Consecutive 112 alerts across Greece
Since yesterday morning, multiple 112 alerts were sent to many regions of the country: East Mani, Evrotas, Pieria, Attica, Central Macedonia, Magnesia, Larissa, Sporades, Evia, Chios, Samos, Ikaria, Dodecanese, Crete, and the Cyclades. They warned of severe weather phenomena and urged residents to avoid unnecessary movement. After midnight, a message was also sent to the residents of Pylos, advising them to limit their travel to what is strictly necessary.

Mayor of Mandra: “The same roads that flooded in the 2017 tragedy have risen again”

Difficult night in Crete
During the night, the skies “opened,” with continuous rainfall, storms, and intense lightning activity. The passage of the severe weather system caused minor problems in Tsoutsouras and Steironas. In Tsoutsouras, strong winds and continuous rain led to fallen trees, while some homes were damaged, with winds removing corrugated roofing from houses. Mud and water accumulated, mobilizing the authorities. Crews were immediately dispatched to repair damage and clear the roads.

Travel extremely difficult on the flooded streets of Nea Peramos
Roads in Nea Peramos are filled with water.

Tram Line 7 operating only on Zephyros – Agia Triada Piraeus section
According to a STASY announcement, the Asklipieio Voulas – Loutra Alimou section is temporarily out of service due to water accumulation on the tramway between the old Town Hall and Glyfada beach, as well as issues with an EYDAP manhole at Agios Kosmas.
