Weakly bonded old snow is to be evaluated with care and prudence. Increase in danger of wet avalanches as a consequence of warming during the day.

Weak layers in the old snowpack can still be released in some places by individual winter sport participants, especially on steep, little used slopes above approximately 2200 m. Caution is to be exercised in particular at transitions from a shallow to a deep snowpack, when entering gullies and bowls for example. Mostly avalanches are medium-sized. The older wind slabs are in individual cases still prone to triggering in particular on very steep shady slopes. As a consequence of warming during the day, the likelihood of wet avalanches being released will increase in particular on steep sunny slopes below approximately 2600 m. Backcountry touring calls for meticulous route selection.

The old snowpack remains prone to triggering in some places, especially on steep, little used shady slopes above approximately 2200 m, as well as on sunny slopes above approximately 2500 m. The weather conditions brought about a slow strengthening of the old snowpack. The snowpack will be subject to considerable local variations. Sunshine and high temperatures will give rise as the day progresses to softening of the snowpack in particular on steep sunny slopes below approximately 2600 m.

As the day progresses as a consequence of warming there will be an increase in the danger of wet avalanches.
