Avalanche Problem
Wind-drifted snow above 2400m, N-NE-E-SE-S-SW-W-NW

Wind slabs at high altitude. The number and size of avalanche prone locations will increase in the afternoon.

In the late morning a quite favourable avalanche situation will be encountered over a wide area. The older wind slabs of last week represent the main danger. Dry avalanches can in some cases be released by a single winter sport participant and reach medium size, especially on very steep slopes above approximately 2800 m in all aspects.
Gradual increase in danger of dry avalanches in the afternoon. As a consequence of fresh snow and wind, sometimes avalanche prone wind slabs will form. The avalanche prone locations are to be found in particular in gullies and bowls, and behind abrupt changes in the terrain above approximately 2400 m. The prevalence of avalanche prone locations and likelihood of triggering will increase with altitude. They are barely recognisable because of the poor visibility.
On steep grassy slopes snow slides are possible as a consequence of the fresh snow, in the regions exposed to heavier precipitation especially at low and intermediate altitudes.

Snowpack

dp 6: cold, loose snow and wind
dp 4: cold following warm / warm following cold

Faceted weak layers exist in the top section of the snowpack above approximately 2800 m.
Over a wide area 10 to 20 cm of snow, and even more in some localities, will fall in the afternoon above approximately 1000 m. The wind will transport the fresh snow significantly. Fresh wind slabs are lying on soft layers especially on steep shady slopes above approximately 2400 m.
The old snowpack will be wet all the way through at intermediate and high altitudes.

Tendency

Further increase in avalanche danger as a consequence of fresh snow and strong wind. Considerable, level 3.

Snowpack

dp 6: cold, loose snow and wind

Over a wide area 10 to 20 cm of snow, and even more in some localities, will fall in the afternoon above approximately 1000 m. The northwesterly wind will transport the fresh snow significantly. Fresh wind slabs are lying on soft layers especially on steep shady slopes above approximately 2400 m.
The old snowpack will be wet all the way through at intermediate and high altitudes.

Tendency

Increase in avalanche danger as a consequence of fresh snow and strong wind. Considerable, level 3.
