Sometimes heavy snowfall and strong wind gave rise to extensive snow drift accumulations on Monday and Tuesday on the northern
flank of the Alps and in Lower Valais in particular. In some places, these can still be released easily. Individual natural
avalanches are possible, in particular on very steep sunny slopes. From southern Valais through northern Ticino to Grisons,
weak layers exist in the old snowpack. Here, avalanches can be released in deep layers of the snowpack and reach a large size.
As a consequence of warming, gliding avalanches can occur in particular on the northern flank of the Alps at intermediate
altitudes.
