The fresh wind slabs are to be evaluated with care and prudence in steep terrain. As a consequence of new snow and a sometimes strong wind from northerly directions, mostly small wind slabs formed at elevated altitudes. The small quantity of fresh snow as well as the wind slabs to be found above all adjacent to risgelines and in gullies and bowls are lying on the unfavourable surface of an old snowpack on very steep, little used shady slopes above the tree line. In very isolated cases avalanches can be triggered in the faceted old snow and reach medium size. Caution is to be exercised in areas where the snow cover is rather shallow. Apart from the danger of being buried, restraint should be exercised as well in view of the danger of avalanches sweeping people along and giving rise to falls.
Snowpack
dp.6: cold, loose snow and wind dp.4: cold following warm / warm following cold
In some regions 10 to 15 cm of snow has fallen. Since Monday the wind has been strong to storm force over a wide area. The wind will transport the fresh and old snow. The fresh wind slabs are lying on weak layers in particular on very steep shady slopes above the tree line. As a consequence of mild temperatures and solar radiation the snow drift accumulations stabilised. In very isolated cases weak layers exist in the centre of the snowpack. This applies in particular on very steep shady slopes above approximately 2400 m. At elevated altitudes snow depths vary greatly, depending on the infuence of the wind.

The fresh wind slabs are to be evaluated with care and prudence in steep terrain. The avalanche prone locations are to be found on very steep shady slopes above approximately 2400 m and in gullies and bowls, and behind abrupt changes in the terrain. In very isolated cases avalanches can be triggered in the old snow and reach medium size. Caution is to be exercised in areas where the snow cover is rather shallow.

Since Monday the wind has been strong to storm force over a wide area. Some snow will fall. The wind has transported the fresh and old snow. The fresh wind slabs are lying on soft layers in particular on west to north to east facing aspects above approximately 2400 m. The old snowpack will be generally well bonded. In very isolated cases weak layers exist in the centre of the snowpack. This applies in particular on very steep shady slopes above approximately 2400 m. At elevated altitudes snow depths vary greatly, depending on the infuence of the wind. On sunny slopes below approximately 2200 m only a little snow is lying.

On Monday the wind was moderate to strong over a wide area. The wind has transported the fresh and old snow. The fresh wind slabs will be deposited on soft layers in particular on west to north to east facing aspects above the tree line. In very isolated cases weak layers exist in the centre of the snowpack. This applies in particular on very steep shady slopes above approximately 2400 m.

As a consequence of a sometimes strong wind from northerly directions, mostly small wind slabs formed in the last few days at elevated altitudes. These avalanche prone locations are to be found on very steep shady slopes above approximately 2400 m and in gullies and bowls, and behind abrupt changes in the terrain. The fresh wind slabs are to be evaluated with care and prudence in steep terrain. In very isolated cases avalanches can be triggered in the faceted old snow and reach medium size.

Apart from the danger of being buried, restraint should be exercised as well in view of the danger of avalanches sweeping people along and giving rise to falls.
Snowpack
As a consequence of mild temperatures and solar radiation the snowpack settled. For those venturing off piste a low avalanche danger will be encountered over a wide area. Field observations and stability tests have confirmed a widespread favourable avalanche situation. The sometimes strong wind has transported the loosely bonded old snow. The wind slabs are to be evaluated with care and prudence in very steep terrain. In very isolated cases weak layers exist in the centre of the snowpack. This applies in particular on very steep shady slopes above approximately 2400 m. At elevated altitudes snow depths vary greatly, depending on the infuence of the wind. On sunny slopes below approximately 2200 m only a little snow is lying.
