This footage by IMDLEO.GR shows a sudden storm on December 1st 2022 near the monastery Dionysios on Mount Athos. You see the water storage tank that prevents the plaza from flooding and protects the shoreline from the swirling water and floating forest logs. The river has almost overflowed in places, but the built waterworks have proven their worth. The storm was part of a low-pressure area called Ariel, which brought many downpours and thunderstorms in parts of Greece.
