Fresh wind slabs require caution.

The fresh wind slabs must be evaluated with care and prudence in all aspects above the tree line. They are mostly easy to recognise but can be released easily. In the regions exposed to heavier precipitation caution is to be exercised in particular in gullies and bowls, and behind abrupt changes in the terrain. At high altitudes and in high Alpine regions avalanche prone locations are more prevalent. As a consequence of warming during the day and solar radiation individual gliding avalanches are possible, but they can reach medium size, especially at the base of rock walls and on steep grassy slopes below approximately 2400 m. Areas with glide cracks are to be avoided as far as possible.

Snowpack

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

The wind has transported only a little snow. The fresh wind slabs are clearly recognisable to the trained eye. These are lying on soft layers in particular on shady slopes above the tree line. The older wind slabs have bonded quite well with the old snowpack.
The old snowpack will be moist below the tree line.

Tendency

Moderate, level 2. Temporary increase in danger of gliding avalanches and snow slides as a consequence of warming during the day and solar radiation.

Danger level
Danger Level 1 - Low
Avalanche Problem
Wind-drifted snow above the treeline, N-NE-E-SE-S-SW-W-NW
Gliding snow above 2100m, SE-S-SW-W


Wind slabs at high altitude. Slides can occur on steep grassy slopes.

Individual avalanche prone locations for dry avalanches are to be found in particular adjacent to ridgelines and in pass areas. Such avalanche prone locations are rare and are easy to recognise. The mostly small wind slabs can be released, especially by large additional loads, in all aspects above the tree line. Even in moderately steep terrain there is a danger of falling on the hard snow surface, after a clear night in particular. As a consequence of warming during the day and solar radiation individual gliding avalanches and moist snow slides are possible, but they will be mostly small.

Snowpack

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

The snowpack will be in most cases stable. Over a wide area fresh snow and wind slabs are lying on a hard crust. At low and intermediate altitudes hardly any snow is lying.

Tendency

Low, level 1. Temporary increase in danger of gliding avalanches and snow slides as a consequence of warming during the day and solar radiation.
