On the Main Alpine Ridge from the Great St. Bernard to the Bernina Pass and southwards therefrom, wide-ranging snowdrift accumulations
have been generated at elevated altitudes over the course of the last week in the wake of large quantities of fresh snow accompanied
by storm-strength southerly winds. These snowdrifts are still prone to triggering in some places. In the northern regions,
generally small-sized snowdrift accumulations were generated on Tuesday during the nighttime hours as a result of the fresh
snow and northerly winds.
Below 2500 m the snow cover has been weakened due to intensive rainfall this week. On north-facing slopes below 2400 m more
than anywhere else, some large-sized and, in isolated cases, very large-sized wet-snow avalanches have been observed. As of
the termination of this period of precipitation and the subsequently dropping temperatures, activity of wet-snow avalanches
has diminished. During the nocturnal hours on Wednesday night, amid overcast skies, the moist snowpack surface at intermediate
and high altitudes will hardly be able to freeze. Isolated wet-snow and gliding avalanches continue to be possible.
In general, the Avalanche Warning Services have little information currently available from outlying regions. For that reason,
avalanche danger levels need to be examined especially carefully on-site.
