Greece issues red weather warnings for Thessaly, Evia and the Dodecanese on 28 October

Red warnings for four areas

The national weather service (EMY) has issued an updated emergency bulletin on dangerous weather, which revises the one issued on Monday, 26 October 2026 under reference 8/2026. For Wednesday, 28 October, heavy rain and storms are forecast across several areas of the eastern part of the country, possibly with local hail. The most intense phenomena, under red warnings, are expected in Thessaly, the Sporades, Evia and the Dodecanese. The Thessaly warning covers the Magnesia and Larissa regional units, and the Sporades and Evia warnings run until late at night. Orange warnings apply to the islands of the eastern Aegean until late in the evening, and to eastern Sterea, mainly Phocis, Phthiotis and Boeotia, at times until late at night.

Civil Protection calls for limited travel

On Tuesday, 27 October, Civil Protection sent 112 alerts to residents of Magnesia and the Sporades, and the same message also went to Evia. The alert asks people to cut their travel to what is essential, to stay on heightened alert and to follow the instructions of the competent authorities. The Evia text, issued through the 112 system, reads:

“Rain and storms, locally heavy, will occur in the Evia regional unit throughout Wednesday 28/10. Limit your movements to the absolutely necessary.”

The Evia message was sent on the afternoon of Tuesday, 27 October, and was addressed to all citizens there.

Red Code mobilisation until 29 October

A Red Code mobilisation status has been in place since Monday, 26 October, for the Evia, Phthiotis and Boeotia regional units of Central Greece, the Sporades, Magnesia and Larissa regional units of Thessaly, the Attica region, the Dodecanese and the North Aegean region. That status runs until and including Thursday, 29 October 2026. According to scientists of the Risk Assessment Committee, rain and storms are expected mainly in the central and southern country, locally strong on 28 October in Evia, Magnesia, the Sporades, the Dodecanese, Larissa, Skyros, Phthiotis, Boeotia, Attica, the Cyclades and the eastern Aegean.

Timing and what comes next

The storms are forecast for Wednesday, 28 October, the day of the national anniversary, and the 112 messages to Magnesia and the Sporades framed the whole day as affected, since the bad weather is expected to last throughout it. The EMY bulletin states that it is being updated in line with the latest forecast data. The Red Code mobilisation status covers the listed regions until Thursday, 29 October. No outcomes have been reported yet, and the warnings are the only official information in the source reports.
