As a consequence of fresh fallen snow and winds, snowdrift accumulations are being further generated particularly at high
altitudes. They are prone to triggering.
Below approximately 1800 to 2200 m, the snowpack has been moistened from the rainfall, thus, increasingly frequent naturally
triggered avalanches can be expected. Due to the unfavourable snowpack layering, these releases can fracture down to more
deeply embedded layers inside the snowpack, particularly on shady slopes in the western sector of the northern flank of the
Alps.
From the southern Valais over the northern Ticino as far as Grisons, equally pronounced weak layers are evident inside the
old snowpack. Particularly in seldom-frequented west-facing, north-facing and east-facing slopes, avalanches can be triggered
in these deeply embedded layers inside the snowpack, in isolated cases also large-sized releases.
