Border Graie Alps

Individual avalanche prone locations for dry avalanches are to be found on very steep slopes above approximately 2100 m. Slight increase in danger as a consequence of warming during the day and solar radiation.

Weak layers in the old snowpack can be released in isolated cases and mostly by large additional loads. Caution is to be exercised in gullies and bowls, and behind abrupt changes in the terrain, as well as at transitions from a shallow to a deep snowpack, especially on very steep shady slopes along the border with France and along the border between Valais and Italy. The avalanches can be released in the faceted old snow and reach medium size. Gradual increase in danger of dry and moist avalanches as a consequence of warming, in particular on rocky sunny slopes, as well as at the base of rock walls.

The wind slabs are bonding only slowly with the old snowpack in particular on shady slopes above the tree line. Towards its base, the snowpack is faceted and weak. In particular steep sunny slopes as well as below approximately 1900 m: As a consequence of mild temperatures and solar radiation a crust formed on the surface during the last few days. Snow depths vary greatly, depending on the infuence of the wind. Adjacent to ridgelines and in pass areas at elevated altitudes hardly any snow is lying.

As a consequence of rising temperatures and the mostly light wind, the snow drift accumulations stabilised during the last few days.
