Greece’s Civil Protection authorities are on heightened alert as severe weather affecting the country has placed several regions under a Red Code warning. Authorities are on standby to deal with potential flooding, while a new meeting of the Risk Assessment Committee has led to the extension of the measures to the Cyclades ahead of the 28 October national anniversary.

Following the committee’s meeting, and based on the updated Emergency Bulletin of Dangerous Weather Phenomena issued by the Hellenic National Meteorological Service (HNMS), the Cyclades regional units in the South Aegean Region have also been placed under Red Code alert for Wednesday, 28 October 2026, owing to the high risk of flooding.
