Civil Protection places 7 regions in RED Code

The General Secretariat for Civil Protection has placed the following areas on “Red Code” mobilization status from midday today, Tuesday, October 13, 2026, through Wednesday, October 14, 2026:

1. The Regional Unit of Evia (Region of Central Greece)

3. The Region of Attica
4. The Region of the South Aegean
5. The Region of Crete
6. The Regional Units of Samos and Ikaria (Region of the North Aegean)

This decision follows the Special Bulletin on Dangerous Weather Phenomena issued today, Tuesday, by the Hellenic National Meteorological Service, and the recommendation of the Committee for the Assessment of Risks Arising from Weather Phenomena and All Types of Civil Protection Risks (under the Ministry of Climate Crisis and Civil Protection).

These assessments indicate a high risk of flooding and very gale-force winds in the aforementioned areas.

Under the mobilization status (Red Code), the National Mechanism is fully mobilized, deploying the necessary personnel and resources—including materials and equipment tailored to specific needs—to ensure readiness against an imminent threat, to address emergencies, and to manage the aftermath of a catastrophic event; simultaneously, short-term recovery, relief, and support actions are initiated to mitigate the disaster’s impact.
