Wind slabs and weakly bonded old snow require caution.
In isolated cases avalanches can be triggered in the weakly bonded old snow. Such avalanche prone locations are to be found in particular on extremely steep shady slopes above approximately 2400 m.
As a consequence of new snow and a strong wind from southeasterly directions, wind slabs formed on Wednesday in gullies and bowls and behind abrupt changes in the terrain. These can in some cases be released, even by a single winter sport participant, but they will be small in most cases. Caution is to be exercised in particular on shady slopes above the tree line in the regions exposed to heavier precipitation. Avalanches can in isolated cases penetrate deep layers and reach medium size, especially at elevated altitudes.
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
Over a wide area 10 to 30 cm of snow, and even more in some localities, fell yesterday above approximately 1200 m.
The new snow is lying on the unfavourable surface of an old snowpack in particular on shady slopes above approximately 2400 m. Faceted weak layers exist in the bottom section of the snowpack.
The snowpack will be generally subject to considerable local variations. Hardly any snow is lying on south facing slopes. Only a small amount of snow is lying for the time of year in all altitude zones.
Tendency
The conditions will foster a gradual stabilisation of the snow drift accumulations.

As a consequence of new snow and a strong wind from easterly directions, wind slabs formed on Wednesday in gullies and bowls and behind abrupt changes in the terrain. These can in some cases be released, even by a single winter sport participant, but they will be small in most cases. Caution is to be exercised in particular on shady slopes above the tree line in the regions exposed to heavier precipitation.
Snowpack
dp.6: cold, loose snow and wind
In particular along the border with Veneto 5 to 10 cm of snow has fallen. The wind was strong for a temporary period in some regions. The fresh wind slabs are lying on the unfavourable surface of an old snowpack on wind-protected shady slopes. The old snowpack will be subject to considerable local variations.
Tendency
The conditions will foster a rapid stabilisation of the snowpack.

Snowpack
dp.6: cold, loose snow and wind dp.1: deep persistent weak layer
In some regions up to 15 cm of snow has fallen. The wind will be strong for a temporary period in some localities. The fresh wind slabs will be deposited on the unfavourable surface of an old snowpack on wind-protected shady slopes. The old snowpack will be subject to considerable local variations.
Tendency
The conditions will foster a gradual stabilisation of the snow drift accumulations.
Danger level
Individual avalanche prone locations are to be found on shady slopes at elevated altitudes.
As a consequence of new snow and a gusty wind, sometimes avalanche prone wind slabs formed in isolated cases. Caution is to be exercised adjacent to ridgelines and in gullies and bowls at elevated altitudes.
In isolated cases avalanches can be triggered in the weakly bonded old snow. Such avalanche prone locations are to be found in particular on extremely steep shady slopes above approximately 2600 m. Mostly avalanches are small.
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
Shady slopes above approximately 2600 m: Faceted weak layers exist in the bottom section of the snowpack.
Below approximately 2600 m: The snowpack is largely stable. Hardly any snow is lying on south facing slopes.
The snowpack will be generally subject to considerable local variations. Less snow than usual is lying in all altitude zones.
Tendency
Low avalanche danger will prevail.

Some snow has fallen. In some cases new snow and wind slabs are lying on soft layers. The fresh wind slabs are in isolated cases prone to triggering.
