Greece is grappling with the severe impact of Storm Adel, which has triggered a “red code” alert—the country’s highest warning level—in four regions.
Since the early hours of Friday, the powerful system has battered Athens with non-stop rain, thunderstorms, and lightning, leading to dangerous street flooding that hampered traffic and threatened both drivers and pedestrians.
The rainfall was categorized as a Category 4 event, signifying “very significant” severity, with warnings issued for the high probability of large hail across Attica.
This was the scene in Varkiza, southern Athens, on Friday morning:
The volatile weather is moving across the nation. Intense rainfall and thunderstorms began on Tuesday across Western and Northwestern Greece. While storms are already active in Eastern Macedonia and Thrace, they are slated to reach Thessaloniki and Halkidiki later.
Forecasters predict a “double wave” of severe weather for Attica, with the Eastern Aegean (including Chios, Samos, and Ikaria) and the Dodecanese bracing for the brunt of the system from midday onward.
Civil Protection and emergency centers are coordinating closely as regions like the Ionian Islands, Peloponnese, and Central Macedonia remain on heightened standby for a rapid response.
