Fresh wind slabs are to be evaluated with care and prudence. Avalanches can in isolated cases be released in the old snowpack.
As a consequence of new snow and a moderate to strong wind, clearly visible wind slabs formed in gullies and bowls and behind abrupt changes in the terrain. These are mostly rather small but can in some cases be released easily. 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.
On extremely steep sunny slopes small loose snow avalanches are to be expected as a consequence of solar radiation.
Weak layers in the old snowpack can still be released in very isolated cases by winter sport participants in particular in little used terrain. Such avalanche prone locations are to be found in particular on extremely steep shady slopes at high altitudes and in high Alpine regions. Caution is to be exercised at transitions from a shallow to a deep snowpack, when entering gullies and bowls for example. The avalanche prone locations are barely recognisable, even to the trained eye. Avalanches can reach medium size.
Snowpack
dp.6: cold, loose snow and wind dp.1: deep persistent weak layer
Over a wide area 10 to 20 cm of snow has fallen. The wind was strong in some cases. The fresh wind slabs are lying on soft layers at high altitudes and in high Alpine regions. Faceted weak layers exist in the bottom section of the snowpack especially on west, north and east facing slopes. These can only be released in isolated cases.
The solar radiation will give rise as the day progresses to moistening of the snowpack on steep sunny slopes. At elevated altitudes snow depths vary greatly, depending on the infuence of the wind. Only a small amount of snow is lying for the time of year.
Tendency
The weather conditions will facilitate a strengthening of the snow drift accumulations. Weakly bonded old snow requires caution.

A generally favourable avalanche situation will prevail. Fresh wind slabs require caution.
As a consequence of new snow and a sometimes moderate wind, small wind slabs formed adjacent to ridgelines and in pass areas. These are in some cases prone to triggering in particular on very steep shady slopes. Apart from the danger of being buried, restraint should be exercised in particular in view of the danger of avalanches sweeping people along and giving rise to falls.
On extremely steep sunny slopes small loose snow avalanches are to be expected as a consequence of solar radiation, especially in the regions exposed to heavier precipitation.
On steep grassy slopes individual small to medium-sized gliding avalanches are possible. This applies in particular in the west on steep sunny slopes below approximately 2400 m.
Snowpack
dp.6: cold, loose snow and wind dp.2: gliding snow
5 to 15 cm of snow, and even more in some localities, has fallen. The wind was light to moderate. Fresh wind slabs are lying on soft layers on near-ridge shady slopes. Faceted weak layers exist in the bottom section of the snowpack on west, north and east facing slopes. These are unlikely to be released now.

As a consequence of new snow and a sometimes moderate wind from variable directions, small wind slabs formed adjacent to ridgelines and in pass areas. These are in isolated cases prone to triggering in particular on very steep shady slopes. Restraint should be exercised because avalanches can sweep people along and give rise to falls.
