Persistent weak layers
- Above 2,200 m
Weakly bonded old snow requires caution. Wind slabs at elevated altitudes.
Weakly bonded old snow requires caution. Wind slabs at elevated altitudes.
In isolated cases avalanches can be triggered in the faceted old snow and reach medium size, especially on very steep shady slopes above approximately 2200 m, as well as on very steep east and west facing slopes above approximately 2400 m. Caution is to be exercised at transitions from a shallow to a deep snowpack. As the day progresses the likelihood of avalanches being released will increase a little. In addition the wind slabs of the last few days are capable of being triggered in isolated cases still, in particular on very steep slopes at elevated altitudes, and adjacent to ridgelines. On sunny slopes mostly small wet avalanches are to be expected as a consequence of warming during the day and solar radiation.
Faceted weak layers exist in the old snowpack, especially on shady slopes above approximately 2200 m, as well as on east and west facing slopes above approximately 2400 m. The wind slabs are in individual cases still prone to triggering above approximately 2400 m. Sunshine and high temperatures will give rise as the day progresses to increasing moistening of the snowpack. These conditions will bring about a gradual weakening of the snowpack in particular on steep sunny slopes.
Significant warming. Increase in danger of wet avalanches in the course of the day.
