Danger level

treeline
Avalanche Problem
Wind-drifted snow
Treeline


Wind slabs require caution.

The fresh and somewhat older wind slabs are prone to triggering in all aspects above the tree line. Mostly avalanches are rather small but can be released even by a single winter sport participant. The prevalence of avalanche prone locations and likelihood of triggering will increase with altitude.
On steep sunny slopes only isolated gliding avalanches are possible.

Snowpack

dp.6: cold, loose snow and wind

Little snow will fall. As a consequence of new snow and a strong wind from variable directions, mostly small wind slabs will form above the tree line. In some places wind slabs are lying on the soft surface of an old snowpack. In its middle, the snowpack is well consolidated. Towards its base, the snowpack is faceted, especially on shady slopes above the tree line, as well as in all aspects in high Alpine regions.
At low and intermediate altitudes no snow is lying.

Tendency

Slight increase in danger of dry avalanches as a consequence of the strong northerly wind.

The fresh and somewhat older wind slabs are prone to triggering in all aspects above the tree line. Mostly avalanches are rather small but can be released even by a single winter sport participant. The prevalence of avalanche prone locations and likelihood of triggering will increase with altitude. In regions neighbouring those that are subject to danger level 3 (considerable) the avalanche prone locations are more prevalent and the danger is greater.
On steep sunny slopes only isolated gliding avalanches are possible.

Snowpack

dp.6: cold, loose snow and wind

Over a wide area 5 cm of snow, and even more in some localities, will fall. As a consequence of new snow and a strong wind from variable directions, mostly small wind slabs will form above the tree line. In some places wind slabs are lying on surface hoar, especially on shady slopes. In its middle, the snowpack is well consolidated. Towards its base, the snowpack is faceted, especially on shady slopes above the tree line, as well as in all aspects in high Alpine regions.

Slight increase in danger of dry avalanches as a consequence of the strong northerly wind.
