Border Graie Alps

Weak layers in the lower part of the snowpack represent the main danger.

Weak layers in the lower part of the snowpack represent the main danger.

The avalanche prone locations are to be found in particular in steep terrain at high altitudes and in high Alpine regions and adjacent to ridgelines and in gullies and bowls, where weak layers exist in the old snowpack or where melt-freeze crusts have formed are unfavourable. This applies especially on wind-loaded slopes, and, in particular along the border with France. New snow and wind slabs can be released, even by small loads in isolated cases and reach medium size. In other regions the avalanche prone locations are more rare and the danger is lower.

Sunny slopes and low and intermediate altitudes: The snowpack is fairly homogeneous and its surface has a melt-freeze crust that is not capable of bearing a load. Especially shady slopes and in shady places that are protected from the wind: The snowpack is soft and has a loosely bonded surface. In addition clearly visible wind slabs formed adjacent to ridgelines and in gullies and bowls and in the high Alpine regions.
