Snowpack
Small avalanche accumulations are being generated from place to place. The snowdrift accumulations from the beginning of the week are still prone to triggering in some places. They are frequently blanketed over with fresher snowfall and thus, difficult to recognize. Fractures in more deeply embedded layers inside the snowpack are currently not likely.
As a result of solar radiation, loose-snow avalanches and moist-snow slides from the fresh fallen snow are possible.
