Avalanche Problem
Wind-drifted snow above the treeline, N-NE-E-SE-S-SW-W-NW
Gliding snow above 2600m, N-NE-E-SE-S-SW-W-NW


Slight increase in avalanche danger as a consequence of the storm force northerly wind. The fresh wind slabs represent the main danger.

Even single winter sport participants can release avalanches easily, including dangerously large ones. The wind slabs are to be found in particular adjacent to ridgelines and in gullies and bowls in all aspects. The number and size of avalanche prone locations will increase with altitude, caution is to be exercised in the regions exposed to the foehn wind also below the tree line. In particular in the regions exposed to heavier precipitation and at high altitudes and in high Alpine regions individual medium-sized natural avalanches are possible as a consequence of the storm force northerly wind. The current avalanche situation calls for extensive experience in the assessment of avalanche danger and restraint.
Especially below approximately 2600 m small and medium-sized gliding avalanches and moist snow slides are possible.

Snowpack

dp 6: cold, loose snow and wind
dp 2: gliding snow

Some snow has fallen in particular in the north. The wind will be storm force over a wide area. The wind slabs have bonded poorly with the old snowpack. Faceted weak layers exist in the old snowpack in particular adjacent to ridgelines. The old snowpack will be moist below approximately 2200 m.

Tendency

Slight decrease in danger of dry avalanches. Slight increase in danger of gliding avalanches and moist snow slides as a consequence of warming.
