Danger level

treeline

Persistent weak layer

Treeline

Weak layers in the old snowpack can be released by individual winter sport participants in all aspects. Whumpfing sounds and shooting cracks when stepping on the snowpack can indicate the danger. The avalanche prone locations are covered with new snow and are therefore difficult to recognise.

As a consequence of new snow and wind, sometimes easily released wind slabs formed in the last few days in particular in gullies and bowls and behind abrupt changes in the terrain as well as above the tree line. Weak layers exist in the snowpack in particular on steep shady slopes. On steep slopes slab avalanches are possible.

Snowpack

dp.1: deep persistent weak layer

Little snow has fallen in some regions. The various wind slabs have bonded poorly with the old snowpack. In particular above the tree line snow depths vary greatly, depending on the infuence of the wind. The meteorological conditions will foster a gradual strengthening of the snowpack. Gradual decrease in avalanche danger as a consequence of warming during the day and solar radiation.

Tendency

The avalanche danger will decrease.

Treeline

Individual avalanche prone locations are to be found in particular on steep slopes at high altitude, also on steep shady slopes in areas close to the tree line. The various wind slabs have bonded poorly with the old snowpack. The avalanche prone locations are clearly recognisable to the trained eye.

Snowpack

The various wind slabs have bonded poorly with the old snowpack. In particular above the tree line snow depths vary greatly, depending on the infuence of the wind. Below the tree line hardly any snow is lying. The meteorological conditions will foster a gradual strengthening of the snowpack. Gradual decrease in avalanche danger as a consequence of warming during the day and solar radiation.

Tendency

The avalanche danger will decrease.
