Avalanche Activity

The wind slabs of the last few days must be evaluated with care and prudence on steep shady slopes. From the middle of the day, wet avalanches are to be expected.

The wind slabs can be released by a single winter sport participant on steep shady slopes and above the tree line. The avalanche prone locations are to be found especially in gullies and bowls, and behind abrupt changes in the terrain and in the vicinity of peaks. In many cases the avalanches are medium-sized. Midday and afternoon: From the middle of the day the likelihood of moist and wet avalanches being released will increase quickly on steep sunny slopes in all altitude zones. Small and medium-sized natural avalanches are to be expected. Gliding avalanches can also occur. Backcountry touring and other off-piste activities call for extensive experience in the assessment of avalanche danger and careful route selection.

Snowpack Structure

The weather will be sunny. The fresh snow and in particular the sometimes deep wind slabs are lying on the unfavourable surface of an old snowpack. Faceted weak layers exist in the bottom section of the snowpack in particular on shady slopes. Sunshine and high temperatures will give rise from the middle of the day to increasing moistening of the snowpack especially on steep sunny slopes. There is more snow than usual. At intermediate altitudes there are 150 to 220 cm of snow, and even more in some localities.

Tendency

Monday: The avalanche danger will persist.
