After the melt-freeze crust (capable of bearing loads) softens iup, also naturally triggered wet-snow avalanches are possible. Caution urged particularly towards steep shady slopes at 2200-2500m which have not yet discharged and slopes in all aspects where there is area-wide snow on the ground. Avalanches can fracture in weak old snowpack layers, in isolated cases grow to large size and lay back huge runout zones, quite atypically. Backcountry tours and ascents to refuges need to be launched early in the day and brought to an end early.",
