Greece is bracing for a second severe weather system following a storm expected this weekend, with meteorologists warning that the next front could be even more intense.
According to weather expert Klearchos Marousakis, a low-pressure system forming over Italy will move toward Greece from midweek, bringing heavy rainfall and potential flooding to large parts of the country, including the capital, Athens. The event is expected to last two to three days.

Strong rain and thunderstorms are expected from Saturday evening (September 27) through Sunday night (September 28) across the Ionian Islands—such as Zakynthos, Kefalonia, Ithaca, and Lefkada—as well as western regions including Aetolia-Acarnania, and the western Peloponnese provinces of Achaea, Ilia, and Messenia.
