Cyclone “Eva”: pthe weather changes from friday
Generally clear weather with scattered clouds in the west and north. From the second half of the day, the clouds in the northwest will become denser, local showers will pass, which will intensify during the night.

The temperature will not change significantly.

Downpours on Sunday
Across the country increased cloudiness with showers and occasional severe thunderstorms in the west, north and possibly center. In the evening, the phenomena in the west will weaken.

Why November is considered a weather-dangerous month in Greece

If we turn to books on climatology and meteorology, we will see that November is represented as statistically most dangerous month in terms of weather events. The simple explanation we could give is that the atmospheric circulation is starting to change, and colder air masses are descending from the north further south. But the journey of these colder gaseous masses is not easy, as they also interact with the Earth’s surface. So on their way they will meet seas, lakes and oceans, and it is here that one of the foundations of this phenomenon is hidden. The reason is that areas with a lot of water (seas, oceans, rivers, large reservoirs) heat up and cool down more slowly than land. In this case, they have retained heat from the hot days of the previous summer months, and because of this, there are areas of low pressure above them.
When colliding with cold air masses moving from the north (since the land cools much faster), active weather phenomena occur that can turn into cyclones and tropical storms.
