Increase in danger of wet avalanches as a consequence of warming during the day and solar radiation. Weakly bonded old snow requires caution.
As a consequence of warming during the day and solar radiation more frequent wet avalanches are possible. They can in some cases release the saturated snowpack and reach large size in isolated cases. This applies in particular on very steep sunny slopes below approximately 2800 m.
Late morning: Weak layers in the old snowpack can be released in isolated cases by individual winter sport participants. These avalanche prone locations are to be found in particular on very steep shady slopes above approximately 2400 m and on very steep west and east facing slopes above approximately 2600 m. Afternoon: As a consequence of warming during the day and the solar radiation, the likelihood of slab avalanches being released will increase a little. Mostly the avalanches are medium-sized.
Gliding avalanches can also occur. Caution is to be exercised on grassy slopes below approximately 2600 m.
Snowpack
dp.10: springtime scenario dp.1: deep persistent weak layer
Outgoing longwave radiation during the night was good. The surface of the snowpack will freeze to form a strong crust. In steep terrain there is a danger of falling on the hard snow surface. The surface of the snowpack will soften during the day. Sunshine and high temperatures will give rise to increasing and thorough wetting of the snowpack in particular on sunny slopes below approximately 2800 m.
Avalanche prone weak layers exist in the old snowpack especially on little used west, north and east facing slopes. This applies on shady slopes above approximately 2400 m, as well as on west and east facing slopes above approximately 2600 m.
Tendency
Decrease in danger of wet avalanches as the temperature drops.

Increase in danger of wet avalanches as a consequence of warming during the day and solar radiation. Weakly bonded old snow requires caution.
During the day: As a consequence of warming during the day and the solar radiation, the likelihood of moist slab avalanches being released will increase significantly. Caution is to be exercised in particular on very steep sunny slopes below approximately 2800 m, as well as on very steep west facing slopes below approximately 2600 m. Avalanches can in some cases release the wet snowpack. Mostly the avalanches are medium-sized. Gliding avalanches can also occur, in particular on grassy slopes below approximately 2400 m. Early morning: Weak layers in the old snowpack can be released in isolated cases by individual winter sport participants. These avalanche prone locations are to be found in particular on very steep shady slopes above approximately 2400 m and on very steep west and east facing slopes above approximately 2600 m. As a consequence of warming during the day and the solar radiation, the likelihood of slab avalanches being released will increase appreciably.

The surface of the snowpack has frozen to form a strong crust and will soften earlier than the day before. Sunshine and high temperatures will give rise to increasing and thorough wetting of the snowpack over a wide area in all aspects below approximately 2800 m.
Avalanche prone weak layers exist in the old snowpack especially on little used west, north and east facing slopes. This applies on shady slopes above approximately 2400 m.
The snowpack will be subject to considerable local variations at intermediate altitudes. Below the tree line a little snow is lying.

The backcountry touring conditions in the morning, after a clear night, are favourable. As a consequence of warming during the day and the solar radiation, the likelihood of wet avalanches being released will increase. Caution is to be exercised in particular on very steep sunny slopes. Avalanches can in some cases release the saturated snowpack.
Gliding avalanches can also occur. This applies on grassy slopes below approximately 2600 m.

Small and medium-sized wet and gliding avalanches are possible as a consequence of warming during the day and solar radiation. As a consequence of warming during the day and the solar radiation, the likelihood of wet slab avalanches being released will increase in particular on grassy slopes at low and intermediate altitudes. Restraint should be exercised because avalanches can sweep people along and give rise to falls. Weak layers in the old snowpack can be released in some places in particular on steep shady slopes. These avalanche prone locations are rather rare and are difficult to recognise. The avalanche prone locations are to be found in particular on steep, little used shady slopes above approximately 1900 m. In isolated cases avalanches can also release deeper layers of the snowpack and reach medium size. Outgoing longwave radiation during the night was good. The surface of the snowpack has frozen to form a strong crust will soften earlier than the day before.
Individual weak layers exist in the old snowpack especially on steep shady slopes. The snowpack will be generally subject to considerable local variations. Below the tree line a little snow is lying.

The danger of moist and wet avalanches will increase during the day.
Avalanches can in very isolated cases be released by a single winter sport participant. The avalanche prone locations are to be found in particular on very steep shady slopes at elevated altitudes. As a consequence of solar radiation individual wet avalanches are possible. This applies on steep sunny slopes, as well as on steep west facing slopes. In regions neighbouring those that are subject to danger level 3 (considerable) the avalanche prone locations are more prevalent and the danger is greater. Mostly avalanches are small.
Snowpack
The surface of the snowpack will only just freeze and will soften quickly. Isolated avalanche prone weak layers exist in the old snowpack especially on steep shady slopes.
The snowpack will be generally subject to considerable local variations. Only a little snow is now lying.
