Circumvent zones below glide cracks

Circumvent zones below glide cracks

Avlanche danger is low, gliding snow is the main problem. On steep grass-covered slopes and over rock plates where the snow depths are sufficient, small glide-snow avalanches can trigger naturally at any time of day or night.

The snow on sunny slopes and at low altitudes can form a melt-freeze crust at night which then softens during the daytime. Exposed ridges and crests are windblown, gullies, bowls and slopes near forest rims are filled with snow. The fresh fallen snow has settled in the interim. On shady slopes the fresh fallen snow is still loose, the snowpack was able to metamorphose repeatedly, forming faceted crystals. The entire snowpack can start to glide over steep rock plates or grassy slopes.

Following a night of clear skies, sunshine is expected above local fogbanks right from the start. Visibility will be outstanding. Winds will be weak to moderate from westerly directions. At 2000m: +4 degrees; at 3000m: -3 degrees.
