Piercing cold and snowfall are expected particularly in mainland and Northern Greece on Wednesday. The use of snow chains is required in several parts of the road network. Thick snow is falling on Pelion Mountain and the Pindus mountain range. Due to strong winds, no ships are leaving Rafina and Lavrio ports, while Piraeus port is regularly serviced. After the recent rainfalls, a state of emergency has been declared on Lesvos and Zakynthos islands. The Hellenic National Meteorological Service (HNMS) expects gradual improvement from the evening.
