Fresh wind slabs at high altitude.
Fresh wind slabs are in isolated cases prone to triggering. The avalanche prone locations are to be found on near-ridge north and west facing slopes above approximately 2400 m. The prevalence of avalanche prone locations and likelihood of triggering will increase with altitude. They are easy to recognise. Avalanches can reach medium size in isolated cases. 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 sunny slopes.
Shady slopes: As a consequence of a moderate wind from easterly directions, mostly small wind slabs formed on Monday adjacent to ridgelines on north and west facing slopes. They are lying on unfavourable layers in particular on steep shady slopes at elevated altitudes. Faceted weak layers exist deeper in the old snowpack on little used shady slopes. Sunny slopes: The solar radiation will give rise as the day progresses to moistening of the snowpack on steep sunny slopes.
The weather conditions will facilitate a gradual stabilisation of the snow drift accumulations.
