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


As a consequence of fresh snow and stormy weather a critical avalanche situation will be encountered in some regions. Gliding avalanches and dry slab avalanches are the main danger.

Natural avalanches must be expected.
On steep grassy slopes numerous medium-sized and, in many cases, large gliding avalanches are to be expected below approximately 2500 m.
In addition a substantial danger of dry slab avalanches exists, in particular above the tree line. Numerous medium-sized to large avalanches are to be expected. These can be released easily. The prevalence of avalanche prone locations and likelihood of triggering will increase with altitude. As the snowfall becomes more intense the prevalence and size of the avalanche prone locations will increase during the course of the night, in particular in the northeast.
Additionally in some places dry avalanches can also be released in near-ground layers and reach very large size in isolated cases during the course of the night. This applies in all aspects in high Alpine regions.
Outside marked and open pistes a critical avalanche situation will prevail.

Snowpack

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

Over a wide area 40 to 80 cm of snow, and even more in some localities, has fallen thus far. Over a wide area 30 to 50 cm of snow. will fall until the early morning, especially in the northeast. 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 the tree line. The old snowpack will be unstable in high Alpine regions. Dry avalanches can be released in near-ground layers.
The snowpack will be moist at low and intermediate altitudes.

Tendency

A critical avalanche situation will persist. High, level 4.
