The country is under a state of heightened alert due to the hazy weather Erminio, with seven regions put on “red” alert and severe phenomena affecting especially Attica, Thessaly, Central Greece and the southern Aegean. At the same time, it was decided to keep schools closed in areas expected to be most affected by heavy rainfall and gusty winds.

Two storm waves in Attica

According to meteorologist Thodoris Kolydas, two successive bouts of bad weather are expected in Attica during the day.

The first phase is forecast to occur in the early morning hours, around 08:00 to 10:00, with gradual strengthening through midday.

The second and most intense surge is expected from the afternoon to evening, approximately between 15:00 and 21:00, with the highest intensities occurring towards the end of the period.

As he explains, the precipitation systems move according to the wind flow at 700 hPa, which means that clouds and showers will be organised from south to north, affecting the regions differently in terms of intensity and duration.

Red alert in seven regions

A state of heightened alert is set:

Central Greece
Thessaly (including Sporades)
Peloponnese
(including the region of Greece).
South Aegean
Imathia
Pieria
central Macedonia

Attica is once again at the center of the bad weather, with the phenomena being characterized as particularly intense and long-lasting.
