (EMY), Thodoris Kolyda.

As he emphasizes in a post, the first disturbance will occur tonight, and the second one on Friday into Saturday. The areas that will experience the heaviest rainfall this week will be western and northern Greece and the eastern Aegean, with the well-known “P-type” weather, according to Mr. Kolyda.

Kolyda’s detailed post:

Two atmospheric disturbances will affect our country in the coming days, the first from Wednesday to Thursday and the other from Friday to Saturday, causing rain, storms, very strong southerly winds, and snow in the mountains.

The areas that will experience the heaviest rainfall this week will be western and northern Greece and the eastern Aegean, where we will have the well-known “P-type” weather.

It is noted that the expression “P bad weather,” which is frequently used by the media, is incorrect, as “P-type” weather is simply a type of weather caused by a southwest wind at medium atmospheric levels over our country, where orography and the Aegean Sea play a significant role.

Rainfall and possibly sporadic storms will initially occur in the west, gradually affecting the northeastern mainland, the eastern Aegean, the Cyclades, and Crete.
