Turbulent days lie ahead for Greece and Turkey. A low-pressure system over the eastern Mediterranean is causing a significant risk of severe weather.

As early as Tuesday, severe thunderstorms accompanied by heavy rain and gusts of wind will develop from Crete and the Peloponnese, passing through Athens and reaching as far as western Turkey.

The situation is also set to become particularly dangerous, with a risk of flooding, in the region around Istanbul. More than 250 mm of rain could fall there by the weekend. In the Aegean Sea and along the coasts, conditions will also become very stormy, with gusts of up to 65 mph.

On Wednesday, the area of bad weather will spread. The Turkish Mediterranean coast and Cyprus will be affected.
