The conditions are mostly favourable. Avalanches can in very isolated cases be released in the old snowpack.
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. Wind slabs are small 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. Midday and afternoon: As a consequence of warming during the day and the solar radiation, the likelihood of wet loose snow avalanches being released will increase a little on extremely steep sunny slopes. Individual natural loose snow slides are to be expected. Restraint should be exercised because avalanches can sweep people along and give rise to falls.
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 are unlikely to be released now. 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 significant 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.
