Weakly bonded old snow in particular on steep, rather lightly snow-covered shady slopes. Wind slabs from the middle of the day.
Weak layers in the old snowpack can be released in isolated cases and mostly by large additional loads in particular on steep, rather lightly snow-covered shady slopes. Transitions from a shallow to a deep snowpack where hard layers are lying on a weakly bonded old snowpack are especially unfavourable. In isolated cases the avalanches in these loacations are dangerously large.

As a consequence of new snow and a light to moderate southerly wind, soft wind slabs will form from the middle of the day in particular adjacent to ridgelines. The fresh wind slabs will form in particular in the east and in the south and generally at high altitudes. These can to an increasing extent be released easily, but they will be small in most cases.

The current avalanche situation calls for meticulous route selection. Even a small avalanche can sweep winter sport participants along and give rise to falls.
Snowpack
>
The snowpack is largely stable. High altitudes in shady places that are protected from the wind: Towards its surface, the snowpack is faceted. In isolated cases relatively hard layers of snow are lying on a weakly bonded old snowpack. In some cases the wind slabs have bonded still only poorly with each other and the old snowpack. This applies in particular on rather lightly snow-covered shady slopes and at elevated altitudes. Some snow will fall from early morning in particular from the border with Pallars via the border with Ribagorça to the border with Benasque. The southerly wind will transport only a little snow.

Intermediate altitudes and sunny slopes: The surface of the snowpack has frozen to form a strong crust and will hardly soften at all.

At low altitude from a snow sport perspective, in most cases insufficient snow is lying.
Tendency
Slight increase in danger of moist avalanches as a consequence of solar radiation. The danger of dry slab avalanches will persist.
