Today’s weather will be changeable, with cloud cover and local rain affecting the islands of the Eastern Aegean and the Dodecanese, while isolated thunderstorms are also expected in the Dodecanese, which will quickly subside.

In the rest of the country, the day will start with limited cloud cover, which will increase from midday onwards, bringing local rain, while from the afternoon scattered thunderstorms will develop in the western regions. Snowfall is expected in the mountainous areas of Epirus and Western Macedonia from the evening. Winds will initially be westerly to northwesterly at 4–5 Beaufort, locally up to 6 Beaufort in the south, later turning southerly to southwesterly, reaching locally 7 Beaufort in the Aegean. Temperatures will rise slightly, reaching 15–17°C in the Ionian and mainland areas, while in the northwest they will remain at 12–13°C and in the rest of the islands they will reach 18–19°C.

However, a deterioration of the weather is expected from Wednesday evening. According to the forecast by Giannis Kallianos, during Thursday the weather will worsen further, with rain and thunderstorms across most parts of the country.

As the meteorologist notes, although rainfall will occur across almost the entire country—more widespread and intense in some areas and more local and weak in others—special attention is required in the areas within the highlighted zone, where thunderstorms will also develop at times and may locally be intense.

“I would like to stress that this is a typical winter weather system for January and does not constitute an extreme or unprecedented phenomenon. However, increased readiness is required because there are already areas affected by previous rainfall, as well as regions where high rainfall rates may occur,” he notes.

Why increased caution is required in already burdened areas:

Saturated soils:
Previous rainfall has significantly reduced the soil’s absorption capacity, increasing the risk of surface runoff and local flooding, even with moderate rainfall.

Hydrological fatigue of drainage basins:
Streams, torrents and small waterways now respond faster and more abruptly, with smaller amounts of rainfall sufficient to cause overflows.

Stressed infrastructure:
Road networks, drainage systems and slopes are already under strain, especially in southern parts of Attica, increasing the likelihood of landslides or local accessibility problems.

What to watch out for:

Targeted monitoring in already affected areas, rather than a blanket approach nationwide.
Timely information and operational readiness of local authorities, especially in flood-prone areas.
Avoid complacency, as phenomena may be locally intense even if they are generally considered seasonal.

Finally, during the weekend, weather conditions will once again become unstable across most of the country, with showers, rain and locally thunderstorms.

In summary, these are not extreme events, but weather systems that require increased preparedness, mainly due to existing vulnerabilities. Particular attention should be paid to areas within the highlighted zone (Thursday map), where phenomena may suddenly intensify at a local level.
