The conditions are mostly favourable. Individual avalanche prone locations for dry avalanches are to be found in particular on extremely steep shady slopes at elevated altitudes.

Weak layers in the old snowpack can still be released in very isolated cases in little used terrain. The avalanche prone locations are to be found on extremely steep west, north and east facing slopes above approximately 2400 m. Caution is to be exercised in particular at transitions from a shallow to a deep snowpack, when entering gullies and bowls for example. Avalanches can reach medium size in isolated cases. The hard wind slabs are small and can only be released in isolated cases. Individual avalanche prone locations are to be found in particular on near-ridge shady slopes. They are easy to recognise. Restraint should be exercised because avalanches can sweep people along and give rise to falls. On extremely steep sunny slopes individual mostly small wet loose snow slides are possible as a consequence of warming during the day and solar radiation.
Faceted weak layers exist in the bottom section of the snowpack on west, north and east facing slopes. The mostly shallow wind slabs of the last few days have bonded quite well with the old snowpack. They can only be released in isolated cases. Steep sunny slopes: The snowpack is well consolidated and its surface has a crust that is barely capable of bearing a load. The solar radiation will give rise as the day progresses to gradual softening of the snowpack on steep sunny slopes. This also applies at low and intermediate altitudes in all aspects. Only a small amount of snow is lying for the time of year.
A generally favourable avalanche situation will prevail.
