"comment": "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. 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. Small and medium-sized natural avalanches are possible in the afternoon.
Individual avalanche prone locations for dry avalanches are to be found on very steep shady slopes above approximately 2500 m. Especially transitions from a shallow to a deep snowpack are unfavourable. The avalanche prone locations are difficult to recognise.",
