Avalanche Activity

Weakly bonded old snow is to be evaluated with care and prudence. Wet avalanches as the day progresses.

In some places 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 somewhat older wind slabs at elevated altitudes are capable of being triggered in isolated cases still. As a consequence of warming during the day and the solar radiation, the likelihood of wet avalanches being released will increase appreciably, in particular on sunny slopes below approximately 2800 m, as well as on shady slopes below approximately 2400 m. Backcountry tours should be concluded timely.

Snowpack Structure

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 2600 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.

Tendency

Increase in danger of wet avalanches in the course of the day.
