Greece – Flash Floods in Halkidiki After Heavy Rain From “Storm Medusa”

A severe weather system, named “Medusa” by local media, brought heavy rain to parts of the Halkidiki (also known as Chalkidiki) Peninsula in Greece on 16 July, causing flash floods.

Halkidiki is in the Region of Central Macedonia in Northern Greece and is a popular tourist destination. Local media said that the worst hit area was Toroni in Sithonia (also known as Longos), where flood water swept through streets and dragged away cars and camping trailers. At least 9 people had to be rescued. Several roads were blocked by flood debris and rock slides. Buildings, including hotels, were also damaged.
