In some localities increase in danger of moist and wet snow slides as a consequence of warming during the day. Weak layers in the old snowpack can be released in very isolated cases.
The backcountry touring conditions in the morning, after a clear night, are mostly favourable. Moist loose snow avalanches are possible as the day progresses, but they will be mostly small. Avalanche prone locations are to be found in particular on very steep sunny slopes at elevated altitudes, in isolated cases also adjacent to ridgelines, as well as at the base of rock walls and behind abrupt changes in the terrain. In isolated cases avalanches can be released in the old snowpack and reach medium size. Such avalanche prone locations are to be found on very steep west, north and east facing slopes above approximately 2200 m, especially at transitions from a shallow to a deep snowpack, when entering gullies and bowls for example.
Snowpack
dp.10: springtime scenario
As a consequence of mild temperatures and solar radiation the snowpack consolidated. Outgoing longwave radiation during the night will be good over a wide area. The surface of the snowpack will soften during the day, in particular on steep sunny slopes at intermediate and high altitudes, as well as in all aspects at low altitude. Faceted weak layers exist in the bottom section of the snowpack on west, north and east facing slopes.
Tendency
In some localities increase in danger of moist and wet avalanches as a consequence of warming during the day and solar radiation.
Danger level
A generally favourable avalanche situation will prevail.
The older wind slabs can be released by a single winter sport participant, but they will be small in most cases. This applies in particular in the east. The avalanche prone locations are rare but are easy to recognise. Such avalanche prone locations are to be found in particular on near-ridge shady slopes at elevated altitudes.
As a consequence of warming during the day and solar radiation more wet loose snow avalanches are possible, even medium-sized ones, in particular on very steep sunny slopes.
On steep grassy slopes small to medium-sized gliding avalanches are possible. This applies in particular in the west and below approximately 2400 m.
Snowpack
The old wind slabs are lying on soft layers in particular on steep shady slopes.
Since Sunday the weather has been mild. As a consequence of mild temperatures and solar radiation a crust formed on the surface at the weekend, especially on sunny slopes. Outgoing longwave radiation during the night will be good. Steep sunny slopes, high altitudes: The surface of the snowpack will soften during the day.
Only a small amount of snow is lying for the time of year.
Tendency
A generally favourable avalanche situation will prevail. Slight increase in danger of moist and wet avalanches as a consequence of warming.
Danger level
A mostly favourable avalanche situation will prevail. On very steep sunny slopes the danger of moist and wet avalanches will increase during the day.
In some localities increase in danger of moist and wet avalanches as a consequence of warming during the day. The avalanche prone locations are to be found in particular on very steep sunny slopes at elevated altitudes and adjacent to ridgelines and in gullies and bowls.
Snowpack
dp.10: springtime scenario
In all altitude zones less snow than usual is lying. As a consequence of highly fluctuating temperatures and solar radiation the snowpack consolidated. These weather conditions as the day progresses will give rise to increasing moistening of the snowpack in particular on steep sunny slopes.
Tendency
The avalanche danger will persist.

A clear night will be followed in the early morning by quite favourable conditions generally. Weak layers in the old snowpack can be released in very isolated cases.

Snowpack
dp.10: springtime scenario dp.1: deep persistent weak layer
Outgoing longwave radiation during the night will be good over a wide area. Especially on steep sunny slopes, a partially stable melt-freeze crust formed. Sunshine and high temperatures will give rise as the day progresses to a loss of strength within the snowpack in some cases on very steep sunny slopes.
Faceted weak layers exist in the bottom section of the snowpack on west, north and east facing slopes. The older wind slabs are lying on soft layers in particular on shady slopes.
Tendency
A clear night will be followed in the early morning by quite favourable conditions generally. Gradual increase in danger of moist and wet avalanches as a consequence of warming during the day and solar radiation.
