Isolated glide snow avalanches can grow to large size.

Isolated glide snow avalanches can grow to large size.

Avalanche danger is moderate. Main problem: snowdrifts. On north-facing slopes, medium-sized slab avalanches can be triggered even by minimal additional loading. Avalanche prone locations mainly occur below steepening slopes and in wind-loaded gullies and bowls. The higher the altitude the bigger they become. Experienced individuals will recognize and avoid them. In addition, the gliding snow danger persists. Avalanche prone locations occur on very steep slopes with smooth ground in all aspects. Isolated glide snow avalanches can grow to large size. Smaller wet loose snow avalanches can also trigger naturally in steep rocky terrain, in particular due to solar radiation.

In open terrain, Foehn transports the still loose superficial snow on shady slopes and generates snowdrift accumulations in leeward zones which are deposited atop loose dry snow and partly atop surface hoar. On the sunny side, a nocturnal melt-freeze crust forms that is not capable of bearing loadings. The recent snow moistens more and more due to mild temperatures and sunshine. The old snowpack as such is stable, completely moist and wet down to the ground. There is barely any snow below 1500 m.

Slab avalanche danger will recede slowly.
