"comment": "As the day progresses as a consequence of warming during the day and solar radiation there will be an appreciable increase in the danger of wet avalanches. Wet avalanches can in some places be released by a single winter sport participant. This applies on very steep shady slopes below approximately 2500 m, as well as on very steep sunny slopes at elevated altitudes. Natural avalanches are possible in the afternoon. Avalanches can be released in the weakly bonded old snow and reach large size in isolated cases.
Dry avalanches can additionally be released, even by small loads in isolated cases, especially on very steep northwest, north and northeast facing slopes above approximately 2500 m. Especially transitions from a shallow to a deep snowpack are unfavourable. The avalanche prone locations are difficult to recognise.",
