Fresh wind slabs represent the main danger. Gliding snow requires caution.
The new snow and wind slabs can be released easily, even by a single winter sport participant, above the tree line. Very isolated natural avalanches are possible, especially in the Ultental and in the Ortler Range. The number and size of avalanche prone locations will increase with altitude. Weak layers in the old snowpack can still be released in isolated cases by individual winter sport participants. The avalanche prone locations are to be found in particular on west, north and east facing slopes above approximately 2400 m. Avalanches can reach large size in isolated cases.
As a consequence of warming during the day and solar radiation small to medium-sized loose snow avalanches are to be expected. In particular in the regions with a lot of snow more frequent medium-sized gliding avalanches are possible, especially below approximately 2600 m.
Snowpack
dp.6: cold, loose snow and wind dp.2: gliding snow
Over a wide area 15 to 30 cm of snow, and even more in some localities, fell on Tuesday. As a consequence of new snow and wind the wind slabs have increased in size appreciably, in particular at high altitudes and in high Alpine regions. They are prone to triggering.
Isolated avalanche prone weak layers exist deeper in the snowpack in particular on steep east, north and west facing slopes.
Tendency
The conditions will facilitate a gradual stabilisation of the snow drift accumulations. The weather conditions will give rise to increasing moistening of the snowpack also at elevated altitudes. Gliding avalanches and moist snow slides are to be expected.

Fresh wind slabs require caution. Weakly bonded old snow is to be evaluated with care and prudence.
As a consequence of new snow and a sometimes strong southerly wind, sometimes avalanche prone wind slabs formed in particular adjacent to ridgelines. This applies especially on steep shady slopes above approximately 2200 m. Single winter sport participants can release avalanches, including medium-sized ones. The number and size of avalanche prone locations will increase with altitude.
Avalanches can in isolated cases be triggered in the old snowpack and reach large size in isolated cases in particular on very steep west, north and east facing slopes. Such avalanche prone locations are to be found above approximately 2400 m.
As a consequence of warming during the day individual loose snow slides are to be expected as the day progresses, but they will be mostly small. On steep grassy slopes medium-sized gliding avalanches are possible, especially on sunny slopes below approximately 2600 m.
Snowpack
dp.6: cold, loose snow and wind dp.4: cold following warm / warm following cold
In some regions 5 to 15 cm of snow fell on Tuesday. The southerly wind has transported the new snow. Fresh wind slabs are lying on soft layers especially on shady slopes.
In isolated cases new snow and wind slabs are lying on a weakly bonded old snowpack, in particular on steep west, north and east facing slopes above approximately 2400 m.
Tendency
The conditions will facilitate a gradual stabilisation of the snow drift accumulations. The weather conditions will give rise to increasing moistening of the snowpack also at elevated altitudes. Gliding avalanches and moist snow slides are to be expected.

Gliding snow requires caution. Fresh wind slabs are to be avoided.
On steep grassy slopes small and medium-sized gliding avalanches are to be expected, in particular below approximately 2600 m.
The fresh wind slabs are in individual cases still prone to triggering on very steep shady slopes above approximately 2200 m. Avalanches can in some cases be released by a single winter sport participant, but they will be small in most cases. The prevalence of avalanche prone locations and likelihood of triggering will increase with altitude.
Snowpack
dp.2: gliding snow dp.6: cold, loose snow and wind
The sometimes strong wind has transported the new snow. In some cases wind slabs are lying on soft layers, in particular on shady slopes above approximately 2200 m.
The snowpack is wet. This applies on sunny slopes and at intermediate altitudes.
Tendency
Small to medium-sized wet and gliding avalanches are possible as a consequence of warming. The wind slabs can only be released in isolated cases.
