Avalanche Problem
Wind-drifted snow above the treeline, N-NE-E-SE-S-SW-W-NW


Slight increase in danger as a consequence of the snowfall.

As a consequence of fresh snow and a strong southwesterly wind, further wind slabs will form as the day progresses, in particular in gullies and bowls, and behind abrupt changes in the terrain at high altitudes and in high Alpine regions in all aspects. Even single winter sport participants can release avalanches, including large ones. The avalanche prone locations are barely recognisable because of the poor visibility.
Avalanches can in isolated cases be released in the old snowpack. Weak layers in the old snowpack can be released in isolated cases in particular at transitions from a shallow to a deep snowpack. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack indicate the danger.

Snowpack

dp 6: cold, loose snow and wind

Over a wide area 5 to 10 cm of snow. will fall. The strong wind will transport the snow. The fresh snow and wind slabs are lying on soft layers in all aspects. In some cases the various wind slabs have bonded still only poorly with each other and the old snowpack. The snowpack will be subject to considerable local variations. Large-grained weak layers exist in the old snowpack in particular on steep shady slopes.

Tendency

Slight increase in danger of moist avalanches as a consequence of solar radiation.

Tendency

As the snowfall becomes more intense the prevalence and size of the avalanche prone locations will increase during the course of the night. Friday: Slight increase in danger of moist avalanches as a consequence of solar radiation.

Wind slabs at high altitude. Wet and gliding snow require caution.

As a consequence of a moderate to strong wind from southerly directions, mostly small wind slabs will form. The somewhat older wind slabs of the last few days remain in some cases prone to triggering in particular on very steep shady slopes above approximately 2200 m. The fresh and somewhat older wind slabs can be released by a single winter sport participant in some cases. The avalanche prone locations are to be found in particular adjacent to ridgelines and in gullies and bowls in northwest to north to northeast facing aspects. At elevated altitudes the avalanche prone locations are more prevalent. In the regions neighbouring those that are subject to danger level 3 (considerable) and in the regions exposed to heavier precipitation the avalanche danger is higher.
In addition there is a danger of gliding avalanches and moist snow slides. This applies in particular on steep sunny slopes and on steep grassy slopes.

Snowpack

dp 6: cold, loose snow and wind
dp 3: rain

The wind slabs of the last few days have settled a little. Some snow will fall from the afternoon in particular along the border with Vorarlberg and along the border with South Tyrol,, also in the Schober Mountains and in the Glockner Range. The southerly wind will transport the fresh and old snow. Low and intermediate altitudes: Some rain will fall in some localities. The snowpack will be subject to considerable local variations.
Outgoing longwave radiation during the night will be severely restricted over a wide area.

Tendency

Slight increase in avalanche danger as a consequence of the precipitation.
