Wet avalanches can in isolated cases 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. <br/> <br/> Individual avalanche prone locations for dry avalanches are to be found on very steep shady slopes above approximately 2500 m.
