Weakly bonded old snow represents the main danger.
Weakly bonded old snow requires caution. Avalanches can in some cases be released in the old snowpack and reach quite a large size on west, north and east facing slopes. This applies even in case of a single winter sport participant in some cases. The avalanche prone locations are to be found in particular above approximately 2000 m. Caution is to be exercised in particular at transitions from a shallow to a deep snowpack, when entering gullies and bowls for example.
In the late morning the likelihood of slab avalanches being released will increase a little in particular on steep sunny slopes at elevated altitudes. As a consequence of warming during the day individual mostly small wet loose snow avalanches are possible. Backcountry tours and off-piste skiing should be concluded timely.
Snowpack
dp.1: deep persistent weak layer dp.10: springtime scenario
Shady slopes: Distinct weak layers exist in the bottom section of the snowpack in particular on west, north and east facing slopes. This applies especially above approximately 2000 m.
Outgoing longwave radiation during the night will be reduced in some case. The surface of the snowpack will freeze to form a strong crust only at high altitudes. The weather conditions as the day progresses will give rise to softening of the snowpack in particular on sunny slopes.
Towards its surface, the snowpack consists of faceted crystals, especially on shady slopes at elevated altitudes.
In steep terrain there is a danger of falling on the hard snow surface.
Tendency
The weather will be mild. The danger of moist and wet avalanches will increase a little during the day.

Weakly bonded old snow requires caution.
Winter sport participants can release avalanches in isolated cases. These can reach large size. The avalanche prone locations are to be found in particular on very steep northwest, north and northeast facing slopes above approximately 2000 m and on very steep west and east facing slopes above approximately 2200 m. Caution is to be exercised in particular at transitions from a shallow to a deep snowpack, when entering gullies and bowls for example.
As a consequence of warming during the day and the solar radiation, the likelihood of slab avalanches being released will increase a little on steep sunny slopes.

dp.7: snow-poor zones in snow-rich surrounding dp.10: springtime scenario
Distinct weak layers exist in the bottom section of the snowpack on west, north and east facing slopes, in particular above approximately 2000 m.
Towards its surface, the snowpack consists of faceted crystals, especially on shady slopes at elevated altitudes.
Outgoing longwave radiation during the night will be reduced in some case.
In steep terrain there is a danger of falling on the hard snow surface. The weather conditions as the day progresses will give rise to slight softening of the snowpack on very steep sunny slopes.
Tendency
Weakly bonded old snow requires caution. Slight increase in danger of wet avalanches as a consequence of warming during the day and solar radiation.

Weak layers in the old snowpack can still be released in isolated cases.
Avalanches can in very isolated cases be released in the old snowpack and reach medium size in isolated cases on northwest, north and northeast facing slopes. This applies in case of a single winter sport participant.
As a consequence of warming during the day individual wet avalanches are possible.
Snowpack
dp.1: deep persistent weak layer dp.10: springtime scenario
Shady slopes: Avalanche prone weak layers exist in the old snowpack in particular on northwest, north and northeast facing slopes.
Sunny slopes: The weather conditions gave rise to moistening of the snowpack below approximately 2500 m.
Tendency
The weather will be mild. The danger of moist and wet avalanches will increase a little during the day.
Danger level
Low avalanche danger will prevail.
Only isolated dry avalanches are possible. They can be released, in particular by large loads, but they will be small in most cases. Individual avalanche prone locations are to be found on steep shady slopes at high altitude.
As a consequence of warming during the day only isolated wet avalanches are possible.

Shady slopes: Avalanche prone weak layers exist in the old snowpack in particular on northwest, north and northeast facing slopes.
Sunny slopes: The weather conditions gave rise to moistening of the snowpack.
Tendency
Low avalanche danger will prevail.
Danger level
A generally favourable avalanche situation will prevail.
Individual avalanche prone locations for dry avalanches are to be found in particular on very steep shady slopes above approximately 2000 m. Mostly avalanches are medium-sized. Apart from the danger of being buried, restraint should be exercised in particular in view of the danger of avalanches sweeping people along and giving rise to falls. As a consequence of warming during the day and the solar radiation, the likelihood of slab avalanches being released will increase a little.
