Moderate avalanche danger will prevail.
As the day progresses the likelihood of moist small and medium sized avalanches being released will increase in particular on steep slopes. The avalanche prone locations are to be found in particular at the base of rock walls, and adjacent to ridgelines and in gullies and bowls. The wind slabs are in isolated cases prone to triggering. Avalanches can be released, mostly by large loads. In many places there is a danger of falling on the hard snow surface.
The weather conditions have generally caused a reduction in the avalanche risk due to repeated cycles of melting and refreezing; nevertheless, the cooling is promoting a resumption of constructive metamorphism processes within the snowpack, leading to the formation of persistent weak layers that had been interrupted by the rise in temperatures. This process is occurring mainly where the snowpack is thinner. The weather conditions as the day progresses will give rise to moistening of the snowpack, in particular at low and intermediate altitudes. Weak layers exist in the snowpack in particular on shady slopes.
The weather will be cloudy. Light precipitation.
