Persistent weak layers· Morning
- Above 2,000 m
Weakly bonded old snow is to be evaluated with care and prudence. Slight increase in danger of gliding avalanches as a consequence of warming during the day.

Weak layers in the old snowpack can be released in some places by individual winter sport participants. The avalanche prone locations are to be found in particular on very steep west, north and east facing slopes above approximately 2000 m and on very steep south facing slopes above approximately 3000 m. The wind slabs of the last few days can be released by a single winter sport participant in some cases in particular on near-ridge shady slopes at elevated altitudes. Individual medium-sized avalanches are possible. Meticulous route selection is advisable. As a consequence of warming individual gliding avalanches and moist snow slides are possible as the day progresses, but they will be mostly small. This applies in particular on very steep sunny slopes, as well as on cut and grassy slopes at low and intermediate altitudes.
The new snow and wind slabs of the last few days are lying on top of a weakly bonded old snowpack, especially on very steep west, north and east facing slopes above approximately 2000 m. The weather conditions as the day progresses will give rise to slight moistening of the snowpack at low and intermediate altitudes. This applies on steep sunny slopes. Only a small amount of snow is lying for the time of year.
Weakly bonded old snow represents the main danger. Small gliding avalanches and snow slides are possible as a consequence of warming.
