In all aspects a considerable avalanche danger will prevail. Natural avalanches are still possible in isolated cases.

Fresh snow and large quantities of wind-drifted snow remain for the foreseeable future prone to triggering. Medium-sized and, in isolated cases, large natural avalanches are possible in isolated cases. In the regions exposed to a lot of wind this applies in particular. The fresh snow of the weekend and the sometimes deep wind slabs can be released easily in all aspects and generally above the tree line. Remotely triggered avalanches are possible. The avalanche prone locations are sometimes covered with new snow and are difficult to recognise.
In the regions with a lot of snow gliding avalanches are possible, even quite large ones. This applies in particular at low and intermediate altitudes.
The conditions are precarious for snow sport activities. Caution and restraint are recommended.

Snowpack

dp.6: cold, loose snow and wind
dp.2: gliding snow

A lot of snow fell in the last few days over a wide area. The strong wind has transported the new snow. In some places new snow and wind slabs are lying on soft layers.
In its middle, the snowpack is unfavourably layered. Towards its base, the snowpack is largely stable.

Tendency

The avalanche danger will persist.

Wind slabs are to be evaluated with care and prudence.

Avalanches can in some cases be released in deep layers and reach large size in isolated cases, this also applies in areas close to the tree line, caution is to be exercised in areas where the snow cover is rather shallow, as well as at transitions from a shallow to a deep snowpack. Remotely triggered avalanches are possible.
As a consequence of new snow and a sometimes strong wind from variable directions, avalanche prone wind slabs formed in the last few days in particular in gullies and bowls and behind abrupt changes in the terrain. These can be released even by a single winter sport participant in all aspects and generally above the tree line. Mostly avalanches are medium-sized. The number and size of avalanche prone locations will increase with altitude.
Below the tree line the situation is more favourable.

Snowpack

dp.6: cold, loose snow and wind
dp.7: snow-poor zones in snow-rich surrounding

The strong wind has transported the new snow significantly. Over a wide area wind slabs are lying on old snow containing large grains. The old snowpack is faceted. Whumpfing sounds and stability tests confirm the unfavourable bonding of the snowpack.

Tendency

Hardly any decrease in avalanche danger. On Monday it will be cold.
