Weakly bonded old snow is to be evaluated with care and prudence. As the day progresses, individual wet avalanches are possible.
Weak layers in the old snowpack can still be released in isolated cases by individual winter sport participants. This applies in particular at transitions from a shallow to a deep snowpack, when entering gullies and bowls for example, as well as in little used terrain. The avalanche prone locations are rare but are barely recognisable, even to the trained eye. They are to be found in particular on steep shady slopes above approximately 2000 m and on steep sunny slopes above approximately 2200 m. Avalanches can penetrate deep layers. Mostly they are medium-sized. As a consequence of warming during the day and the solar radiation, the likelihood of wet avalanches being released will increase gradually on very steep sunny slopes below approximately 2400 m. Meticulous route selection is advisable.

Outgoing longwave radiation during the night was good. The old snowpack remains prone to triggering in some places, in particular on steep shady slopes above approximately 2000 m, as well as on steep sunny slopes above approximately 2200 m. The snowpack will be subject to considerable local variations above the tree line. Sunshine and high temperatures will give rise as the day progresses to gradual softening of the snowpack, especially on steep sunny slopes.
Tendency
The avalanche danger will persist. The avalanche danger will increase a little during the day.
