Danger level


Avalanche Problem
Wet snow


Heed risk of taking a fall in steep terrain.

Avalanche danger is low. Small wet loose snow avalanches can release spontaneously on very steep sun-exposed slopes. Isolated glide snow avalanches can release on steep smooth grass-covered slopes.

Snowpack

The snowpack is thoroughly moist. A thin melt-freeze crust can form during the night which the sun will soften again during the day. The snowpack is wet where it touches the ground, i.e. it can start gliding over smooth ground. Snow depths vary. Ridges and crests are blown bare; south-facing slopes are becoming increasingly bare. All in all, there is little snow.

Avalanche Problem
Persistent weak layer
2200m
Wet snow


In places, weak layers in the old snowpack can be prone to triggering. Small wet snow avalanches possible at all altitudes.

Avalanche danger above 2200 m is moderate, below that altitude danger is low. Main problem: old snowpack. In some places, slab avalanches can be triggered by minimum additional loading. Avalanche prone locations are mainly found above 2200 m in steep east-facing terrain as well as in wind-loaded gullies and bowls. Avalanches generally remain small-sized. In addition, small wet loose snow avalanches can release naturally in very steep terrain. Isolated glide snow avalanches that are mostly small are possible on steep smooth grass-covered slopes.

Snowpack

As a consequence of warm temperatures, the different layers within the snowdrifts start bonding. In particular above 2200 m, trigger-sensitive layers persist in some places, and there are faceted crystals close to crusts. Up to high altitude the snowpack is thoroughly moist, widespread it is wet at ground level. During Tuesday night a thin melt-freeze crust can form that will soften again during the day. Snow depths vary; all in all there is little snow.

Tendency

Hardly any changes by Thursday. After Thursday, avalanche danger will rise due to forecast snowfall and wind.
