Weakly bonded old snow and gliding snow require caution.
Dry avalanches can in isolated cases be released by a single winter sport participant and reach medium size. This applies in particular on very steep shady slopes above approximately 2400 m.
More gliding avalanches are possible, even medium-sized ones. Caution is to be exercised in particular on steep grassy slopes below approximately 2400 m.
As a consequence of warming during the day and solar radiation only isolated mostly small wet loose snow avalanches are possible, in particular on extremely steep sunny slopes below approximately 2400 m.
Snowpack
dp.1: deep persistent weak layer dp.2: gliding snow
Outgoing longwave radiation during the night will be good over a wide area. The surface of the snowpack will soften during the day, in particular on sunny slopes below approximately 2400 m, as well as in all aspects at low and intermediate altitudes. Below approximately 2000 m: The snowpack is wet all the way through.
Isolated avalanche prone weak layers exist in the bottom section of the old snowpack. This applies especially on shady slopes above approximately 2400 m.

Wind slabs represent the main danger.
The wind slabs must be evaluated with care and prudence especially on very steep west, north and east facing slopes. The avalanche prone locations are to be found in particular in gullies and bowls, and behind abrupt changes in the terrain above approximately 2400 m. Avalanches can in isolated cases reach medium size. Apart from the danger of being buried, restraint should be exercised as well in view of the danger of avalanches sweeping people along and giving rise to falls. Avalanches can additionally in very isolated cases be released in near-ground layers on very steep shady slopes.
Snowpack
dp.1: deep persistent weak layer dp.6: cold, loose snow and wind
Less snow than usual is lying in all altitude zones. The snowpack will be subject to considerable local variations. The wind slabs are lying on top of a weakly bonded old snowpack on west, north and east facing slopes at elevated altitudes. Faceted weak layers exist in the bottom section of the old snowpack in shady places that are protected from the wind. Steep sunny slopes: The solar radiation will give rise as the day progresses to increasing moistening of the snowpack.
Tendency
The weather will be mild. A little snow is lying.

Weakly bonded old snow requires caution.
In isolated cases avalanches can be triggered in the weakly bonded old snow. Such avalanche prone locations are to be found in particular on very steep northwest, north and northeast facing slopes above approximately 2400 m. Mostly avalanches are small. Apart from the danger of being buried, restraint should be exercised as well in view of the danger of avalanches sweeping people along and giving rise to falls.
As a consequence of warming during the day and solar radiation only isolated mostly small wet loose snow avalanches are possible, in particular on extremely steep sunny slopes below approximately 2400 m.
In addition further small to medium-sized gliding avalanches are possible. Caution is to be exercised in particular on very steep grassy slopes.
Snowpack
dp.1: deep persistent weak layer
Shady places that are protected from the wind above approximately 2400 m: Avalanche prone weak layers exist deeper in the old snowpack.
Very steep sunny slopes below approximately 2400 m: The weather conditions gave rise to significant moistening of the snowpack. Outgoing longwave radiation during the night will be good over a wide area. Sunshine and high temperatures will give rise as the day progresses to softening of the snowpack.
The snowpack will be subject to considerable local variations. From a snow sport perspective, in most cases insufficient snow is lying.
Tendency
Decrease in avalanche danger. The weather will be mild.

Gliding snow requires caution.
More gliding avalanches are possible, even medium-sized ones. Caution is to be exercised in particular on steep grassy slopes below approximately 2400 m.
Dry avalanches can still in isolated cases be released by a single winter sport participant, but they will be small in most cases. This applies in particular on very steep shady slopes above approximately 2400 m.
As a consequence of warming during the day and solar radiation only isolated mostly small wet loose snow avalanches are possible, in particular on extremely steep sunny slopes.
Snowpack
dp.2: gliding snow dp.8: surface hoar blanketed with snow
Outgoing longwave radiation during the night will be good over a wide area. The surface of the snowpack will soften during the day, in particular on sunny slopes below approximately 2400 m, as well as in all aspects at low and intermediate altitudes. Below approximately 2000 m: The snowpack is wet all the way through.
The somewhat older wind slabs are lying on surface hoar in some places on shady slopes above approximately 2400 m. This applies especially in the west.
Tendency
Gliding snow requires caution.
Danger level
Dry and wet avalanches can be released by people, but they will be small in most cases.
As a consequence of warming, the likelihood of moist snow slides during the day being released will increase a little, in particular on extremely steep sunny slopes, and at the base of rock walls. Avalanches can additionally in very isolated cases be released on extremely steep shady slopes. This applies in particular in gullies and bowls at elevated altitudes. Avalanches are small.
Apart from the danger of being buried, restraint should be exercised in particular in view of the danger of avalanches sweeping people along and giving rise to falls.
Snowpack
In all altitude zones hardly any snow is lying. Steep sunny slopes: The high temperatures will give rise to rapid moistening of the snowpack.
Steep shady slopes: In isolated cases various wind slab layers are lying on a weakly bonded old snowpack.
The snowpack will be subject to considerable local variations. From a snow sport perspective, in most cases insufficient snow is lying.
Tendency
The weather will be mild. A little snow is lying.

Gliding snow
Gliding snow requires caution. Thus far only a little snow is lying.
As a consequence of warming during the day and solar radiation only isolated mostly small wet loose snow avalanches are possible, in particular on extremely steep sunny slopes.
In addition further mostly small gliding avalanches are possible. Caution is to be exercised in particular on steep grassy slopes. Restraint should be exercised because avalanches can sweep people along and give rise to falls.
