Avalanche Activity

In the afternoon as a consequence of new snow and wind there will be an increase in the avalanche danger. Backcountry touring calls for restraint.

As a consequence of low temperatures, snowfall and the moderate southeasterly wind, an unfavourable avalanche situation will develop in the afternoon. The fresh wind slabs can be released by a single winter sport participant. These avalanche prone locations are to be found in particular adjacent to ridgelines and in gullies and bowls, and behind abrupt changes in the terrain. They are barely recognisable because of the poor visibility. Backcountry touring calls for experience in the assessment of avalanche danger and careful route selection. Natural avalanches: Medium-sized and, in isolated cases, large dry loose snow avalanches are possible in particular from starting zones at higher altitudes.

Snowpack Structure

15 to 30 cm of snow has fallen since Sunday above approximately 1500 m. 25 to 40 cm of snow, and even more in some localities, will fall until Tuesday above approximately 1500 m. From Tuesday afternoon: The easterly wind will transport the new snow. The fresh snow and the wind slabs are bonding poorly with the old snowpack. The old snowpack is favourably layered. Snow depths vary greatly at high altitudes and in high Alpine regions, depending on the infuence of the wind.

Tendency

Some snow will fall on Wednesday. The danger will persist.
