Avalanche Problem

Wet snow above 2200m, N-NE-E-SE-S-SW-W-NW

Wind slabs are to be evaluated with care and prudence. The avalanche prone locations are sometimes covered with fresh snow and are barely recognisable because of the poor visibility.

The backcountry touring conditions in the morning are mostly favourable. In the afternoon as a consequence of the precipitation there will be a gradual increase in the danger of dry and moist avalanches. On wind-loaded slopes and from starting zones at higher altitudes individual natural avalanches are possible, in particular medium-sized ones. Single skiers can release avalanches in isolated cases, including large ones. The avalanche prone locations are to be found in particular on wind-loaded slopes of all aspects and in gullies and bowls in all aspects above approximately 2400 m. Also slopes adjacent to ridgelines are especially precarious. These avalanche prone locations are sometimes covered with fresh snow and are barely recognisable because of the poor visibility. Backcountry touring calls for experience in the assessment of avalanche danger and careful route selection.

Snowpack

10 to 20 cm of snow, and even more in some localities, will fall from early morning above approximately 1600 m. As a consequence of northwesterly wind, large surface-area wind slabs will form in particular adjacent to ridgelines. The wind slabs are lying on soft layers in particular on steep shady slopes above approximately 2400 m. The old snowpack remains moist below approximately 2200 m. Isolated avalanche prone weak layers exist in the bottom section of the snowpack especially in shady places that are protected from the wind.

Tendency

Gradual increase in avalanche danger as a consequence of fresh snow and strong wind.

The number and size of avalanche prone locations will increase in the afternoon.

In the late morning a quite favourable avalanche situation will be encountered over a wide area. The older wind slabs of last week represent the main danger. Slight increase in danger of dry avalanches in the afternoon. The prevalence of avalanche prone locations and likelihood of triggering will increase with altitude. They are barely recognisable because of the poor visibility.
On steep grassy slopes snow slides are possible as a consequence of the fresh snow, in the regions exposed to heavier precipitation especially at low and intermediate altitudes.

Snowpack

dp 6: cold, loose snow and wind

Over a wide area 10 to 15 cm of snow, and even more in some localities, will fall in the afternoon above approximately 1000 m. The old snowpack will be wet all the way through at intermediate and high altitudes.

Tendency

Increase in avalanche danger as a consequence of fresh snow and strong wind.
