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

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

Weak layers in the old snowpack can be released even now by winter sport participants, 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. The avalanches can be released in the weakly bonded old snow and reach medium size. Caution is to be exercised on little used northeast and east facing slopes. As the day progresses the likelihood of wet avalanches being released will increase, in particular on sunny slopes below approximately 2600 m. Backcountry tours should be concluded timely.

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. Outgoing longwave radiation during the night will be reduced in some case. The surface of the snowpack is frozen, but not to a significant depth and will soften during the day. These weather conditions will bring about a weakening of the snowpack as the day progresses.

The danger of dry avalanches will decrease gradually. As the day progresses as a consequence of warming during the day and solar radiation there will be only a slight increase in the danger of wet avalanches.
