Danger level
Danger Level 1 - Low above 2800m
Danger Level 2 - Moderate above 2800m
Avalanche Problem
Gliding snow above 2600m above 2000m, NE-E-SE-S-SW-W-NW
Wet snow above 2800m, NE-E-SE-S-SW-W-NW


The danger of gliding avalanches and moist snow slides will already exist in the early morning.

The Avalanche Warning Service currently has only a small amount of information that has been collected in the field.
The surface of the snowpack cooled hardly at all during the overcast night and will already be soft in the early morning. Wet and gliding avalanches are the main danger. The avalanche prone locations are to be found in particular on northeast, south and northwest facing slopes below approximately 2800 m and on very steep slopes below approximately 2200 m. The avalanches can release the wet old snow as well and reach large size in isolated cases.
In addition a low (level 1) danger of dry slab avalanches exists. This applies in particular on extremely steep shady slopes above approximately 2400 m. The avalanches are rather small and can only be released by large loads.

Snowpack

dp 2: gliding snow
dp 10: springtime scenario

Outgoing longwave radiation during the night was severely restricted over a wide area. The surface of the snowpack has frozen to form a strong crust only at high altitudes. The snowpack will be wet all the way through at intermediate altitudes. At low altitude no snow is lying.
Individual weak layers exist deep in the old snowpack on shady slopes, especially above approximately 2400 m in areas where the snow cover is rather shallow.

Tendency

Temporary decrease in danger of gliding avalanches and wet snow slides as the temperature drops. High Alpine regions: Slight increase in danger of dry avalanches as a consequence of the sometimes strong wind.

Danger level
Danger Level 2 - Moderate above 2000m
Danger Level 1 - Low above 2000m
Avalanche Problem
Wet snow above 2000m, N-NE-E-SE-S-SW-W-NW
Gliding snow above the treeline, N-NE-E-SE-NW


At low and intermediate altitudes hardly any snow is lying. The danger of gliding avalanches and moist snow slides will already exist in the early morning.

The Avalanche Warning Service currently has only a small amount of information that has been collected in the field.
The surface of the snowpack will cool hardly at all during the overcast night and will already soften in the late morning. Gradual increase in danger until the temperature drops. Gliding avalanches and wet snow slides are the main danger. The avalanche prone locations are to be found in particular on steep shady slopes above approximately 2000 m, and adjacent to ridgelines and in gullies and bowls.

Snowpack

dp 10: springtime scenario

Outgoing longwave radiation during the night will be severely restricted. The surface of the snowpack will only just freeze and will soften earlier than the day before. Isolated avalanche prone weak layers exist in the old snowpack especially on very steep shady slopes. Below approximately 1700 m hardly any snow is lying.

Tendency

Temporary decrease in danger of wet and gliding avalanches as the temperature drops.
