At elevated altitudes, large quantities of the abundant fresh snow has been transported and deposited very irregularly. Only
the old snow cover remains on some ridges and peaks. In some instances, very large amounts of drifted snow is lying in bowls.
The fresh snow is settling, but only slowly because of the low temperatures. The bonding between the fresh snow and the old
snowpack is unfavourable on little used north facing slopes in particular, otherwise it is already quite good in some instances.
Fractures within the fresh snow and wind slab layers remain likely.
Isolated avalanches capable of reaching the valley bottom were observed on Tuesday, some of which were also registered by
the automatic detection systems.
Weak layers in the old snow near the ground persist in all aspects in particular in Valais and Grisons above approximately
2200 to 2400 m. Avalanche releases in these deep weak layers cannot be entirely ruled out where the fresh snow and snow drift
accumulations of recent days give rise to excessive loading.
