Orange thunderstorm warnings are in force across northern Greece on June 12: West and Central Macedonia, Epirus, Thessaly and later Thrace are in the path of the storms.
The Hellenic National Meteorological Service activated orange-level warnings starting from the morning of June 12 for West and Central Macedonia, extending to Epirus and Thessaly by mid-morning and reaching Thrace in the evening.
Severe Mediterranean thunderstorms typically bring intense downpours, hail and strong gusts — a particular danger in mountain valleys, where streams rise within minutes.
The warning wave moves west to east through the day, so conditions in each region deteriorate at different hours.
