Latent persistent weak layer problem

Latent persistent weak layer problem

The avalanche risk is low. The main problem is a persistent weak layer. Avalanche prone locations are mainly in the northern aspects of the high altitudes on very steep slopes as well as in gullies and bowls. Slab avalanches can be triggered with a large additional load and can reach medium size. Be careful at transitions from little to much snow.

In addition, smaller loose snow avalanches can release themselves from steep terrain interspersed with rocks. At medium altitudes, individual small to medium-sized gliding avalanches are possible on slopes with a smooth surface.

On the shady slopes, weak layers of faceted crystals can be found deep under a compact, crusted can form at high altitudes. At night, it is mostly cloudy and outgoing longwave radiation is limited. There may be some localised snowfall at higher altitudes. The snow comes to rest on a thin, superficial melt-freeze crust on the north side, under which faceted crystals have formed. At medium elevations, the snow surface is already soft in many places in the morning. The snowpack is wet towards the ground. On the south side, the ground is still pitting. There is hardly any snow at low altitudes.

Depending on the amount of new snow, the danger of dry avalanches may increase slightly.
