Danger level
Danger Level 2 - Moderate above 2000m
No Rating above 2000m
Avalanche Problem
Wet snow above 2000m, NE-E-SE-S-SW-W
Wind-drifted snow above 2800m, N-NE-E-SE-S-SW-W-NW


The danger of wet avalanches will already exist in the early morning. High Alpine regions: 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 and on steep sunny slopes small and, in isolated cases, medium-sized wet snow slides and avalanches are to be expected. As a consequence of warming during the day and the solar radiation, the likelihood of wet avalanches being released will increase above approximately 2000 m.
High Alpine regions: As a consequence of the moderate wind the previously small wind slabs will increase in size moderately. The avalanche prone locations are to be found in particular adjacent to ridgelines and in gullies and bowls in all aspects. The number and size of avalanche prone locations will increase with altitude.

Snowpack

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

Over a wide area 5 to 15 cm of snow, and even more in some localities, will fall. Outgoing longwave radiation during the night will be barely evident. The snowpack will be moist from early morning. In some cases the various wind slabs have bonded still only poorly together. At low altitude no snow is lying.

Tendency

Hardly any decrease in avalanche danger.

Danger level
Danger Level 2 - Moderate above 2000m
No Rating above 2000m
Avalanche Problem
Wind-drifted snow above 2400m, N-NE-E-SE-S-SW-W-NW
Wet snow above 2000m, NE-E-SE-S-SW


Wind slabs are to be evaluated with care and prudence. Wet avalanches as the day progresses.

The Avalanche Warning Service currently has only a small amount of information that has been collected in the field.
Down to 1800 m snow will fall over a wide area. As a consequence of the sometimes strong wind the previously small wind slabs will increase in size additionally. The avalanche prone locations are to be found in particular adjacent to ridgelines and in gullies and bowls in all aspects. In some cases 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. Danger level 2 (moderate) will be passed during the night above approximately 2400 m.
In the regions exposed to heavier precipitation and on steep sunny slopes small and, in isolated cases, 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 30 cm of snow, and even more in some localities, will fall 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 1 - Low above 1800m
No Rating above 1800m
Avalanche Problem
Wind-drifted snow above 2100m, N-NE-E-SE-S-SW-W-NW
Wet snow above 2400m above 1800m, N-NE-E-SE-S-SW-W-NW


As a consequence of fresh snow and wind individual slab avalanches are possible.

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 to above approximately 1800 m. As a consequence of fresh snow and wind individual slab avalanches are possible, but they will be mostly small. The snowpack remains in most cases moist. Moist and wet avalanches are possible even now.

Snowpack

dp 6: cold, loose snow and wind
dp 3: rain

In some regions 2 to 10 cm of snow, and even more in some localities, will fall above approximately 1800 m. The fresh snow is bonding quite well with the old snowpack below approximately 2100 m. Outgoing longwave radiation during the night will be severely restricted. 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.
