Snowpack structure (2026-03-19):
Near-surface layers on wind-protected shady slopes are lying on surface hoar in places. During the course of this week, snowdrift accumulations have formed in winds from varying directions, with Wednesday's strong winds being from the southeast. The snowdrift accumulations are particularly prone to triggering on shady slopes.In the inneralpine regions of Valais and Grisons, the layers of fresh and drifted snow are additionally 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.
