Weakly bonded old snow requires caution. Fresh wind slabs at elevated altitudes.
Shady slopes: Avalanches can in some places be released by a single winter sport participant. The avalanche prone locations are to be found in particular on little used slopes above approximately 2200 m and in gullies and bowls, and behind abrupt changes in the terrain. The number and size of avalanche prone locations will increase with altitude. Individual avalanche prone locations are to be found also on sunny slopes in high Alpine regions. Avalanches can in some cases release deeper layers of the snowpack and reach quite a large size.
Sunny slopes: As a consequence of warming during the day and the solar radiation, the likelihood of moist loose snow slides being released will increase a little.

The new snow and wind slabs of the last few days are lying on the unfavourable surface of an old snowpack in particular on shady slopes at elevated altitudes. Avalanche prone weak layers exist in the old snowpack especially on little used shady slopes.
The solar radiation will give rise as the day progresses to increasing moistening of the snowpack on steep sunny slopes.
Tendency
The weather conditions will facilitate a stabilisation of the snowpack. Wind slabs and weakly bonded old snow require caution.

Weak layers in the old snowpack represent the main danger. Wind slabs require caution.
Weak layers in the old snowpack can still be released in some places by individual winter sport participants. The avalanche prone locations are to be found in particular on very steep shady slopes above approximately 2200 m. Such avalanche prone locations are barely recognisable, even to the trained eye. Avalanches can reach medium size.
Wind slabs can be released by a single winter sport participant in some cases on very steep shady slopes above approximately 2400 m, especially adjacent to ridgelines. The mostly small wind slabs are clearly recognisable to the trained eye.
As a consequence of warming during the day and the solar radiation, the likelihood of moist loose snow slides being released will increase a little on extremely steep south facing slopes.

Shady slopes: Avalanche prone weak layers exist in the centre of the snowpack in particular on little used shady slopes. As a consequence of a moderate wind, wind slabs formed adjacent to ridgelines. These are lying on soft layers at elevated altitudes.
Sunny slopes: The snowpack will be in most cases well bonded. The solar radiation will give rise as the day progresses to increasing softening of the snowpack on steep sunny slopes. Below the tree line only a little snow is now lying.
Tendency
Weak layers in the old snowpack represent the main danger. As a consequence of warming during the day and the solar radiation, the likelihood of wet snow slides being released will increase a little in particular on extremely steep sunny slopes.
Danger level
Wind slabs require caution.
Fresh wind slabs are in individual cases still prone to triggering. Caution is to be exercised in particular on very steep shady slopes adjacent to ridgelines and in gullies and bowls above approximately 2000 m. Mostly avalanches are small.

Snowpack
dp.6: cold, loose snow and wind
The mostly small wind slabs are lying on soft layers in particular on shady slopes at elevated altitudes.
The snowpack will be moist at low and intermediate altitudes. Only a small amount of snow is lying for the time of year.
Tendency
The weather conditions will facilitate a rapid stabilisation of the snowpack.
