In sintesi

Wind slabs require caution.

Problemi valanghivi

  • Wind slab

    • Above 2,400 m
    Dimensione
    1

    Stability: poor · Frequency: few

Tendency

The weather conditions will facilitate a gradual stabilisation of the snow drift accumulations.

Avalanche Activity

Wind slabs require caution.

The more recent wind slabs are in isolated cases prone to triggering. The avalanche prone locations are to be found on near-ridge shady slopes above approximately 2400 m. In regions exposed to the foehn wind these avalanche prone locations are a little more prevalent. Wind slabs are mostly only small. The avalanche prone locations are easy to recognise. Weak layers in the old snowpack can still be released in very isolated cases. The avalanche prone locations are to be found in little used backcountry terrain above approximately 2200 m, especially on very steep shady slopes. As a consequence of warming during the day and the solar radiation, the likelihood of moist loose snow slides being released will increase a little on extremely steep south facing slopes.

Snowpack Structure

Shady slopes: As a consequence of a moderate southerly foehn wind, clearly visible wind slabs will form on Wednesday in particular in the regions exposed to the foehn wind. They are lying on unfavourable layers in particular on very steep shady slopes at elevated altitudes. Faceted weak layers exist deeper in the old snowpack on little used shady slopes. Sunny slopes: The snowpack will be in most cases well bonded. As a consequence of low temperatures and low relative humidity a crust will form on the surface during the course of the night. Sunshine and high temperatures will give rise as the day progresses to increasing softening of the snowpack. Below the tree line only a little snow is now lying.
