New snow
2000m
Old wind slabs require caution. New snow as the day progresses.
The somewhat older wind slabs can still be released in some cases in particular on very steep shady slopes and at high altitudes and in high Alpine regions. This applies in particular at their margins. The sometimes deep wind slabs are poorly bonded with the old snowpack. The avalanche prone locations are to be found adjacent to ridgelines and in gullies and bowls. In particular in areas where the snow cover is rather shallow the avalanches can be triggered in the faceted old snow and reach medium size.
As a consequence of new snow and wind more frequent dry snow slides and avalanches are possible as the day progresses, but they will be mostly small. The new snow will be deposited on the quite favourable surface of an old snowpack in all aspects above approximately 2000 m.
In addition by the early morning at low and intermediate altitudes, individual small moist snow slides and avalanches are possible. Backcountry touring and other off-piste activities call for meticulous route selection. The avalanche prone locations are barely recognisable because of the poor visibility.

Snowpack
>
The avalanche conditions above the tree line are to some extent treacherous. The somewhat older wind slabs are lying on weak layers on wind-protected shady slopes and at intermediate and high altitudes. Released avalanches and field observations confirm the unfavourable bonding of the snowpack in particular at the base of rock walls and behind abrupt changes in terrain. During the day: Over a wide area 5 to 10 cm of snow, and even more in some localities, will fall until the afternoon above approximately 2000 m. The wind will be light to moderate adjacent to ridgelines. The northeasterly wind will transport the new snow.
Above approximately 2000 m there are 100 to 200 cm of snow. At high altitudes and in high Alpine regions snow depths vary greatly, depending on the infuence of the wind.

Tendency
Friday: Significant decrease in danger of moist avalanches as the temperature drops. Significant increase in danger of dry avalanches as a consequence of the snowfall. In particular very steep shady slopes and transitions from a shallow to a deep snowpack: Weak layers in the old snowpack necessitate caution.
