On extremely steep slopes, generally small-sized wet loose-snow avalanches are possible. In addition, isolated small-to-medium wet slab avalanches are possible at the foot of rock walls, esp. during the afternoon hours, in starting zones which have not yet discharged. Weak layers in the old snowpack can in isolated cases be triggered by one sole skier. Such danger zones occur on very steep shady slopes and in transitions into gullies and bowls above 1900m, and can reach medium size.

Daytime increase in avalanche danger due to fresh snow and wind
Avalanche danger during the morning will be moderate above 2200m, below that altitude danger is low. With increasing amounts of fresh fallen snow, avalanche danger above 2200m will rise to CONSIDERABLE. Avalanches can in some zones be triggered by one sole skier, esp. in the afternoon, and grow to medium size. Danger zones occur in the old snow on north-facing slopes above 2200m, in all aspects above 2400m. Fresh snowdrift accumulations occur both near to and distant from ridgelines, behind protruberances in the terrain, and in gullies and bowls. Particularly below 2000m the old snowpack is thoroughly wet and small-to-medium wet-snow avalanches are possible. Avalanches in high altitudes can sweep along more deeply embedded layers of the snowpack and in isolated cases plummet all the way down to the green zones. Small-to-medium glide-snow avalanches can trigger naturally in very to extremely steep grass-covered terrain.
Snowpack
By Saturday evening 30cm of fresh snow is anticipated at high altitudes. Above 2200m on north-facing slopes weak layers of faceted crystals are found in the lowermost part of the snowpack. Above 2400m on W/S/E facing slopes there are faceted crystals between crusts. Inside the snowdrifts, in addition, trigger-sensitive layers can form rapidly. Below 2000m the snowpack will forfeit its firmness on Friday night due to rainfall and water seepage.

Increasing danger of wet-snow avalanches during the course of the day. Caution: weak layers in the old snow
On extremely steep slopes, mostly small wet loose-snow avalanches are possible. In addition, during afternoon isolated small-to-medium wet slab avalanches are possible esp. as of midday. Caution on sunny slopes below 2600m and on shady slopes below 2200m. Weak layer can still be triggered in places by one sole skier. Such danger zones occur esp. on N/W/E facing slopes above 2000m. Extremely isolated danger zones occur on sunny slopes above 2600m, avalanches can grow to medium size. In addition, small snowdrift accumulations require caution, they can be triggered by one sole skier in some places by large additional loading esp. on shady slopes.

Daytime rise in avalanche danger due to fresh snow and wind
The fresh snow will be transported by northerly winds, generating mostly small-sized trigger-sensitive snowdrift accumulations at high altitudes, esp. on shady slopes. Isolated winter sports enthusiasts in these zones can trigger small slab avalanches. Apart from the danger of being buried in snow masses, the risks of being swept along and forced to take a fall require adequate caution. The danger of small, in isolated cases medium-sized glide-snow avalanches persists. At intermediate altitudes the old snowpack is thoroughly wet and mostly small wet-snow avalanches are possible.
Snowpack
In Bregenzerwald and the Pre-Alps up to 15cm of fresh snow is expected, the snowfall level will drop rapidly from 1700 down to 1300m. The fresh fallen snow will be transported during the course of the day by intensifying northerly winds. At high altitudes the fresh snow and drifts will be deposited atop soft layers particularly on shady slopes and is prone to triggering. The snowpack is moist up to high altitudes and weakened by rainfall. Gliding movements are still possible over smooth ground.
Tendency
Also on Sunday, brisk NW winds will generate new snowdrifts. Danger of dry-snow avalanches will not change significantly. During the daytime, wet-snow and glide-snow avalanches continue to be possible.

Daytime increase in avalanche danger. In high-alpine regions: beware hidden weak layers.
Daytime warming and solar radiation lead to increasing avalanche danger during the course of the day. In early morning, danger above 2300m is moderate, below that altitude danger is low. During the daytime it rises at all altitudes to moderate. Below 2400m, increasingly frequent small-to-medium wet-snow avalanches are possible in as aspects on steep slopes. In zones which have not yet discharged, also higher up. Small-to-medium glide-snow avalanches can trigger naturally on very steep grass-covered slopes. Above 2300m in some places, dry slab avalanches can be triggered even by one sole skier. Danger zones occur in very steep terrain and on liitle-tracked NW/NE facing slopes. Releases can fracture in the old snowpack and down to more deeply embedded layers, thereby reaching medium size.
Avalanche danger is moderate. Wet-snow avalanches can be triggered by one sole skier on steep slopes in all aspects in steep sunny terrain which has not yet discharged. Small-to-medium glide-snow avalanches can trigger naturally on extremely steep grass-covered slopes. Above 2300m, dry slab avalanches can still be triggered by one sole skier. Danger zones occur on very steep, little-tracked slopes on NW/NE facing slopes. Avalanches can fracture down to more deeply embedded layers in the snowpack and reach medium size. Small freshly generated snowdrift patches are often prone to triggering, esp. on very steep shady slopes in high-alpine ridgeline terrain. Apart from the danger of being buried in snow masses, the risks of being swept along and forced to take a fall demand adequate consideration.
Snowpack
The snowpack cools at night and forms a melt-freeze crust which is usually capable of bearing loads. During the daytime the snowpack then softens and forfeits its bonding. On shady slopes at high and high-alpine altitudes there are several weak layers of facted crystals inside the old fundament. Also moist slabs can slide away on sunny slopes over the surface crusts.
Tendency
Dense clouds at night, the snowpack can hardly cool. Snowfall will set in. Avalanche danger will increase during the course of the day.

Wet snow
The avalanche danger is low. Due to soaking small moist and wet avalanches can’t be ruled out. Danger spots are found especially in full steep gullies, bowls and slopes.
Snowpack
The snow cover can settle during the night. During the day the snow cover which is wet till the base, softens and loses its stability. In steep shady slopes weak layers of faceted snow are found within the snow base.
Tendency
Friday night the weather is changing. The snowline is 1.200 m in the north and 1.500 m in the south and 10-30 cm new snow is expected. The most will be in Nordstau areas. Visibility will be poor. Northerly winds which are increasing during the day. The avalanche danger increases with altitude.

Small loose snow avalanche can trigger, in particular due to solar radiation.
Avalanche danger is low. Wet snow can be problematic. During the course of the day, small loose-snow avalanches can trigger naturally in extremely steep terrain. Isolated mostly small sized glide-snow avalanches cannot be ruled out on steep, smooth slopes. Isolated small dry slab avalanches can release on very steep high altitude slopes close to ridgelines in W/N/E aspects.
Snowpack
During the course of a partly clear night a melt-freeze crust capable of bearing loads will form atop the moist snowpack which will soften again during the course of the day. In many places the snowpack is wet down to the ground. Possibility of gliding movements over smooth ground. At high altitudes there are a few centimeters of loose superficial snow. Here and there, small snowdrift patches have formed. In isolated cases, a weak layer can persist near the ground on shady side slopes at highest altitude. In south aspects, the snowpack has become patchy even at high altitude.
Tendency
Snowfall is forecast, thus the avalanche danger will increase on Saturday.

Wet loose-snow and glide-snow avalanches in very steep terrain are the main danger
Avalanche danger is low. Isolated small loose-snow naturally triggered avalanches are possible or can be triggered by one sole skier. Danger zones for small slab avalanches in the snowdrifts occur seldom on very steep north-facing slopes at high altitudes. On steep grass-covered slopes, isolated small glide-snow avalanches are possible. Apart from the danger of being buried in snow masses, the risks of being swept along and forced to take a fall demand adequate consideration.small wet loose-snow avalanches are possible in very-to-extremely steep terrain in all aspects. The gliding snow activity will increase, small-to-medium glide-snow avalanches are possible on steep grass-covered slopes. Above 2300m, only few danger zones where still small dry slab avalanches can be triggered. Apart from the danger of being buried in snow masses, the risks of being swept along and forced to take a fall demand adequate consideration.

The snowpack cools at night and forms a melt-freeze crust which is usually capable of bearing loads. During the daytime the snowpack then softens and forfeits its bonding. On shady slopes at high and high-alpine altitudes there are several weak layers of facted crystals inside the old fundament. At high altitudes the old snowpack fundament is poor on shady slopes but the requisite slab is lacking.
