The new emergency weather bulletin predicts a worsening of weather conditions starting this afternoon and lasting for almost 24 hours due to the Cassandra storm, which will pass north of Greece but not significantly affect the country, according to the Hellenic National Meteorological Service (HNMS).

A stormy weather system dubbed Cassandra is expected to make an appearance in Greece on Friday, after hitting northern Italy and parts of the Western Balkans.

Storm Atena struck Attica with heavy rainfall beginning in the western regions and gradually spreading across the area, leading to traffic disruptions and power outages in various neighborhoods, including Psychiko, Filothei, Polygon, Lamprini, and Kypseli.

A warning message from “112” was sent shortly after 5 p.m. to residents of Eastern Macedonia, Thrace, Thassos, Samothrace, Lemnos and Agios Efstratios for dangerous weather phenomena expected to “strike” from early Tuesday evening.
