It is especially on these aspects and at these critical altitudes that isolated large or occasionally even very large wet slab avalanches may be triggered naturally. In Grisons in particular, the weak layers in the old snowpack are the least deeply buried, and it is here that wet slab avalanches are likely also to be triggered by human activity. Whumpfing sounds continue to be a possible indication of a weak snowpack.
At higher altitudes, where the snowpack is still dry, the weak layers in the old snowpack must continue to be assessed with caution. However, dry avalanches have been rare in recent days.
