Weak layers in the old snowpack necessitate caution.
Weak layers in the old snowpack necessitate caution.
Avalanches can in some places be released in the weakly bonded old snow, in particular by large additional loads, especially on very steep west, north and east facing slopes between approximately 2200 and 2600 m. Caution is to be exercised at transitions from a shallow to a deep snowpack, when entering gullies and bowls for example. Mostly avalanches are medium-sized. They can in very isolated cases reach large size. In addition the fresh wind slabs at elevated altitudes are prone to triggering in some cases. Adjacent to ridgelines and in gullies and bowls the avalanche prone locations are more prevalent. They are easy to recognise.
In its middle, the snowpack is faceted and weak, especially on shady slopes between approximately 2200 and 2600 m. Snow profiles and stability tests confirm this situation. Some snow will fall in some regions. As a consequence of the occasionally strong northerly wind, fresh snow drift accumulations will form on Saturday. These are poorly bonded with the old snowpack especially on wind-protected shady slopes, in particular at elevated altitudes.
The avalanche danger will persist.
