Snowpack Snowpack structure is unfavourable in many locations in southern Valais, Ticino and Grisons, with distinct weak layers that are prone to triggering in the middle and lower part of the snowpack. Whumpfing sounds and avalanches triggered by human activity, often remotely, continue to be reported from these regions. Snowpack structure is somewhat more favourable on the northern flank of the Alps and in northern Valais, but there are weak layers deeper in the snowpack in these regions too. These may still be triggered, especially where there is little snow and at transitions from a deep to shallow snowpack.
