Rain and storms lasting until early morning hours, strong local northern winds, and a drop in temperature are the main weather features today. According to meteorological forecasts, the weather change that has affected the country since yesterday afternoon has significantly helped to clear out African dust, and conditions are expected to improve in most regions by midday.

However, the severe weather that hit the country yesterday caused several issues in Crete, Lamia, and Attica.

Due to heavy rainfall late Sunday night, Koropi Avenue in Markopoulo became impassable, with many cars stranded and drivers calling the Fire Department.

Around midnight, continuous rain caused flooding in several areas. The fire department received at least 17 calls to pump water in northeastern Attica, especially in the municipalities of Marathon, Rafina, Pikermi, and Penteli.

According to Meteo, rainfall occurred late Sunday in Agia Paraskevi, Pallini, Papagou, Marousi, Kantza, Vyronas, Spata, Nea Makri, Penteli, Rafina, Koropi, Gerakas, and Markopoulo.

Rain was also recorded in Naxos, Skyros, Ikaria, parts of Evia, Boeotia, Chalkidiki, Thasos, Drama, and Alexandroupolis.

Heavy rain hit the city of Lamia, and strong winds brought down numerous trees, even within the city. Power outages occurred in the southern part of Lamia, leaving hundreds of households without electricity for more than two hours.

The fire department received many calls to pump water, especially from southern neighborhoods, while the Traffic Police restricted access to streams that had dangerously overflowed and were impassable for cars and people.

Problems in Crete

In Crete, strong southern winds caused significant damage, toppling trees, DEI poles, and even a football goalpost. The winds also affected flights at the Heraklion and Chania airports, causing passenger disruptions.

Kissamos Municipal Stadium did not escape the strong winds either. The Kastelli stadium, exposed by the sea, sustained infrastructure damage, including a collapsed goalpost and a high jump mat blown dozens of meters away.

More than ten aircraft could not land at Heraklion Airport on Sunday. In Chania, a flight from Frankfurt was diverted to Athens and finally arrived with a four-hour delay. Delays were also observed for other arriving flights.
