Southerly foehn wind is depositing snowdrifts distant from ridgelines
Avalanche danger above 1600m is considerable, below that altitude danger is low. Main danger stems from freshly generated trigger-sensitive snowdrift accumulations. Slab avalanches can be triggered by one sole skier in some places and grow to medium size, also naturally triggered avalanches are possible. Danger zones occur also distant from ridgelines, near forest rims, behind protruberances and in wind-loaded gullies and bowls on W/N/E facing slopes. As amounts of fresh snowfall increase, naturally triggered, mostly small loose-snow avalanches are likely. On shady steep slopes, fractures can in isolated cases penetrate down to more deeply embedded weak layers and the releases then grow to larger size. Caution urged in transitions from shallow to deep snow.
Snowpack
The fresh snowfall is being transported far-reachingly, deposited on shady slopes atop faceted expansively metamorphosed snowpack surfaces. In addition, blanketed fresh snow inside the masses of fresh fallen snow constitutes a weak layer. Apart from that the snowpack in wind-protected shady terrain is loosely packed. In wind-exposed terrain the snowpack surface is highly varied.
Tendency
Snowdrift accumulations remain prone to triggering

Caution: fresh snowdrifts
Avalanche danger above 1800m is moderate, below that altitude danger is low. Main danger stems from fresh snowdrifts. Slab avalanches of small-to-medium size can be triggered even by minimum additional loading on steep NW/N/E facing slopes. Danger zones occur near to ridgelines, behind protruberances and in gullies and bowls. Size and frequency of danger zones tend to increase with ascending altitude and as the day unfolds.
Snowpack
Fresh snow will be transported in wind-exposed terrain. Near-surface weak layers constitute a weak layer on shady slopes, as also does the blanketed fresh snow. Where rain transforms to snowfall the bonding between fresh snow and old snowpack is good. In generally, there is below average snow on the ground.
Tendency
The freshly generated snowdrifts will slowly settle.

Snowpack
Fresh snow will be deposited atop a compact base. Where the precipiation turns from rain to snowfall, bonding will be mostly good. Below average amounts of snow lie on the ground.
