Avalanche Activity

Beware of inflated snow boards and pillows! They are very susceptible to slides and avalanche release when loaded.

In the High, West and Low Tatras there is a moderate avalanche danger above the forest line, 2nd degree. Snow from the last snowfall was blown by strong winds to the leeward slopes. It has created unstable snow pillows and slab snow, which can cause avalanches on steep slopes when mechanically loaded. Inside the snow cover there is a layer of square-grained snow, which manifests itself in the typical warning signals of cracking of the snow cover and rumbling -grey sounds. Larger spontaneous avalanches are not expected.

Snowpack Structure

In the northern sector and at the highest elevations, there are unstable layers of snow in the snowpack. Snow from the last snowfall (10 to 20 cm) fell during the advancing Arctic air, changing from wet to moist, gradually to dry, wind-blown snow. It is unevenly distributed, especially in the northern sector. Hard slabs alternate with puffy pillows of new snow. On the ridges, drifts have formed. The snow cover remains well below average, especially at altitudes below 1600 m above sea level.
