Considerable avalanche danger will persist in some regions. Wind slabs require caution.
Snowpack
The snowdrift accumulations have stabilised over the past few days. Some are covered with a light layer of new snow and are difficult to recognise. Snow layering is mostly favourable north of the Rhône-Rhine line. Especially in the inneralpine regions of Valais and Grisons and on the southern flanks of the Alps, weak layers deep in the snowpack may still be released in some places. Below around 2200 m, layers of the snowpack that are near the ground are sometimes moist. This means that gliding avalanches are still to be expected. In many areas, there is about twice as much snow as there normally is at the beginning of December. Only on the southern flank of the Alps are snow depths below average.
