Wind slabs and weakly bonded old snow represent the main danger.
Weak layers in the old snowpack can be released even by individual winter sport participants. This applies in particular on very steep shady slopes above approximately 2000 m, as well as on very steep east and west facing slopes above approximately 2400 m. Caution is to be exercised at transitions from a shallow to a deep snowpack. As the day progresses the likelihood of avalanches being released will increase a little. Fresh wind slabs can be released by a single winter sport participant in some cases. Such avalanche prone locations are to be found in particular on steep northwest, north and east facing slopes above approximately 2400 m, especially adjacent to ridgelines. As a consequence of warming during the day and solar radiation small to medium-sized loose snow avalanches are to be expected. On steep grassy slopes more frequent small gliding avalanches are to be expected.
Snowpack
dp.1: deep persistent weak layer dp.6: cold, loose snow and wind
Faceted weak layers exist in the old snowpack, especially on shady slopes above approximately 2000 m, as well as on west and east facing slopes above approximately 2400 m. Over a wide area 25 to 40 cm of snow has fallen since Tuesday above approximately 1800 m. As a consequence of new snow and a sometimes strong wind, extensive wind slabs formed. These are lying on soft layers on steep shady slopes at high altitudes and in high Alpine regions. The solar radiation will give rise to increasing moistening of the snowpack especially at low and intermediate altitudes. The meteorological conditions will bring about a slight weakening of the snowpack as the day progresses.
Tendency
Thursday: Gradual increase in avalanche danger as a consequence of warming.

Fresh and older wind slabs represent the main danger.
The new snow and wind slabs can be released easily, even by a single winter sport participant,. The avalanche prone locations are to be found in particular on northwest to north to east facing aspects above approximately 2200 m. Caution is to be exercised adjacent to ridgelines and in pass areas, as well as in gullies and bowls. The avalanche prone locations are sometimes covered with new snow and are difficult to recognise. At elevated altitudes the avalanche prone locations are more prevalent. Backcountry touring calls for experience in the assessment of avalanche danger.

Over a wide area 10 to 20 cm of snow, and even more in some localities, fell on Tuesday. As a consequence of new snow and a strong wind, sometimes avalanche prone wind slabs formed. In some cases the various wind slabs have bonded still only poorly with each other and the old snowpack. As a consequence of the strong wind the wind slabs will increase in size additionally on Wednesday.
Tendency
The weather conditions will prevent a rapid stabilisation of the snowpack.

Over a wide area 20 to 30 cm of snow, and even more in some localities, has fallen since Tuesday, in particular in the eastern part of the main Alpine ridge and in the Ortler Range. As a consequence of new snow and a strong wind, sometimes avalanche prone wind slabs formed. The new snow and wind slabs are lying on the unfavourable surface of an old snowpack in particular on shady slopes at high altitudes and in high Alpine regions. In some cases the various wind slabs have bonded still only poorly with each other and the old snowpack. As a consequence of the strong wind the wind slabs will increase in size additionally on Wednesday. Faceted weak layers exist in the old snowpack, especially on shady slopes above approximately 2200 m, as well as on east and west facing slopes above approximately 2400 m. The solar radiation will give rise as the day progresses to slight moistening of the snowpack in particular on sunny slopes.
Tendency
The weather conditions facilitated a gradual stabilisation of the snow drift accumulations. As a consequence of warming during the day and solar radiation wet snow slides and avalanches are to be expected.
