Avalanche Problem
Wind slab

2200m

 

The sometimes new snow-covered wind slabs of Monday represent the main danger.
The somewhat older wind slabs must be evaluated with care and prudence in all aspects above approximately 2200 m. The avalanche prone locations are to be found in particular on wind-protected shady slopes. Mostly Explanation: "these" may only stand for "these avalanches" are small but in some cases easily released. At the border to Ribagorça and Pallars and at the border to Benasque the avalanche prone locations are more prevalent and larger. In particular these can in some cases reach medium size. As a consequence of new snow and a light to moderate wind from variable directions, further wind slabs formed on Wednesday adjacent to ridgelines in all aspects as well as at elevated altitudes. The fresh wind slabs are mostly very small but can in some cases be released easily.

In addition as the day progresses individual small gliding avalanches and moist snow slides are possible.

The somewhat older wind slabs are covered with new snow in some cases and therefore difficult to recognise. Apart from the danger of being buried, restraint should be exercised in view of the danger of avalanches sweeping people along and giving rise to falls. Off-piste activities call for meticulous route selection.
Snowpack
>
The somewhat older wind slabs are lying on weak layers in particular on wind-protected shady slopes above approximately 2200 m. The wind slabs have bonded poorly with the old snowpack. Released avalanches and field observations confirm poor snowpack stability on wind-loaded slopes. Some snow fell today. The moderate wind has transported only a little snow. The fresh wind slabs have formed in particular adjacent to ridgelines in all aspects and at elevated altitudes.

Above the tree line there are 10 to 50 cm of snow, and even more in some localities. At high altitudes and in high Alpine regions snow depths vary greatly, depending on the infuence of the wind. At low and intermediate altitudes from a snow sport perspective, insufficient snow is lying.
Tendency
Friday: Hardly any decrease in danger of dry avalanches on wind-loaded slopes. Significant decrease in danger of moist avalanches as the temperature drops.
