AVALANCHE ACTIVITY:
Several avalanches in Austria, articles below. Net PicAvalanche Summary
Recent avalanche activity has been limited, following a pattern of human and explosives triggered small (size 1) releases; wind slabs where wind loading has occurred and loose dry where it hasn't.
Looking forward, expect progressively touchy conditions and increasing hazard with forecast new snow and wind. Along with the usual surface instabilities, concern for a recently buried weak layer is also rising in step with this active weather.
Snowpack Summary
25-40 cm of new snow, favouring the south of the region, is expected to accumulate by the end of the day on Saturday. This will add to 10-20 cm of recent snow sitting on firm, wind affected snow at upper elevations, on surface hoar in sheltered areas, on a melt-freeze crust below 1900 m, and on a sun crust on south-facing slopes.
A crust from early December may be found around 200 cm deep in the snowpack. In shallow rocky areas, recent test results suggest that it may still be possible to trigger this layer. In deeper snowpack areas it has shown no recent results and appears to be unreactive in these areas.
