Danger level
Danger Level 4 - High
Avalanche Problem
Gliding snow above 2500m, N-NE-E-SE-S-SW-W-NW
Wind-drifted snow above 2000m, N-NE-E-SE-S-SW-W-NW


Numerous large and, in many cases, very large natural avalanches are to be expected as the precipitation becomes more intense. A critical avalanche situation will prevail.

As the precipitation becomes more intense numerous natural avalanches are to be expected, even very large ones. Gliding avalanches and dry slab avalanches are the main danger. On steep grassy slopes numerous medium-sized and large gliding avalanches are to be expected below approximately 2500 m. In the regions where a lot of rain falls the danger will increase more quickly.
As a consequence of warming, the likelihood of dry slab avalanches being released will increase appreciably. Numerous large and, in many cases, very large avalanches are to be expected, this applies in particular from early morning. The prevalence of avalanche prone locations and likelihood of triggering will increase with altitude.
Additionally in some places dry avalanches can also be released in near-ground layers and reach very large size as the day progresses. This applies in all aspects in high Alpine regions.
Outside marked and open pistes a critical avalanche situation will prevail.

Snowpack

dp 2: gliding snow
dp 6: cold, loose snow and wind

Over a wide area 50 to 80 cm of snow, and up to 120 cm in some localities, fell. Over a wide area 50 to 80 cm of snow, and even more in some localities, will fall above approximately 1500 m, especially in the east. The wind will be strong to storm force. As a consequence of fresh snow and a storm force southerly wind, extensive wind slabs will form in all aspects.
The snowpack will be generally prone to triggering. Over a wide area fresh snow and wind slabs are lying on soft layers, especially above approximately 2000 m. The old snowpack will be unstable in high Alpine regions. Dry avalanches can be released in near-ground layers.
The snowpack will become wet all the way through at low and intermediate altitudes.

Tendency

Gradual decrease in avalanche danger.

Danger level
Danger Level 3 - Considerable above 2000m
Danger Level 2 - Moderate above 2000m
Avalanche Problem
Wind-drifted snow above 2000m, N-NE-E-SE-S-SW-W-NW
Gliding snow above 2500m, N-NE-E-SE-S-SW-W-NW


Fresh wind slabs above approximately 2000 m. Gliding avalanches and snow slides below approximately 2500 m.

The fresh wind slabs represent the main danger. These are to be evaluated with care and prudence in all aspects above approximately 2000 m. At elevated altitudes the prevalence and size of the avalanche prone locations will increase on Sunday. As a consequence of warming, the likelihood of slab avalanches being released will increase.
In addition a certain danger of gliding avalanches and snow slides exists, in the regions exposed to a lot of fresh snow especially, in the regions exposed to rain this also applies.

Snowpack

dp 6: cold, loose snow and wind
dp 2: gliding snow

As a consequence of a strong to storm force southerly wind, wind slabs formed since Thursday at elevated altitudes. From the second half of the night the previously small wind slabs will increase in size additionally. In some places wind slabs are lying on soft layers, especially above approximately 2000 m. The snowpack will become wet all the way through at low and intermediate altitudes.

Tendency

Gradual decrease in avalanche danger.
