Weak layers in the upper part of the snowpack can be released easily by individual winter sport participants in gullies and bowls and behind abrupt changes in the terrain. Avalanches can release deeper layers of the snowpack and reach medium size in particular along the border with Slovenia. This applies especially on west, north and east facing slopes above approximately 1800 m. The number and size of avalanche prone locations will increase with altitude. They are barely recognisable. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack indicate the danger.
In particular along the border with Slovenia 5 to 15 cm of snow, and even more in some localities, will fall above approximately 1200 m. As a consequence of a gusty southerly wind, soft wind slabs will form in the course of the day in gullies and bowls and behind abrupt changes in the terrain. These will be deposited on surface hoar in particular on wind-protected shady slopes. The old snowpack is faceted and weak.
The avalanche conditions remain unfavourable. As a consequence of new snow and wind the wind slabs will increase in size. The weather report and anticipated change in the avalanche danger are uncertain.
