A sharp deterioration in weather conditions, marked by an intense cold wave and powerful northerly winds, has put Greek authorities on high alert. The adverse conditions are expected to affect even low-lying areas, particularly in northern Greece, where snowfall is forecast.

The General Secretariat for Civil Protection has issued a public advisory urging citizens to exercise heightened caution and take preventive measures to protect themselves from risks associated with severe weather. Relevant state agencies, along with regional and municipal authorities across the country, have been instructed to remain on increased readiness to respond swiftly to any impacts.

Residents in areas expecting heavy rainfall, thunderstorms or gale-force winds are advised to secure loose objects that could cause damage or injury, ensure gutters and drains are clear, and avoid crossing streams or flood-prone roads—on foot or by vehicle—during storms and for several hours afterward.

Outdoor work and activities in coastal or marine areas should be postponed, as lightning poses a serious threat.

During hailstorms, people are urged to seek immediate shelter in buildings or vehicles and remain there until conditions fully subside. Caution is also advised near large trees, hanging signs, balconies and other structures from which objects may fall. Citizens should strictly follow instructions issued by local authorities, including traffic police.

In regions facing snowfall and frost, drivers are encouraged to check weather forecasts and road conditions before traveling, carry snow chains, keep fuel tanks full, and, if travel is unavoidable, prefer daytime journeys on main roads. Informing family members of planned routes and adjusting travel schedules to avoid peak weather conditions is strongly recommended.

Pedestrians should wear layered clothing and appropriate footwear to reduce the risk of slipping, and avoid unnecessary movement during periods of intense snowfall or icy conditions.
