Increase in avalanche danger as a consequence of new snow and strong wind. Natural avalanches are to be expected.
Outside marked and open pistes a very dangerous avalanche situation will prevail. The danger exists in particular in alpine snow sports terrain.
The fresh snow and the sometimes large wind slabs that are forming in all aspects can be released very easily above the tree line. Such avalanche prone locations are to be found also in areas close to the tree line. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack and fresh avalanches serve as an alarm indicating the danger. Remotely triggered avalanches are possible.
The number and size of avalanche prone locations will increase from midday. As a consequence of new snow and strong wind more frequent natural avalanches are to be expected. Avalanches can in some cases penetrate deep layers and reach large size, especially on steep west, north and east facing slopes.
On very steep slopes small and, in isolated cases, medium-sized loose snow avalanches are possible, in the event of rain this also applies at low and intermediate altitudes.
Snowpack
dp.1: deep persistent weak layer dp.6: cold, loose snow and wind
15 to 30 cm of snow, and even more in some localities, will fall on Thursday. The wind will be strong in some cases. The wind will transport the new snow. Further wind slabs will form.
The snowpack will be prone to triggering over a wide area. The meteorological conditions will bring about a substantial weakening of the snowpack in the afternoon. The new snow and wind slabs are lying on top of a weakly bonded old snowpack. Somewhat older wind slabs are lying on surface hoar. Distinct weak layers exist in the bottom section of the old snowpack. This applies in particular on west, north and east facing slopes above the tree line.
Tendency
The off-piste conditions are very dangerous. Weak layers in the old snowpack represent the main danger.
10 to 20 cm of snow will fall during the night. This applies in particular in the north, in the Tuxer Alps, in the Zillertal Alps and in the High Tauern.

Remotely triggered and natural avalanches are to be expected.
From the middle of the day a precarious avalanche situation will prevail. The avalanche danger in the regions exposed to heavier precipitation is within the upper range of danger level 3 (considerable).
Late morning: In particular on wind-loaded slopes avalanches can be triggered in the faceted old snow and reach medium size. This applies even in case of a single winter sport participant in some cases. Caution is to be exercised in particular on west, north and east facing slopes above approximately 1800 m.
Increase in avalanche danger from the middle of the day. As a consequence of new snow and a moderate to strong wind from variable directions, precarious wind slabs will form from the middle of the day. These can be released in near-surface layers of the snowpack. Avalanches can also penetrate near-ground layers of the snowpack and reach quite a large size on west, north and east facing slopes. Natural avalanches are to be expected. The runout zones are to be avoided. The emptied starting zones will be replenished as a consequence of snowfall and wind. In addition an appreciable danger of loose snow avalanches exists.
Snowpack
dp.1: deep persistent weak layer dp.8: surface hoar blanketed with snow
20 to 40 cm of snow, and even more in some localities, will fall from midday. The sometimes strong wind will transport the new snow. The snowpack will become increasingly prone to triggering. Somewhat older wind slabs are lying on surface hoar in some places. Over a wide area further wind slabs will form. Distinct weak layers exist in the old snowpack in particular on west, north and east facing slopes.
Tendency
During the course of the night as a consequence of new snow and wind there will be an additional increase in the avalanche danger. The snowpack will be prone to triggering over a wide area.

In the afternoon a precarious avalanche situation will prevail. The avalanche danger in the regions exposed to heavier precipitation is within the upper range of danger level 3 (considerable).
Wind slabs are very prone to triggering in all aspects. These can in many cases be released in near-surface layers of the snowpack. Avalanches can also penetrate near-ground layers of the snowpack and reach quite a large size on west, north and east facing slopes. Midday and afternoon: As a consequence of new snow and a moderate to strong wind from variable directions, further wind slabs will form in the course of the day. As the snowfall becomes heavier, the likelihood of avalanches being released will increase significantly. Natural avalanches are possible. The runout zones are to be avoided. The emptied starting zones will be replenished as a consequence of snowfall and wind.
