A gradual deterioration of the weather is expected from today through the coming Monday. The intense cold wave, named “Coral,” will impact both Greece and the broader region of Southeastern Europe.

Temperatures will gradually drop by 8 to 10 degrees Celsius in Northern and Eastern Greece, with the lowest temperatures expected over the weekend.

Gale-force northerly winds will dominate the Aegean, reaching 7 and locally up to 8 on the Beaufort scale. At the same time, two disturbances will bring snowfall, mainly affecting northern, central, and eastern mainland regions, as well as the Aegean islands and Crete.
