Natural avalanches are to be expected as the day progresses.
An unfavourable avalanche situation will be encountered over a wide area. Wet snow represents the main danger.
In the early morning as a consequence of warming during the day and solar radiation there will be a rapid increase in the danger of wet avalanches. Avalanches can in some places be released by a single winter sport participant. On very steep sunny slopes small and medium-sized moist loose snow avalanches are to be expected as the moisture increases. These can release the saturated snowpack and reach large size in isolated cases, in the regions exposed to a lot of new snow especially. Wet slab avalanches are to be expected in the afternoon, in particular on steep shady slopes between approximately 2200 and 2600 m. Especially here avalanches can be released in the weakly bonded old snow and reach large size in some cases. This also applies in isolated cases in highly frequented off-piste terrain. In steep gullies the avalanches can reach areas without any snow cover.
The fresh wind slabs can be released by a single winter sport participant in some cases, in particular adjacent to ridgelines and in gullies and bowls in high Alpine regions. Avalanches can in very isolated cases penetrate deep layers and reach large size.
Snowpack
dp.10: springtime scenario dp.1: deep persistent weak layer
The surface of the snowpack will cool hardly at all during the overcast night. Sunshine and high temperatures will give rise as the day progresses to increasing and thorough wetting of the snowpack below approximately 3000 m. The high humditiy will give rise in the afternoon to a loss of strength within the snowpack also on steep shady slopes. West, north and east facing slopes above approximately 2200 m: Towards its base, the snowpack consists of faceted crystals. 10 to 20 cm of snow, and even more in some localities, has fallen since Monday above approximately 2500 m. In high Alpine regions mostly small wind slabs formed.
Tendency
The surface of the snowpack will only just freeze and will soften quickly. As the day progresses as a consequence of warming during the day and solar radiation there will be an increase in the danger of wet avalanches.

The danger of moist and wet avalanches will already exist in the early morning. Increase in danger in the course of the day.
Moist and wet avalanches can be released by people, especially on very steep west, north and east facing slopes below approximately 2500 m. As the day progresses as a consequence of warming during the day and solar radiation there will be an increase in the danger of wet avalanches. Individual natural avalanches are possible. Especially on steep shady slopes avalanches can be released in the weakly bonded old snow and reach large size in isolated cases.
Individual avalanche prone locations for dry avalanches are to be found on very steep shady slopes above approximately 2500 m. Such avalanche prone locations are difficult to recognise. Especially transitions from a shallow to a deep snowpack are unfavourable.

An unfavourable avalanche situation will be encountered over a wide area. Wet snow represents the main danger.
In the early morning as a consequence of warming during the day and solar radiation there will be a rapid increase in the danger of wet avalanches. Most and wet avalanches can in some places be released by a single winter sport participant. Caution is to be exercised in particular on very steep slopes below approximately 2500 m. As the penetration by moisture increases the prevalence of the avalanche prone locations will increase as the day progresses. More frequent wet slab avalanches are to be expected in the afternoon. Caution is to be exercised in particular on steep shady slopes between approximately 2200 and 2600 m. Especially here wet avalanches can be released in the weakly bonded old snow and reach large size. This also applies in isolated cases in highly frequented off-piste terrain.

Individual avalanche prone locations for dry avalanches are to be found on very steep shady slopes above approximately 2600 m. Such avalanche prone locations are difficult to recognise. Especially transitions from a shallow to a deep snowpack are unfavourable. The small wind slabs are to be evaluated with care and prudence on near-ridge shady slopes in high Alpine regions.

During the night the weather was clear at times. Outgoing longwave radiation during the night was quite good at times. Sunshine and high temperatures will give rise as the day progresses to increasing and thorough wetting of the snowpack below approximately 3000 m. The high humditiy will give rise in the afternoon to a loss of strength within the snowpack also on steep shady slopes.

Wet snow
Wet snow represents the main danger.
Wet avalanches can in some places be released by a single winter sport participant. Avalanches can in isolated cases release the saturated snowpack and reach medium size. As the day progresses the likelihood of wet avalanches being released will increase a little.
Snowpack
dp.10: springtime scenario
The snowpack will be wet all the way through over a wide area. The surface of the snowpack will cool hardly at all during the overcast night and will already be soft in the early morning. In particular on steep sunny slopes as well as below approximately 1800 m only a little snow is now lying.
Tendency
The danger of wet avalanches will persist.
