A treacherous avalanche situation will prevail. Weakly bonded old snow requires caution. Wind slabs are to be avoided.
Avalanches can be released in the weakly bonded old snow, even by a single winter sport participant. This applies in particular on west, north and east facing slopes above approximately 1800 m, in isolated cases also on south facing slopes above approximately 2400 m. Mostly avalanches are medium-sized. Remotely triggered avalanches are possible. In addition the fresh wind slabs in particular above the tree line are prone to triggering. Wind slabs will be covered with new snow in some cases and therefore difficult to recognise.
The number and size of avalanche prone locations will increase with altitude. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack serve as an alarm indicating the danger.
Snowpack
dp.1: deep persistent weak layer dp.8: surface hoar blanketed with snow
5 to 10 cm of snow has fallen since Tuesday. Up to 10 cm of snow will fall. As a consequence of the sometimes strong wind the wind slabs will increase in size additionally. These are lying on surface hoar in particular on wind-protected shady slopes. The snowpack is unfavourably layered. Distinct weak layers exist in the old snowpack. This applies in particular on west, north and east facing slopes above approximately 1800 m.
Tendency
The avalanche conditions remain precarious. In some regions up to 30 cm of snow will fall. As a consequence of new snow and wind the wind slabs will increase in size. Wind slabs will be covered with new snow in some cases and therefore difficult to recognise.

As a consequence of new snow and wind an unfavourable avalanche situation will prevail.
Weak layers in the upper part of the snowpack can be released easily by individual winter sport participants in gullies and bowls and behind abrupt changes in the terrain. This applies in particular on west, north and east facing slopes above approximately 1600 m. Avalanches can release deeper layers of the snowpack and reach medium size in particular along the border with Friuli. Individual natural avalanches are possible.
The number and size of avalanche prone locations will increase with altitude. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack indicate the danger. Remotely triggered avalanches are possible in isolated cases.
Snowpack
dp.1: deep persistent weak layer dp.6: cold, loose snow and wind
10 to 20 cm of snow, and even more in some localities, has fallen since Tuesday. Up to 15 cm of snow will fall. The snowpack is unfavourably layered. As a consequence of a gusty southerly wind, soft wind slabs formed. These are lying on surface hoar in particular on wind-protected shady slopes. In the course of the day the wind slabs will increase in size once again. The snowpack will become increasingly prone to triggering. Distinct weak layers exist in the old snowpack. This applies in particular on west, north and east facing slopes above approximately 1800 m.
Tendency
The avalanche conditions remain unfavourable. The new snow of Thursday will be deposited on a weakly bonded old snowpack. The snowpack will become increasingly prone to triggering.

The conditions are unfavourable.
Weak layers in the upper part of the snowpack can be released easily by individual winter sport participants in gullies and bowls and behind abrupt changes in the terrain. This applies especially on west, north and east facing slopes above approximately 1800 m. Avalanches can release deeper layers of the snowpack and reach medium size in particular along the border with Slovenia.
The number and size of avalanche prone locations will increase with altitude. They are barely recognisable. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack indicate the danger.
As a consequence of the rain individual small wet loose snow avalanches are possible.

In particular along the border with Slovenia 5 to 15 cm of snow has fallen since Tuesday above approximately 1200 m. 10 to 15 cm of snow, and even more in some localities, will fall above approximately 1500 m. The new snow and wind slabs are lying on surface hoar on wind-protected shady slopes. The old snowpack is faceted and weak. The rain will give rise as the day progresses to thorough wetting of the snowpack below approximately 1500 m.
Tendency
The avalanche conditions remain unfavourable. The new snow of Thursday will be deposited on a weakly bonded old snowpack. The snowpack will become increasingly prone to triggering.

The fresh wind slabs will be deposited on surface hoar. Weak layers in the old snowpack necessitate caution.
The fresh wind slabs will be deposited on the unfavourable surface of an old snowpack on west to north to east facing aspects. These can be released easily. or in isolated cases naturally,. Avalanches can release the weakly bonded old snow as well and reach medium size. Caution is to be exercised in particular on wind-loaded slopes, as well as in gullies and bowls, and behind abrupt changes in the terrain above the tree line.
The number and size of avalanche prone locations will increase with altitude. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack serve as an alarm indicating the danger.

Tendency
The avalanche conditions remain unfavourable. As a consequence of new snow and wind the wind slabs will increase in size. Weak layers in the old snowpack can still be released by individual winter sport participants.

Weakly bonded old snow represents the main danger.
Avalanches can be released in the weakly bonded old snow by a single winter sport participant. This applies in particular on west, north and east facing slopes above approximately 1800 m. In very isolated cases avalanches are medium-sized.
Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack can indicate the danger.
