Winter scenes of deep snow covering the town of Troyan, Northern Bulgaria (red marker on the map) where the snow cover reached about 50 cm. The most affected area in Southern Bulgaria is denoted with the red oval; in some parts in the mountain the new snow cover was more than 1 m in height. Heavy wet snow damaged power lines, closed roads and blocked the access to many parts of the region. A sate of emergency was declared.
