Fresh wind slabs require caution. Weakly bonded old snow in particular on steep, rather lightly snow-covered shady slopes. Gliding avalanches and moist snow slides are possible.
As a consequence of new snow and a light to moderate southerly wind, visible wind slabs formed on Sunday in particular adjacent to ridgelines on northwest, north and northeast facing slopes. These can be released easily, but they will be small in most cases.

Weak layers in the old snowpack can be released in isolated cases and mostly by large additional loads in particular on little-used, rather lightly snow-covered shady slopes. Areas where the snow cover is rather shallow where hard layers are lying on a weakly bonded old snowpack are especially unfavourable. In very isolated cases the avalanches in these loacations are large.

As a consequence of warming during the day and solar radiation small gliding avalanches and moist snow slides are possible.

Apart from the danger of being buried, restraint should be exercised in particular in view of the danger of avalanches sweeping people along and giving rise to falls.
Snowpack

In particular from areas near the border with Benasque via the border with Ribagorça to the border with Pallars up to 10 cm of snow fell on Sunday above approximately 2000 m. The southerly wind has transported the new snow. High altitudes in shady places that are protected from the wind: The fresh wind slabs are lying on soft layers. In isolated cases various wind slab layers are lying on a weakly bonded old snowpack. This applies in particular on rather lightly snow-covered shady slopes and at elevated altitudes.

Sunny slopes: The surface of the snowpack has frozen to form a strong crust and will already soften in the late morning.

At low altitude from a snow sport perspective, in most cases insufficient snow is lying.
Tendency
The danger of dry slab avalanches will decrease. The danger of gliding avalanches and moist snow slides will persist.

Gliding snow

Weakly bonded old snow on steep, rather lightly snow-covered shady slopes. Gliding avalanches and moist snow slides on very steep sunny slopes.
Weak layers in the old snowpack can be released in isolated cases and mostly by large additional loads on steep, little used shady slopes. Areas where the snow cover is rather shallow where hard layers are lying on a weakly bonded old snowpack are especially unfavourable. Sometimes the avalanches in these loacations are medium-sized.

Gliding avalanches and moist snow slides are possible from the middle of the day. Most of the starting zones have released the snow entirely. Individual small natural avalanches are nontheless not entirely ruled out.

Apart from the danger of being buried, restraint should be exercised in particular in view of the danger of avalanches sweeping people along and giving 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.

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

At low altitude from a snow sport perspective, in most cases insufficient snow is lying.
Tendency
The avalanche danger will persist.
