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 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 extremely steep northeast and east facing slopes. As the day progresses the likelihood of wet avalanches being released will increase, in particular on steep east, south and west facing slopes below approximately 2400 m, as well as on steep shady slopes below approximately 2000 m. In some places avalanches can release the wet snowpack and reach quite a large size. This applies especially on steep east facing slopes. 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 already soften in the late morning. These weather conditions will bring about a gradual weakening of the snowpack.
Outgoing longwave radiation during the night will be reduced in some case. As the day progresses as a consequence of warming during the day and solar radiation there will be an increase in the danger of wet avalanches.
