Danger level
Danger Level 3 - Considerable above 2000m
No Rating above 2000m

Wind-drifted snow above 2000m, N-NE-E-SE-S-SW-W-NW

Considerable, level 3. Fresh wind slabs represent the main danger.

The Avalanche Warning Service currently has only a small amount of information that has been collected in the field.
Down to 1800 m snow has fallen over a wide area. As a consequence of the sometimes strong wind the previously small wind slabs have increased in size additionally. The avalanche prone locations are to be found in particular adjacent to ridgelines and in gullies and bowls in all aspects. Mostly avalanches are medium-sized but can be released in many cases even by a single winter sport participant. The number and size of avalanche prone locations will increase with altitude.
In the regions exposed to heavier precipitation and on steep sunny slopes small to medium-sized wet snow slides and avalanches are to be expected.

Snowpack

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

Over a wide area 10 to 40 cm of snow, and even more in some localities, fell above approximately 2000 m. Individual weak layers exist in the old snowpack on steep shady slopes, especially above approximately 2800 m. At low altitude no snow is lying.

Tendency

Increase in danger of moist and wet avalanches as a consequence of warming during the day and solar radiation. High altitudes and the high Alpine regions: Wind slabs require caution.

Danger level
Danger Level 2 - Moderate above 2000m

Avalanche Problem
Wet snow above 2000m, N-NE-E-SE-S-SW-W-NW
Wind-drifted snow above 2800m, N-NE-NW


Already in the late morning numerous mostly small moist loose snow avalanches are to be expected. High Alpine regions: Fresh wind slabs require caution.

The Avalanche Warning Service currently has only a small amount of information that has been collected in the field. In the regions exposed to heavier precipitation small and, in isolated cases, medium-sized moist loose snow avalanches are to be expected. This applies above approximately 2000 m on extremely steep slopes. The prevalence of avalanche prone locations will increase with altitude.
High Alpine regions: In addition the rather small wind slabs of yesterday adjacent to ridgelines are prone to triggering in isolated cases.

Snowpack

dp 10: springtime scenario
dp 6: cold, loose snow and wind

In some regions over a wide area 5 to 10 cm of snow. fell above approximately 2000 m. The wind was moderate. In very isolated cases wind slabs are lying on soft layers. This applies in particular on shady slopes above approximately 3000 m. The snowpack will become increasingly moist. Outgoing longwave radiation during the night will be reduced in some places. At low altitude no snow is lying.

Tendency

The danger of moist loose snow avalanches will persist.

As a consequence of the ceasing of precipitation numerous mostly small moist loose snow avalanches are to be expected. High Alpine regions: Fresh wind slabs require caution.

The Avalanche Warning Service currently has only a small amount of information that has been collected in the field. In the regions exposed to heavier precipitation small and, in isolated cases, medium-sized moist loose snow avalanches are to be expected. This applies above approximately 2000 m on extremely steep slopes. The prevalence of avalanche prone locations will increase with altitude.
High Alpine regions: In addition the rather small wind slabs of yesterday adjacent to ridgelines are prone to triggering in isolated cases. This applies in particular above approximately 3000 m on very steep shady slopes,, also on very steep sunny slopes, in particular in the regions of the south that are exposed to the foehn wind. Such avalanche prone locations are rare. In regions exposed to the foehn wind avalanche prone locations are more widespread.

Snowpack

dp 10: springtime scenario
dp 6: cold, loose snow and wind

In some regions 5 to 10 cm of snow, and even more in some localities, will fall above approximately 2000 m. The wind will be moderate to strong adjacent to ridgelines in particular in the regions exposed to the foehn wind. In very isolated cases wind slabs are lying on soft layers, especially above approximately 3000 m. The snowpack will become increasingly moist. Outgoing longwave radiation during the night will be barely evident. At low altitude no snow is lying.

Tendency

The danger of moist loose snow avalanches will persist.

Low, level 1.

The Avalanche Warning Service currently has only a small amount of information that has been collected in the field.
Over a wide area wind and fresh snow above approximately 2000 m. The snowpack remains in most cases moist. Moist and wet avalanches are possible even now.

Snowpack

dp 3: rain

In some regions 2 to 10 cm of snow. fell above approximately 2000 m. The fresh snow is bonding quite well with the old snowpack. Outgoing longwave radiation during the night will be reduced. At low altitude no snow is lying.

Tendency

Slight increase in danger of moist and wet avalanches as a consequence of warming during the day and solar radiation. The fresh snow must be evaluated with care and prudence above approximately 2000 m.
