Even single freeriders can release avalanches easily.
For those venturing off piste a dangerous avalanche situation will persist.
Large quantities of fresh snow and the wind-drifted snow of the last few days are lying on top of a weakly bonded old snowpack. Areas close to the tree line as well as above the tree line: Winter sport participants can release avalanches easily. Avalanches can in some cases penetrate deep layers and reach large size, in particular on west, north and east facing slopes. The avalanche prone locations are numerous. Individual avalanche prone locations are to be found also on southeast, south and southwest facing slopes above approximately 2600 m. Caution is to be exercised in particular in little used terrain, as well as at transitions from a shallow to a deep snowpack, when entering gullies and bowls for example. Remotely triggered avalanches are possible.
As a consequence of the rain, the likelihood of wet slab avalanches being released will increase in all aspects below approximately 2000 m. In particular on very steep west, north and east facing slopes the wet avalanches can penetrate even deep layers and reach large size in isolated cases.
In addition gliding avalanches are possible. This applies especially on cut and grassy slopes below approximately 2000 m.
Snowpack
dp.7: snow-poor zones in snow-rich surrounding dp.3: rain
Tuesday: Up to 15 cm of snow, and even more in some localities, will fall above approximately 2000 m. Up to intermediate altitudes rain will fall. The wind will be strong to storm force in some cases.
The snowpack will be prone to triggering. Large quantities of fresh snow and the wind-drifted snow of the last few days are bonding only slowly with the old snowpack. The various wind slabs have bonded insufficiently with each other and the old snowpack. Avalanche prone weak layers exist in the bottom section of the snowpack on west, north and east facing slopes.
The rain gave rise to softening of the snowpack at low and intermediate altitudes.
Tendency
Hardly any decrease in danger of dry avalanches. Gradual increase in danger of wet avalanches as a consequence of warming.

Wind slabs remain prone to triggering. Caution is to be exercised in particular on west, north and east facing slopes in areas close to the tree line, as well as above the tree line. Individual avalanche prone locations are to be found also on southeast, south and southwest facing slopes above approximately 2400 m. Avalanches can be released in near-surface layers of the snowpack. Additionally avalanches can also be released in deep layers and reach large size on west, north and east facing slopes. 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.
As a consequence of warming during the day and solar radiation wet loose snow avalanches are possible. This applies especially on very steep sunny slopes below approximately 2200 m.
Snowpack
dp.1: deep persistent weak layer
5 to 10 cm of snow, and even more in some localities, will fall. The sometimes storm force wind will transport the snow. Further wind slabs will form.
The snowpack will be prone to triggering over a wide area. The new snow and wind slabs are lying on the unfavourable surface of an old snowpack. Distinct weak layers exist in the bottom section of the old snowpack. This applies in particular on west, north and east facing slopes in areas close to the tree line, and above the tree line.
The weather conditions as the day progresses will give rise to thorough wetting of the snowpack. This applies especially on very steep sunny slopes below approximately 2200 m.

Gradual decrease in danger of dry avalanches. Increase in danger of wet avalanches as a consequence of warming.

In little used terrain a dangerous avalanche situation will prevail.
As a consequence of new snow and a strong to storm force northwesterly wind, further wind slabs will form in gullies and bowls and behind abrupt changes in the terrain. The new snow and wind slabs of the last few days are lying on top of a weakly bonded old snowpack. This applies on west, north and east facing slopes. The avalanche prone locations are numerous, especially in areas close to the tree line, as well as above the tree line. Winter sport participants can release avalanches easily, including large ones. Natural avalanches are still even now possible.
In addition wet and gliding avalanches are possible. This applies especially on cut and grassy slopes below approximately 1800 m. In places where a lot of rain falls the avalanche danger is greater. This applies in particular in the Kitzbühel Alps.

The snowpack will be prone to triggering over a wide area. The new snow and wind slabs are lying on top of a weakly bonded old snowpack. Distinct weak layers exist in the bottom section of the old snowpack. This applies in particular on west, north and east facing slopes in areas close to the tree line, and above the tree line.
The rain will give rise as the day progresses to gradual and thorough wetting of the snowpack at low altitude.

The wind will transport the snow. Further wind slabs will form.
The snowpack will be prone to triggering over a wide area. 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.

Shady slopes: Weakly bonded old snow requires caution. Very steep sunny slopes: Increase in danger of wet avalanches as a consequence of warming.
Avalanches can be released in the old snowpack and reach large size in isolated cases on west, north and east facing slopes. This applies in case of a single winter sport participant. The avalanche prone locations are to be found in particular above the tree line. In their paths avalanches can entrain the wet snow. This extends the avalanche runout distances.
As a consequence of warming during the day and solar radiation small and medium-sized wet avalanches are possible. This applies in particular on very steep sunny slopes below approximately 2200 m. The runout zones are to be treated with caution.

Distinct weak layers exist in the old snowpack in particular on west, north and east facing slopes.
Outgoing longwave radiation during the night will be reduced at times. The weather conditions as the day progresses will give rise to thorough wetting of the snowpack. This applies on very steep sunny slopes below approximately 2200 m.

Outside marked and open pistes a precarious avalanche situation will prevail. Weakly bonded old snow requires caution. In addition the danger of wet avalanches will increase.
Wind slabs are very prone to triggering in all aspects above approximately 2000 m. 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 large size on west, north and east facing slopes. As a consequence of the strong northwesterly wind individual natural avalanches are possible. The runout zones are to be avoided. Remotely triggered avalanches are possible.
In the regions neighbouring those that are subject to danger level 4 (high) the avalanche prone locations are larger.
As the penetration by moisture increases small and medium-sized wet avalanches are possible. In the event of rain this applies especially below approximately 2200 m. In addition a latent danger of gliding avalanches exists. This applies in particular on cut and grassy slopes.
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, will fall. As a consequence of new snow and strong wind the wind slabs will increase in size additionally. Somewhat older wind slabs are lying on surface hoar in some places. Distinct weak layers exist in the old snowpack in particular on west, north and east facing slopes. Avalanches triggered by explosives and natural avalanches have confirmed the existence of a weak snowack.
Outgoing longwave radiation during the night will be reduced. The weather conditions as the day progresses will give rise to gradual and thorough wetting of the snowpack. In the event of rain this applies especially below approximately 2200 m.
Tendency
The snowpack remains prone to triggering. The activity of wet avalanches will gradually increase.
