Deferegger Alps East

Weakly bonded old snow at high altitudes and in high Alpine regions.

Weakly bonded old snow at high altitudes and in high Alpine regions.

In some places avalanches can be triggered in the weakly bonded old snow and reach medium size. The avalanche prone locations are to be found in all aspects at elevated altitudes, especially on very steep shady slopes above approximately 2000 m, as well as on very steep sunny slopes in high Alpine regions. Such avalanche prone locations are difficult to recognise. Caution is to be exercised at transitions from a shallow to a deep snowpack. The somewhat older wind slabs are mostly small and can only be released in isolated cases. As a consequence of new snow and a freshening wind, small wind slabs will form towards the evening in particular adjacent to ridgelines and in pass areas. Avalanche prone locations are to be found on very steep shady slopes.

5 to 10 cm of snow will fall from the afternoon. The snowpack will be subject to considerable local variations. Faceted weak layers exist in the old snowpack at elevated altitudes. Fresh and somewhat older wind slabs are lying on soft layers in particular on shady slopes at elevated altitudes.

Wind slabs and weakly bonded old snow require caution.
