Greece will be under the grip of successive bad weather systems with dangerous rainfall and thunderstorms in the coming days. The National Meteorological Service and Klearchos Marousakis warn of dangerous phenomena that will mainly affect the western and northern regions.

The bad weather will start affecting the west of the country from Friday and Saturday, with heavy rainfall and thunderstorms, which will gradually extend to the rest of the regions, while the eastern Aegean is expected to be struck by intense rain. The low pressure system that will form in Italy will not move quickly, due to the presence of an “atmospheric mountain” in northern Europe. This will force the system to remain stationary, intensifying rainfall, mainly in the western and northern parts of the country.

Risks of flooding and damage

Citizens are urged to be particularly careful, as the phenomena will be dangerous, with increased risks of flooding and destruction in areas with poor infrastructure or those already affected by previous weather events. According to the forecast by Klearchos Marousakis, the country will continue to remain in emergency status for several days, with the weekend being the most dangerous period, as the bad weather will spread to eastern Greece and the Aegean.

According to the latest forecast data from the National Observatory of Athens / meteo.gr, on Thursday 06/11 local rain and thunderstorms are expected in the east and south. In the northern parts of Crete, the phenomena will be long-lasting and intense, with emphasis on the regional units of Chania and Rethymno.

Significant rainfall amounts yesterday in the east and south

Rainfall amounts were high yesterday around northern Evia, Magnesia and the Sporades, while the intensity was stronger in the south Aegean where we had thunderstorms, according to meteorologist Thodoris Kolydas, who based on Meteo/EAA measurements up to 6pm Wednesday lists the areas with the highest rainfall:

Skiathos – 95.8mm
Steni Evias – 88.6mm
Kymi – 88.2mm
Skiathos – 57.4mm
Psachna Evias 52.6mm
Skopelos – Glossa 51.0mm

Locally significant rainfall amounts occurred in the morning hours of Wednesday 05/11 mainly in parts of the eastern and southern country. According to the weather station network of the National Observatory of Athens/meteo.gr the highest rainfall up to 10:40 Wednesday 05/11 was recorded at the Skiathos station with 61.6mm.
