Snowdrifts and weak layers in old snow on shady slopes, slight daytime cycle of wet-snow avalanche activity
Fresh snow and snowdrift accumulations on shady wind-protected slopes often lie deposited atop surface hoar. Winter sports enthusiasts can trigger avalanches, particularly by large additional loading on very steep shady backcountry slopes. These avalanche prone locations occur most of all in spots where the snow is shallow and in transitions from shallow to deep snow. If avalnaches fracture down to deeper-down layers of the snowpack, they can in isolated cases grow to large size. During the course of the day, natural triggerings of small-sized wet-snow and glide-snow avalanches are possible, particularly on steep sunny slopes.
Snowpack
Above about 1500m there has been about 10cm of fresh fallen snow, in Verwall and in Sllvretta somewhat less, below that altitude there was rainfall. The fresh snow lies deposited on sunny slopes atop a barely frozen, generally softened up surface, on shady slopes frequently atop surface hoar or a hard rain crust. The mid-level part of the snowpack consists widespread of well settled, compact layers which on shady higher-altitude slopes cover a poorly-structured old snowpack fundament.
Tendency
Avalanche danger will increase far-reachingly starting at noon on Saturday, due to fresh snowfall and wind.

Snowdrifts on shady slopes, slight daytime cycle of wet-snow avalanche activity
Fresh snow and snowdrifts lie deposited atop surface hoar on a wind-protected, high-altitude shady slopes. Winter sports enthusiasts can trigger generally small-sized avalanches. Apart from being buried in snow masses, the risks of being swept along and forced to take a fall require special caution. During the course of the day, natural triggerings of small-sized wet-snow and glide-snow avalanches are possible, particularly on steep sunny slopes.
Snowpack
Above about 1500m there has been about 10-15cm of fresh snow regionally, below that altitude there was rainfall. The fresh-fallen snow lies deposited on sunny slopes atop a barely frozen, generally softened up surface, on shady slopes frequently atop surface hoar or a hard rain crust. The mid-level part of the snowpack consists widespread of well settled, compact layers which on shady higher-altitude slopes cover a poorly-structured old snowpack fundament. No triggerings in this weak layer of the snowpack were further registered at the Avalanche Warning Service headquarters last week.
Tendency
Avalanche danger will increase widespread starting at noon on Saturday, due to fresh snowfall and wind.
