Border Graie Alps

The fresh and somewhat older wind slabs must be evaluated with care and prudence above the tree line.

The fresh and somewhat older wind slabs must be evaluated with care and prudence above the tree line.

As a consequence of a strong northwesterly wind, large wind slabs formed adjacent to ridgelines and in gullies and bowls as well as above the tree line. These can be released easily. or in isolated cases naturally, in particular on very steep northeast, east and southeast facing slopes. The avalanches can be released, even by a single winter sport participant. Additionally avalanches can also be released in deep layers and reach quite a large size. As a consequence of the solar radiation, the likelihood of natural moist avalanches being released will increase gradually in particular on rocky sunny slopes.

The strong wind has transported the loosely bonded old snow. The fresh and somewhat older wind slabs are poorly bonded with the old snowpack in particular on northeast, east and southeast facing slopes at intermediate and high altitudes. Faceted weak layers exist in the bottom section of the snowpack at high altitudes and in high Alpine regions. The weather conditions fostered a gradual settling of the snowpack in particular at low and intermediate altitudes. Sunshine and high temperatures will give rise as the day progresses to increasing moistening of the snowpack in particular on rocky sunny slopes.
