Wind slabs and weakly bonded old snow are to be critically assessed.

The fresh and somewhat older wind slabs can in some cases be released easily. In addition the hard wind slabs are capable of being triggered. The prevalence of the avalanche prone locations will increase at high altitude and in the high Alpine regions.
In some places avalanches can be triggered in the faceted old snow and reach large size in some cases. This applies in particular above the tree line.
At low and intermediate altitudes individual gliding avalanches are possible. In steep terrain there is a danger of falling on the hard snow surface. Restraint is recommended.

Snowpack

dp.6: cold, loose snow and wind
dp.8: surface hoar blanketed with snow

In some regions up to 10 cm of snow will fall. As a consequence of a sometimes strong wind from southwesterly directions, sometimes easily released wind slabs will form. Various wind slab layers are lying on soft layers. Places where surface hoar has been covered with snow are especially precarious. Towards its base, the snowpack is well consolidated.

Tendency

Fresh wind slabs are to be evaluated with care and prudence.
