Danger level
Danger Level 3 - Considerable above the treeline
Danger Level 2 - Moderate above the treeline
Avalanche Problem
Wind-drifted snow above the treeline, N-NE-E-SE-S-SW-W-NW
Wet snow above the treeline, N-NE-E-SE-S-SW-W-NW

Increase in danger of dry avalanches as a consequence of fresh snow and stormy weather.

As a consequence of the snowfall, the likelihood of dry avalanches being released will increase appreciably especially above the tree line. Especially in places where the wind is storm force the avalanche danger is greater. The number and size of avalanche prone locations will increase as the day progresses. The avalanche prone locations are to be found in particular on wind-loaded slopes of all aspects. They will increase with altitude. The brittle wind slabs will be covered with fresh snow in some cases and therefore difficult to recognise.
In addition as the day progresses still more individual wet and gliding avalanches are possible. This applies in particular in starting zones below the tree line that have retained the snow thus far.

Snowpack

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

Over a wide area persistent snowfall to low altitudes. 30 to 50 cm of snow. will fall. The northwesterly wind will transport the fresh snow significantly. As a consequence of fresh snow and a storm force to violent wind from northwesterly directions, brittle wind slabs will form in all aspects. These will be deposited on soft layers.

Tendency

The avalanche danger will persist.

Danger level
Danger Level 2 - Moderate above the treeline
Danger Level 1 - Low above the treeline
Avalanche Problem
Wind-drifted snow above the treeline, N-NE-E-SE-S-SW-W-NW

Fresh wind slabs above the tree line.

As a consequence of the snowfall, the likelihood of dry avalanches being released will increase a little especially above the tree line. Especially in places where the wind is storm force the avalanche danger is greater. The number and size of avalanche prone locations will increase as the day progresses. The avalanche prone locations are to be found in particular adjacent to ridgelines and in gullies and bowls in all aspects. They will increase with altitude. In the regions neighbouring those that are subject to danger level 3 (considerable) the avalanche danger is higher.

Snowpack

dp 6: cold, loose snow and wind

5 to 15 cm of snow. will fall. The northwesterly wind will transport the snow. As a consequence of fresh snow and a storm force wind from northwesterly directions, brittle wind slabs will form in particular on east, south and southwest facing slopes.

Tendency

The avalanche danger will persist.
