Snowpack Structure

Dry wind-blown snow in the form of slabs and pillows can be found only at the highest altitudes of the Tatras. The snow is very unevenly distributed, some places are blown down to the hard, icy old snow base. On others, on the contrary, a larger amount of snow is blown by the wind. At lower and middle altitudes, the snow will soften, become mushy and lose its cohesion as it warms. In the afternoon, the snow will be soaked throughout the profile.

Tendency

Slightly rising during the day.

Avalanche Activity

Avalanche danger is concentrated in the highest altitudes of the Tatras, where less stable snow slabs and pillows are formed by wind. Dangerous places are located on leeward slopes, troughs and moguls, mostly with south to east orientation. Medium-sized avalanches can be released in such places, mainly after a large additional load. Caution is required in places where old packed snow alternates with wind-blown snow deposits in the form of slabs and pillows. The zero isotherm will rise to 2000 m a.s.l. during the day. An influx of warm air will cause waterlogging and a reduction in snow stability, especially at middle altitudes (up to 1800 m a.s.l.). Minor avalanches and avalanches from wet snow are expected, possibly even medium-sized wet avalanches.
