Avalanches can in some cases be released in the old snowpack and reach large size in isolated cases. The avalanche prone locations are to be found in particular on little used shady slopes above approximately 2200 m and on very steep west facing slopes above approximately 2400 m. The avalanche prone locations are barely recognisable, even to the trained eye. In some cases avalanches can release the moist old snow as well. Fresh wind slabs can be released easily in some places in particular on very steep shady slopes above approximately 2400 m. The avalanche prone locations are to be found in particular in gullies and bowls, and behind abrupt changes in the terrain. The number and size of avalanche prone locations will increase with altitude. The wind slabs are clearly recognisable to the trained eye. Avalanches can reach medium size. On steep grassy slopes and below approximately 2400 m small and medium-sized gliding avalanches are possible as a consequence of the new snow. This applies in the regions exposed to heavier precipitation in the south. Areas with glide cracks are to be avoided as far as possible. Small to medium-sized loose snow avalanches are possible, in the event of solar radiation especially on extremely steep sunny slopes.
As a consequence of a sometimes strong wind from northerly directions, wind slabs will form on Monday especially in gullies and bowls and behind abrupt changes in the terrain. The fresh wind slabs will be deposited on soft layers especially on shady slopes at elevated altitudes. Avalanche prone weak layers exist deeper in the snowpack especially on little used shady slopes. The old snowpack will be moist at low and intermediate altitudes. The high humditiy gave rise to moistening of the snowpack in some cases also at high altitude.
The weather conditions will facilitate a gradual settling of the snowpack.
