A new worsening of the weather is expected in Greece today, Tuesday, with locally heavy rain, thunderstorms, gale-force winds, and possibly hail.

On Tuesday morning, meteorologist Giorgos Tsatrafyllias posted a warning urging residents of eight regions to be particularly cautious.

“Over the next 24 hours, special caution is recommended due to expected heavy rainfall that may cause:
