"comment": "As a consequence of warming during the day and solar radiation there will be only a slight increase in the danger of wet avalanches. Wet avalanches can in isolated cases be released by a single winter sport participant, especially on very steep sunny slopes especially above approximately 2500 m, this also applies on very steep shady slopes below approximately 2500 m in gullies and bowls. In isolated cases avalanches are medium-sized.
As a consequence of warming during the day and the solar radiation, the likelihood of slab avalanches being released will increase gradually on very steep sunny slopes at high altitudes and in high Alpine regions, in the regions exposed to a lot of new snow especially. Moist loose snow avalanches are to be expected as the day progresses, even medium-sized ones.
Weak layers in the old snowpack can be released in isolated cases and mostly by large additional loads in particular on very steep shady slopes, in particular above approximately 2500 m.",
