Danger level

2400m
Avalanche Problem
Persistent weak layer
2400m


Weakly bonded old snow is to be evaluated with care and prudence.

In some places avalanches can be triggered in the weakly bonded old snow and reach medium size in isolated cases. The avalanche prone locations are to be found in particular on steep west to north to east facing slopes above approximately 2400 m and on steep sunny slopes above approximately 2600 m. Caution is to be exercised at transitions from a shallow to a deep snowpack. The prevalence of the avalanche prone locations will increase with altitude.
The fresh wind slabs are mostly small but can be released in isolated cases. Caution is to be exercised in particular on steep shady slopes at elevated altitudes.
There is a danger of falling on the hard snow surface.

Snowpack

dp.1: deep persistent weak layer

Towards its base, the snowpack is faceted, especially on steep west, north and east facing slopes above approximately 2400 m, as well as on steep sunny slopes at elevated altitudes.
The northwesterly wind will transport the loosely bonded old snow. The fresh wind slabs are lying on soft layers in particular on shady slopes.
Towards its surface, the snowpack is hard and its surface has a melt-freeze crust. This applies in particular on steep sunny slopes.

Tendency

On Friday it will be very mild. The wind will be moderate to strong. The old snowpack remains prone to triggering in some places.

Weakly bonded old snow is to be evaluated with care and prudence. Fresh wind slabs require caution.

In some places avalanches can be triggered in the weakly bonded old snow and reach medium size in isolated cases. The avalanche prone locations are to be found in particular on steep west to north to east facing slopes above approximately 2400 m and on steep sunny slopes above approximately 2600 m. Caution is to be exercised at transitions from a shallow to a deep snowpack. The prevalence of the avalanche prone locations will increase with altitude.
Fresh wind slabs are mostly rather small but in some cases prone to triggering. Caution is to be exercised in particular on steep shady slopes at elevated altitudes, and in the regions exposed to heavier precipitation.

Snowpack

dp.1: deep persistent weak layer
dp.6: cold, loose snow and wind

Towards its base, the snowpack is faceted, especially on steep west, north and east facing slopes above approximately 2400 m, as well as on steep sunny slopes at elevated altitudes.
In some regions up to 10 cm of snow, and even more in some localities, will fall above approximately 1800 m. The westerly wind will transport the new snow and, in some cases, old snow as well. The various wind slabs are lying on soft layers in particular on shady slopes.

Tendency

On Friday it will be very mild. The wind will be moderate to strong. The old snowpack remains prone to triggering in some places.


Danger level



Low avalanche danger will prevail.

In very isolated cases avalanches can be triggered in the weakly bonded old snow. The avalanche prone locations are to be found in particular on steep west to north to east facing slopes. Fresh wind slabs are mostly rather small and can be released in isolated cases. Caution is to be exercised in particular on steep shady slopes at elevated altitudes.
As a consequence of warming during the day and solar radiation individual moist snow slides are possible. Mostly the avalanches are small.

Snowpack

Over a wide area a little snow is lying. Below approximately 1800 m from a snow sport perspective, in most cases insufficient snow is lying.
Towards its base, the snowpack is faceted, especially on steep west, north and east facing slopes.
Towards its surface, the snowpack is hard and its surface has a melt-freeze crust that is not capable of bearing a load. Low avalanche danger will prevail.

Tendency

On Friday it will be very mild. The wind will be moderate to strong. The avalanche danger will persist.
