A sometimes treacherous avalanche situation will prevail. Weakly bonded old snow is to be evaluated with care and prudence.
Avalanches can be released in the weakly bonded old snow by a single winter sport participant. This applies in particular on west, north and east facing slopes above approximately 1800 m. Mostly avalanches are medium-sized. Remotely triggered avalanches are possible in isolated cases.
The avalanche prone locations are quite prevalent and are barely recognisable. Individual avalanche prone locations are to be found also in areas close to the tree line. The number and size of avalanche prone locations will increase with altitude. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack can indicate the danger.
Snowpack
dp.1: deep persistent weak layer dp.6: cold, loose snow and wind
The fresh snow of last week and the sometimes large wind slabs are lying on top of a weakly bonded old snowpack. The old snowpack is faceted.
Distinct weak layers exist in the snowpack.

Avalanches can as before be released by a single winter sport participant.

A treacherous avalanche situation will prevail. Weakly bonded old snow is to be evaluated critically.
Avalanches can be released in the weakly bonded old snow, even by a single winter sport participant. This applies in particular on west, north and east facing slopes above approximately 1800 m, in isolated cases also on south facing slopes above approximately 2200 m. Mostly avalanches are medium-sized. Remotely triggered avalanches are possible.
The avalanche prone locations are widespread and are barely recognisable. Individual avalanche prone locations are to be found also in areas close to the tree line. The number and size of avalanche prone locations will increase with altitude. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack serve as an alarm indicating the danger.

Weak layers in the old snowpack necessitate caution. Fresh wind slabs require caution.
Avalanches can be released in the weakly bonded old snow by a single winter sport participant. This applies in particular on west, north and east facing slopes above approximately 2200 m. Caution is to be exercised in particular in gullies and bowls, as well as at transitions from a shallow to a deep snowpack. Mostly avalanches are medium-sized.
The fresh wind slabs can be released at elevated altitudes. This applies in particular adjacent to ridgelines. Mostly avalanches are small.
The number and size of avalanche prone locations will increase with altitude. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack can indicate the danger.
Snowpack
dp.1: deep persistent weak layer dp.6: cold, loose snow and wind
As a consequence of a gusty wind from northerly directions, mostly small wind slabs formed. As a consequence of a strengthening wind from southerly directions, further wind slabs will form. The fresh wind slabs will be deposited on surface hoar in some places.
The old snowpack is faceted and weak. Weak layers exist in the snowpack.
Tendency
Weak layers in the old snowpack can still be released by individual winter sport participants. As a consequence of a strong wind from southerly directions, easily released wind slabs will form.

Weakly bonded old snow represents the main danger.
Avalanches can be released in the weakly bonded old snow by a single winter sport participant. This applies in particular on west, north and east facing slopes above approximately 1800 m. Caution is to be exercised in particular in gullies and bowls, as well as at transitions from a shallow to a deep snowpack. In isolated cases avalanches are medium-sized.
The avalanche prone locations are difficult to recognise. Individual avalanche prone locations are to be found also in areas close to the tree line. Whumpfing sounds and the formation of shooting cracks when stepping on the snowpack can indicate the danger.
Snowpack
dp.1: deep persistent weak layer dp.6: cold, loose snow and wind
The new snow and wind slabs are lying on top of a weakly bonded old snowpack. The old snowpack is faceted.
Weak layers exist in the snowpack.
Tendency
Weak layers in the old snowpack can still be released by individual winter sport participants. As a consequence of a strong wind from southerly directions, easily released wind slabs will form. In some regions increase in avalanche danger.
