Wind slab

Wet snow represents the main danger. Fresh wind slabs in the high Alpine regions.

Wet avalanches can as before be released by a single winter sport participant. The avalanche prone locations are to be found especially on very steep west, north and east facing slopes below approximately 2800 m. Avalanches can release the saturated snowpack and reach medium size. As a consequence of warming during the day there will be only a slight increase in the danger of wet avalanches. Individual gliding avalanches can also occur, caution is to be exercised in particular on very steep grassy slopes in the regions with a lot of snow.

In high Alpine regions small to medium-sized moist loose snow avalanches are possible. In the event of prolonged bright spells this applies in particular on extremely steep sunny slopes.

The fresh and somewhat older wind slabs can be released by a single winter sport participant in particular on very steep shady slopes above approximately 2800 m. Such avalanche prone locations are to be found in gullies and bowls, and behind abrupt changes in the terrain. In particular in high Alpine regions the avalanche prone locations are more widespread and the danger is greater.

Snowpack

dp.10: springtime scenario
dp.6: cold, loose snow and wind

The rain gave rise to a loss of strength within the snowpack. Already many wet avalanches have been released in particular on very steep west, north and east facing slopes. The snowpack will be wet all the way through. This applies on shady slopes below approximately 2600 m, as well as on sunny slopes below approximately 3000 m. On steep sunny slopes as well as at low and intermediate altitudes only a little snow is now lying. The surface of the snowpack will cool hardly at all during the overcast night and will already be soft in the early morning.

High Alpine regions: Over a wide area 20 to 60 cm of snow, and even more in some localities, fell in the last few days. As a consequence of new snow and a strong to storm force wind from southeasterly directions, extensive wind slabs formed. These are lying on soft layers on steep shady slopes. The weather effects will foster a rapid strengthening of the snow drift accumulations.

Tendency

The surface of the snowpack will cool hardly at all during the overcast night and will already be soft in the early morning. Wet snow requires caution.

At elevated altitudes individual mostly small moist loose snow avalanches are possible. In the event of prolonged bright spells this applies in particular on extremely steep sunny slopes.

Tendency

The surface of the snowpack will freeze very little and will soften quickly. Wet snow requires caution.

Wind slab
2400m


Wind slabs and wet snow represent the main danger. The new snow and wind slabs of the last few days must be evaluated with care and prudence above approximately 2400 m.

The conditions are unfavourable for backcountry touring. The more recent wind slabs can be released by a single winter sport participant in some cases in particular on very steep west, north and east facing slopes above approximately 2400 m. Such avalanche prone locations are to be found in particular adjacent to ridgelines and in gullies and bowls.
In particular on very steep slopes and below approximately 2600 m numerous medium-sized and, in isolated cases, large moist and wet avalanches are possible as the moisture increases. In particular on very steep west, north and east facing slopes medium-sized to large moist and wet avalanches are to be expected.
In isolated cases, the avalanches can reach areas without any snow cover in steep gullies.

Snowpack

dp.6: cold, loose snow and wind
dp.3: rain

The rain gave rise to increasing and thorough wetting of the snowpack below approximately 2200 m. This situation will give rise to a loss of strength within the snowpack in particular on steep slopes.
In some regions 40 to 100 cm of snow, and even more in some localities, fell in the last few days above approximately 2400 m. As a consequence of new snow and a sometimes strong southerly wind, sometimes avalanche prone wind slabs formed in particular adjacent to ridgelines and in gullies and bowls.

Tendency

Slight decrease in danger of wet avalanches as a consequence of the ceasing of precipitation. The surface of the snowpack will cool hardly at all during the overcast night will already be soft in the early morning. Wet snow represents the main danger. The new snow and wind slabs must be evaluated with care and prudence in high Alpine regions.


Danger level

2000m
Avalanche Problem
Wet snow
2000m


Wet snow represents the main danger.

As the penetration by moisture increases individual wet avalanches are possible, but they will be mostly small. At the base of rock walls and behind abrupt changes in the terrain and adjacent to ridgelines and in gullies and bowls medium-sized and, in isolated cases, large wet loose snow avalanches are possible above approximately 1800 m.

Snowpack

dp.3: rain

A lot of rain has fallen. The rain gave rise to increasing moistening of the snowpack. The snowpack will be wet all the way through over a wide area. Below approximately 1800 m a little snow is lying.

Tendency

Wet snow requires caution.

Gliding snow

Increase in danger of wet and gliding avalanches as a consequence of warming during the day and solar radiation.

Wet avalanches can in some cases be released by a single winter sport participant. The avalanche prone locations are to be found especially on very steep west, north and east facing slopes at high altitude. Avalanches can release the saturated snowpack and reach medium size in isolated cases.

Individual gliding avalanches can also occur. Such avalanche prone locations are to be found in particular on very steep grassy slopes. Areas with glide cracks are to be avoided as far as possible.

Snowpack

dp.10: springtime scenario
dp.2: gliding snow

The snowpack will be wet all the way through. This applies on shady slopes below approximately 2400 m, as well as on sunny slopes in all altitude zones. On steep sunny slopes as well as at low and intermediate altitudes only a little snow is now lying.

Tendency

During the night the weather will be clear at times. At high altitudes and in high Alpine regions the snowpack will freeze and form a strong crust. The surface of the snowpack will soften during the day. In the regions where the outgoing longwave radiation during the night is reduced the danger will increase more quickly.

Increase in danger of wet avalanches as a consequence of warming during the day and solar radiation.

As a consequence of warming during the day and solar radiation there will be a gradual increase in the danger of wet avalanches. Wet avalanches can in some places be released by a single winter sport participant. The avalanche prone locations are to be found especially on very steep west, north and east facing slopes below approximately 2800 m. Avalanches can release the saturated snowpack and reach medium size. Individual gliding avalanches can also occur, caution is to be exercised in particular on very steep grassy slopes in the regions with a lot of snow.

Fresh wind slabs can be released in isolated cases on very steep shady slopes in high Alpine regions. This applies especially in the south.

dp.2: gliding snow

The snowpack will be wet all the way through over a wide area. This applies on shady slopes below approximately 2600 m, as well as on sunny slopes below approximately 3000 m. Already many wet avalanches have been released in particular on very steep west, north and east facing slopes. On steep sunny slopes as well as at low and intermediate altitudes only a little snow is now lying. As a consequence of low temperatures the snowpack will consolidate during the course of the night.

In high Alpine regions mostly shallow wind slabs formed. The weather effects will bring about a substantial strengthening of the snow drift accumulations.

Tendency

During the night the weather will be clear at times, especially in the north. The surface of the snowpack will soften during the day. In the regions where the outgoing longwave radiation during the night is reduced the danger will increase more quickly.


Danger level



Low avalanche danger will prevail.

Only isolated wet avalanches are possible.

Snowpack

Outgoing longwave radiation during the night will be severely restricted. The surface of the snowpack will cool hardly at all during the overcast night and will already be soft in the early morning. The snowpack will be wet all the way through.
Only a little snow is now lying.

Tendency

Only isolated wet avalanches are possible.
