Weakly bonded old snow and wet snow require caution.
Weakly bonded old snow requires caution. Avalanches can be released in the old snowpack, even by a single winter sport participant. They can in isolated cases release deeper layers of the snowpack and reach quite a large size. Avalanche prone locations are to be found especially above approximately 2000 m. These avalanche prone locations are to be found in particular in northwest to north to northeast facing aspects. Caution is to be exercised in particular on steep shady slopes, as well as at transitions from a shallow to a deep snowpack, when entering gullies and bowls for example.
Outgoing longwave radiation during the night was reduced. In the late morning the likelihood of slab avalanches being released will increase in particular on steep south and southwest facing slopes below the tree line.
As a consequence of warming during the day individual mostly small wet loose snow avalanches are possible.
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 northwest, north and northeast facing slopes. This applies especially above approximately 2000 m.
Outgoing longwave radiation during the night was reduced. The surface of the snowpack is frozen, but not to a significant depth and will soften during the day. This applies in particular below approximately 2400 m.
The snowpack remains subject to considerable local variations over a wide area.
Tendency
Outgoing longwave radiation during the night was quite good over a wide area. The danger of moist and wet avalanches will increase during the day.

Weakly bonded old snow requires caution.
Winter sport participants can release avalanches in isolated cases. These can reach large size in isolated cases. The avalanche prone locations are to be found in particular on very steep west, north and east facing slopes 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.

dp.7: snow-poor zones in snow-rich surrounding
Some snow will fall especially in the Allgäu Alps and in the Western Lechtal Alps.
Above approximately 2000 m: Avalanche prone weak layers exist in the bottom section of the snowpack on west, north and east facing slopes. Towards its surface, the snowpack consists of faceted crystals, especially on shady slopes. In steep terrain there is a danger of falling on the hard snow surface.
Below approximately 2000 m: The snowpack will be moist.
Tendency
Weakly bonded old snow requires caution. Slight increase in danger of moist 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 isolated cases be released in the old snowpack and reach medium size in isolated cases on northwest, north and northeast facing slopes. They can be released, even by a single winter sport participant. Outgoing longwave radiation during the night was reduced. In the late morning the likelihood of slab avalanches being released will increase in particular on steep southeast and southwest facing slopes below approximately 2400 m. As a consequence of warming during the day individual mostly small wet loose snow avalanches are possible.

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.

Little snow will fall.
Above approximately 2000 m: Avalanche prone weak layers exist in the bottom section of the snowpack on northwest, north and northeast facing slopes. In steep terrain there is a danger of falling on the hard snow surface.
Below approximately 2000 m: The snowpack will be moist. The weather conditions as the day progresses will give rise to slight softening of the snowpack.
Tendency
Slight increase in danger of moist avalanches as a consequence of warming during the day and solar radiation.
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.
Snowpack
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.
