Avalanche Activity

New wind-blown snow on hard ground

Moderate avalanche danger, level 2, is concentrated above the forest boundary where 15cm of new snow has fallen, which is getting heavier due to warming. Above 1700m above sea level, due to strong winds, unstable snow slabs and pillows are forming, especially in the northern orientations. The slabs and the new snow are deposited on the old hard base, which is not sufficiently well bonded with it. The avalanche can be released locally even with a small additional load. Smaller spontaneous avalanches may also occur due to warming.

Snowpack Structure

The older snow cover is mostly well consolidated and settled. Up to 15cm of new snow has fallen on it. It is unevenly distributed, especially in the northern sector. Hard slabs alternate with puffy pillows of new snow. Isotherm zero is around 1700m above sea level. Below this threshold the snow is wet and heavy.
