Snowpack structure (2026-03-18):
On wind-protected shady slopes, the weekend’s fresh snow is lying on surface hoar in some places. Loose fresh snow is additionally being transported by strong winds from variable directions resulting in the formation of snowdrift accumulations that are prone to triggering. Further small-scale snowdrift accumulations will form in Wednesday's strong southerly winds.In the inneralpine regions of Valais and Grisons, the layers of fresh and drifted snow are also lying on a weak old snowpack with pronounced near-ground weak layers. Avalanches can sometimes propagate into these deep weak layers or be triggered there directly in isolated cases. In other regions, weak layers in old near-ground snowpack still remain in places on shady slopes but are now mainly so thickly covered that they are largely insensitive to triggering.
