Avalanche Problem
Wind-drifted snow above the treeline, N-NE-E-SE-W-NW


In the last few days the wind slabs have increased in size once again. Wind slabs are to be evaluated critically. Even in moderately steep terrain there is a danger of falling on the hard crust.

The avalanche-prone wind slabs can be released easily, even by a single winter sport participant, in all aspects above approximately 1800 m, especially at their margins. They are easy for the trained eye to recognise but to be assessed critically, especially adjacent to ridgelines and in pass areas,, in isolated cases also in gullies and bowls, and behind abrupt changes in the terrain.

Snowpack

dp 6: cold, loose snow and wind

The snowpack will be generally stable. The northerly wind will transport the snow. The fresh and somewhat older wind slabs will form in particular adjacent to ridgelines and in gullies and bowls in all aspects and at elevated altitudes. These can be released in isolated cases in all aspects. In many cases wind slabs are lying on a hard crust, in particular below the tree line as well as on sunny slopes at intermediate and high altitudes.

Tendency

Low, level 1.

Fresh wind slabs require caution.

The fresh wind slabs represent the main danger, caution is to be exercised in particular on steep shady slopes as well as adjacent to ridgelines and in gullies and bowls. The number and size of avalanche prone locations will increase with altitude. Avalanches can be released, even by a single winter sport participant and reach medium size. In regions neighbouring those that are subject to danger level 3 (considerable) avalanche prone locations are more prevalent and the danger is greater.
A latent danger of gliding avalanches exists. Caution is to be exercised in areas with glide cracks.

Snowpack

dp 6: cold, loose snow and wind

In some localities up to 5 cm of snow. fell, in particular in the north. The strong wind has transported the fresh and old snow. In some cases wind slabs are lying on soft layers.

Tendency

The avalanche danger will persist.
