Avalanche Activity

In the Western Tatras, especially on the northern exposures there is an CONSIDERABLE avalanche danger, level 3. Avalanche release is possible with a small additional load. There is a critical layer of square-grained snow underneath the newer overlying snow, which prevents the stabilization of the overlying layers. Occasionally, smaller to medium-sized spontaneous avalanches may occur on very steep slopes.

Snowpack Structure

In the northern sector and at the highest elevations, there are unstable layers of snow in the snowpack. The snow from the last snowfall (after cooling since Sunday), with a total of 15-25 cm, is dry, wind blown and unevenly distributed. At middle and lower elevations the snow is loose, lying on hard ground. On the ridges, overhangs have formed. The snow cover remains well below average, especially at altitudes below 1600 m above sea level.
