Snowpack structure (2026-02-22):
The large volumes of fresh and drifted snow from the last few days and weeks remains prone to triggering in many places.North of a line from the Rhone to the Rhine and in the extreme west of Lower Valais, 2 to 3.5 m of snow have fallen over the last two weeks. As a result, weak layers in the old snowpack are thickly covered and are now barely triggerable by human activity. However, avalanches can occasionally propagate into deep layers, becoming very large as a result.South of the line from the Rhone to the Rhine, the persistent weak layers are still pronounced. The weakly bonded old snow is most prone to triggering in Ticino and Grisons, where avalanche prone locations are still common, and whumpfing sounds and remote triggering are typical, even around the treeline. In southern Valais, the significant weak layers in the lower part of the snowpack are mostly rather more thickly covered. Avalanche prone locations where avalanches can be triggered in the old snowpack are therefore somewhat rarer and are mainly located in areas with thinner snow cover.With the mild temperatures, medium to large gliding avalanches are increasingly to be expected on steep grassy slopes below approximately 2000 m.
