A very autumnal setup is forming on Saturday, Sunday and Monday across much of the country, with heavy rain and thunderstorms mainly in the west. An emergency deterioration bulletin from EMY is in force, while according to meteorologists Theodoros Kolydas, Giorgos Tsatrafilias, Christina Rigou and Christina Souzi, the phenomena will affect almost the entire country, with different intensity from region to region.

The National Meteorological Service has issued an orange warning for the next three days (Saturday 8 to Monday 10 November), warning of severe weather that will strike mainly western Greece. The system bringing the rain and storms originates from the so-called “western moisture front” transporting large amounts of moisture from the Ionian towards the mainland.

More specifically, locally intense phenomena are forecast:

1. Saturday (08–11–25) until afternoon in the Ionian, Epirus, western Sterea and north-western Peloponnese.
2. Sunday (09–11–25) from late morning in the Ionian and from afternoon in western Sterea and Epirus.
3. Monday (10–11–25)
   a. until midday in the Ionian, Epirus and western Sterea
   b. until evening in western Peloponnese
   c. from late morning in central and eastern Macedonia.

According to EMY director Theodoros Kolydas, the next three days have all the characteristics of an intense autumn severe weather event, with locally heavy rains and thunderstorms in western Greece. Most vulnerable areas: Epirus, western Sterea (especially Aitoloakarnania), Ilia and Messinia. Eastern Sterea, the Aegean and Crete will be affected less.

The heaviest rainfall concentration is expected from Corfu and Ioannina down to Patras, Pyrgos and Kalamata, with totals reaching 80–120 mm and possibly exceeding 130 mm in mountainous areas. Kolydas estimates the weather will begin to gradually improve from Tuesday, first in the west and then elsewhere.

Meteorologist Christina Rigou noted storms will occur mainly in the west and north, however there will also be rain in Athens. “It will rain across Attica but they will be light rains,” she clarified — mainly Saturday and Monday — without causing problems.

Meteorologist Christina Souzi forecasts cloudy conditions in Attica with occasional light local showers and temperatures 14–21°C. Local showers are also expected in Thessaloniki with temperatures 10–18°C.

Giorgos Tsatrafilias says rain will occur in Attica Saturday midday which is not expected to cause serious problems.

Areas with intense phenomena

According to Tsatrafilias, the severe weather begins from early Saturday dawn with strong storms in the Ionian, Epirus, Aitoloakarnania and Messinia, then spreading into northern Greece.

“Attention should be paid to the Ionian islands, Epirus, parts of western Sterea as well as areas of the western and southern Peloponnese,” said Christina Rigou.

Sunday afternoon the second wave of severe weather begins again from western Greece affecting the Ionian, Epirus, Aitoloakarnania and Peloponnese — then extending into northern Greece and continuing also on Monday.

On Monday, rain and storms will affect mainly the west, the centre and the north. On Tuesday Tsatrafilias expects rain in Attica, the eastern Aegean and the Dodecanese.
