low-pressure system “Ballos” has reached Greece.
The phenomena includes hail on the islands and coastal regions and snow at high altitudes, gale-force winds at sea reaching up to 8 or 9 Beaufort on Friday, with strong gusts accompanying the storms.
Temperatures are forecast to drop significantly, especially on the mainland.
The stormy weather reached Athens in the early hours of Thursday, bringing thunder, lightning and showers, and causing fluctuations in the power supply, as well as some flooding in West Attica.
In an emergency bulletin on Wednesday, meanwhile, EMY warned of gale-force winds at sea, which are expected to reach speeds as high as 9 Beaufort in the southern Aegean by Friday.It also said that Ballos will be pushing temperatures down to more seasonal levels across the country, possibly bringing snow to the highlands of Epirus and Macedonia.
The climate crisis and civil protection ministry has advised residents in the areas expected to be badly affected to exercise great caution and avoid unnecessary travel, to securely fasten doors and windows and be ready to move to higher parts of the house in the case of flash flooding and torrents.
In areas that have flooded before, it has advised against remaining in basement or underground areas and warned that people must not attempt to cross flooded roads or streams and torrents, either on foot or in a vehicle, for any reason.
Authorities also advise the securing of loose objects that may be washed or blown away and cause either damage or injury, as well as ensuring that drains and guttering are not blocked and are working properly.
People are also advised to take cover immediately in the case of hail and to protect animals, if possible, and to avoid passing under big trees, signs and places where objects may fall from above.
