The new snow and wind slabs of the last few days must be evaluated with care and prudence.

The fresh wind slabs of the last few days can be released easily by a single winter sport participant. Avalanches can in some cases reach medium size. In high Alpine regions the avalanche prone locations are more prevalent. Avalanche prone locations are to be found in gullies and bowls, and behind abrupt changes in the terrain. The avalanche prone locations are to be found in particular on very steep shady slopes at elevated altitudes. The wind slabs are to be bypassed as far as possible. 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.
In very isolated cases weak layers exist in the old snowpack in particular on shady slopes. This applies on very steep slopes above approximately 2200 m.

Snowpack

dp.6: cold, loose snow and wind

Over a wide area 15 to 40 cm of snow, and even more in some localities, will fall until the evening above approximately 1800 m. The fresh and older wind slabs are barely recognisable because of the poor visibility. In some places new snow is lying on soft layers. The fresh snow as well as the wind slabs to be found in particular above approximately 1800 m can be released easily, or, in isolated cases naturally.
In very isolated cases weak layers exist in the old snowpack in particular on shady slopes. This applies on very steep slopes above approximately 2200 m.
In particular below the tree line only a little snow is lying.

Tendency

In some regions 10 to 20 cm of snow, and even more in some localities, will fall on Friday above approximately 1800 m. In addition further wind slabs will form in particular adjacent to ridgelines and in gullies and bowls during the night. Increase in avalanche danger as a consequence of the precipitation.

Avalanches can in some places be released, even by a single winter sport participant and reach medium size. The avalanche prone locations are to be found in particular on steep shady slopes and in gullies and bowls, and behind abrupt changes in the terrain. The number and size of avalanche prone locations will increase with altitude. Isolated small and medium-sized loose snow avalanches are possible as a consequence of the new snow.
In isolated cases avalanches can also release deeper layers of the snowpack, especially on very steep west, north and east facing slopes above approximately 2200 m.

Over a wide area 10 to 20 cm of snow, and even more in some localities, will fall until the evening above approximately 1800 m. In some places new snow is lying on soft layers. The fresh and older wind slabs are barely recognisable because of the poor visibility.
In very isolated cases weak layers exist in the old snowpack in particular on shady slopes. This applies on very steep slopes above approximately 2200 m. In particular below the tree line only a little snow is lying.

Tendency

Over a wide area 5 to 20 cm of snow will fall on Friday above approximately 1800 m. In addition further wind slabs will form in particular adjacent to ridgelines and in gullies and bowls during the night. Slight increase in avalanche danger as a consequence of the precipitation.

New snow and wind slabs require caution.

The fresh wind slabs can be released in isolated cases. The avalanche prone locations are to be found in particular on very steep shady slopes at elevated altitudes, especially at transitions into gullies and bowls. Mostly avalanches are only small. 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.

Snowpack

dp.6: cold, loose snow and wind

The fresh snow as well as the wind slabs to be found in particular above approximately 2000 m can be released easily, or, in isolated cases naturally. Soft wind slabs can be released easily especially at their margins. The fresh and older wind slabs are barely recognisable because of the poor visibility. In isolated cases wind slabs are lying on soft layers, in particular on steep shady slopes at elevated altitudes.
In particular below the tree line only a little snow is lying.

Tendency

Over a wide area wind and new snow above approximately 1800 m. Slight increase in avalanche danger as a consequence of the snowfall.
