Snowpack
With a southerly wind and some fresh snow, wind slabs developed at altitude, some of which are prone to triggering.
Avalanches can still occasionally be triggered in the old snowpack. This affects those slopes where there was already snow before last week’s precipitation: northern slopes above 2800 m and in the high Alpine regions in general.
Gliding avalanches are still possible on steep grassy slopes; these may be medium sized in the west and north.
