Avoid zones below glide cracks

Avoid zones below glide cracks

Avalanche danger is moderate. Fresh fallen snow is the main problem: it can trigger naturally or by 1 person in all aspects as loose-snow avalanches. In steep ridgeline terrain the snow is bonded by wind impact and can be triggered by 1 peson. Danger zones are difficult to recognize. Loose-snow and slab avalanches can reach medium size. In addition, gliding snow can be problematic. On very steep grass-covered slopes in all aspects, glide-snow avalanches can releases naturally, esp. where the slopes were bare of snow before the precipitation, medium sized releases possible. Glide cracks are signals of imminent danger.

Northerly winds can transport the loose snow during the day, snowdrifts are generated atop soft trigger-prone layers, their proneness to triggering increases with ascending altitude. Due to diffuse light the near-surface snow loses its bonding and can release as a loose-snow avalanche. The snow is settling and bonding increasingly up to high altitudes. At the base, it is wet, reinforcing gliding movements over smooth ground.

On Thursday, cool. Avalanche danger levels are not expected to change significantly.
