New snow and snowdrifts from the last few days lie deposited atop an unfavourable old snowpack surface in many places and
are prone to triggering from place to place. Beneath them the snowpack layering in the Jura region, on the northern flank
of the Alps and in the western part of the Lower Valais is predominantly favourable. Only in those areas of the rain crust
which formed at the end of December are there in places faceted, soft layers evident which in isolated cases are still prone
to triggering.
From the central part of the Valais over the northern Ticino as far as Grisons, the entire snowpack is often expansively metamorphosed
(faceted) and riddled with thin melt-freeze crusts. In places there, the snow is shallow, you sink down to the ground. In
the furthermost southern regions there is very little snow on the ground.
