The very deep layers of fresh fallen snow and freshly generated snowdrifts which were unleashed in numerous places on Tuesday
and on Wednesday lie deposited on west-facing, north-facing and east-facing slopes atop an unfavourable, expansively metamorphosed
(faceted) weak layer. From the southern Valais over the northern Ticino as far as Grisons, furthermore, the entire snowpack
is often expansively metamorphosed (faceted). Avalanche triggerings by persons are easily possible in all regions, except
on the southern flank of the Alps. In the central and eastern sectors of the northern flank of the Alps, in the northern Valais
and in Grisons, numerous large-sized avalanches were triggered today either by persons or artificially (through explosives).
This delicate situation is expected to quiet down only incrementally, particularly on shady slopes.
At intermediate altitudes, gliding avalanches continue to be possible.
