Six Regional Units of the country are being placed today, Monday January 26, under a “Red Code” state of mobilization due to worsening weather conditions and an increased risk of flooding.

These include the Regional Unit of Serres in Central Macedonia, as well as the Regional Units of Drama, Kavala, Thasos, Xanthi, and Rodopi in the Region of Eastern Macedonia and Thrace.

Severe weather has also caused disruptions to ferry services, as the morning routes of Blue Star Delos and Fast Ferries Andros were canceled, while flying dolphins to the islands of the Saronic Gulf are also docked. In addition, the morning departure from the port of Rafina will not take place.

Civil Protection decision following an Emergency Weather Deterioration Bulletin by the EMY

According to an announcement by the Ministry of Climate Crisis and Civil Protection, the General Secretariat for Civil Protection placed the above areas under “Red Code” status following the issuance of an Emergency Weather Deterioration Bulletin by the Hellenic National Meteorological Service (HNMS) and a meeting of the Risk Assessment Committee.

In this context, municipalities and regions are called upon to immediately convene the Local and Regional Civil Protection Operational Coordination Bodies (T.E.S.O.P.P. and P.E.S.O.P.P.) in order to assess the readiness of mechanisms and measures to address potential flooding phenomena.

Category 3 rainfall event – Locally intense phenomena

According to the available forecast data from the National Observatory of Athens / Meteo.gr, on Monday 26/01 a Category 3 (Significant) rainfall event is expected, with locally heavy rain and thunderstorms.

The deterioration of the weather will begin in the west and gradually expand to:

• Eastern Central Greece,
• Southern and Eastern Peloponnese,
• Evia,
• Central and Eastern Central Greece,
• Crete from the pre-noon hours,
• Cyclades from midday,
• Sporades,
• the islands of the Northern and Eastern Aegean,
• and the Dodecanese.

The phenomena will locally be accompanied by hailstorms, mainly in island areas of the Southern and Eastern Aegean, and possibly in parts of northeastern Peloponnese and southern Attica. At the same time, locally gale-force southerly winds will prevail in the Aegean.

The following maps show the estimated rainfall totals at two time snapshots on Monday 26/01.

Kallianos: “Not alarmism, but heightened alertness in Attica”

In a social media post, meteorologist Giannis Kallianos notes that from midnight until the early morning hours of Monday, weather conditions in Attica will gradually become unstable, with light local rainfall, and no serious problems expected.

However, between 07:00 and 10:00–11:00 in the morning, thunderstorms are expected to pass through the prefecture, which could locally produce increased rainfall totals. He stresses, however, that these phenomena are in no way comparable to last week’s destructive storm in Ano Glyfada.

Special attention to Ano Glyfada, Hymettus, and the Southern Suburbs

Particular reference is made to Ano Glyfada and the Southern Suburbs in general, where debris remains on roads despite cleanup efforts. As Mr. Kallianos notes, even brief but intense rainfall can cause the movement of mud, stones, and soil.

Increased caution is advised:

• on roads with remaining debris,
• in areas near slopes and streams,
• in the wider Hymettus area, where excavation works have reduced the soil’s natural absorbency,
• on downhill roads in the Southern Suburbs,
• and in keeping drains and runoff systems clear.

“No alarmism – Yes to timely prevention”

As the meteorologist emphasizes, this is not an extreme or dangerous phenomenon comparable to the recent flooding event. However, the burden on soil and infrastructure necessitates heightened preparedness.

“Proper management of natural disasters is based on the timely identification of vulnerable points and not on alarmism,” he notes, calling on both citizens and authorities to remain on heightened alert over the coming hours.
