Caution, risk of spillage!
The avalanche risk is considerable above the tree line and moderate below it. The problem is wind slab avalanches at all altitudes. Slab avalanches can easily be triggered in blown-in areas, especially on steep slopes with aspects from north-west to east to south and in gullies and bowls with little additional load. Avalanche prone locations can also be found in forest transition areas, forest aisles and clearings. Avalanches can also become large in isolated cases.
With stormy westerly winds and snowfall, snowdrift accumulations continue to grow. Fresh and older wind slab lies on soft layers or surface hoar and is very prone to triggering. In places, weak intermediate layers are embedded in the new snow pack. At higher altitudes, deeper layers often consist of faceted crystals. The snow depth varies greatly, alternating between blown and drifted snow.
The avalanche situation remains critical for the time being.
