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.

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 in shady steep terrain. Beware snowdrifts.

Near-surface weak layers are often still prone to triggering, esp. on little-tracked steep shady slopes. On shady steep high-altitude slopes and in ridgeline terrain, small-area snowdrift accumulations require caution. One sole winter sports enthusiast can trigger mostly small slab avalanches in these zones. 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. On steep grass-covered slopes with sufficient snow, isolated medium-sized glide-snow avalanches still possible.

Snowpack

Fresh snowfall is expected (5cm) which will be deposited up to high altitudes atop a weak old snowpack surface, it will bond well. In high-altitude ridgeilne terrain, small drifts will be generated. Below 1500m there is little snow on the ground. On shady slopes at high and high-alpine altitudes the older drifts lie atop an unfavorable old snowpack, which are often still prone to triggering.

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.

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. At high altitudes the old snowpack fundament is poor on shady slopes but the requisite slab is lacking.

Wer snow problem. Danger spots in some places within the old snow in high altitudes

The avalanche danger is low. Spontaneous moist loose-snow avalanches can trigger during the course of the day. Danger spots are found especially in full steep gullies, bowls and slopes. Weak layers within the old snow can be triggered with high additional loads in very few places and lead to small sized slab avalanches. Danger spots are located in very steep shady slopes above 2.000 m. The amount of danger spots increases with altitude.

Snowpack

Despite the cooler temperatures the settling of the snow surface is insufficient. Additional soaking due to rainshowers and sun radiation and snow melting lead to destabilization of the snow cover below 2.000 m. In steep shady slopes above 2.000 m weak layers of faceted snow are found within the snow base. Partially the snow surface is hard due to strong winds.

Tendency

Thursday night will be clear due to a intermediate high pressure system. During the day dry, mild and sunny weather is called. In the afternoon clouds are coming. Increasing avalanche danger due to wet snow problem.

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.

The setteling process of the snowcover is insufficient. Additional soaking due to sun radiation lead to destabilization of the snow cover. In places the snowsurface is hard duvets strong winds.

Danger level

Wet snow

Avalanche danger is low. Wet snow can be problematic. Isolated small loose snow avalanches can trigger naturally in extremely steep terrain. Isolated small glide-snow avalanches can still occur on steep, smooth slopes.

Snowpack

The snowpack is completely soaked, can only consolidate slightly during a mild, cloudy night. The snowpack is wet down to ground layers and can start gliding over smooth ground. You will now mostly only still find a cohesive snow cover on shady side slopes above approx. 1500m. Frequently, south-facing terrain is almost completely bare.

Tendency

No significant change of avalanche danger anticipated.
