Slightly rising avalanche danger - small-area freshly generated snowdrifts
Avalanche danger above the timberline is moderate, below that altitude danger is low. Small to medium-sized slab avalanches can be triggered by one sole skier. Danger zones occur esp. on shady, ridgeline steep slopes and in wind-loaded gulliex and bowls. Size and frequency tend to increase in frequency with ascending altitude and during the course of the day. Danger of mostly small-sized glide-snow avalanches on grass-covered slopes or rocky plates still prevails. Therefore, caution urged below glide cracks.
By tomorrow evening in the northern regions, 10-20cm of fresh snow is expected. Winds will be moderate to brisk from westerly to northwesterly directions, generating fresh, often trigger-sensitive snowdrift accumulations. Bonding to the old snowpack surface deteriorates with ascending altitude. The below-average snowpack depths are generally well consolidated. Snowpack surfaces are highly varied: high altitude shady slopes are often still powdery, elsewhere there are breakable crusts, sometimes wind crusts are capable of bearing loads. On sunny slopes, a melt-freeze crust forms. Due to dropping temperatures, gliding snow activity will gradually recede.
Low-pressure front conditions. Clouds and fog will remain dense, light snowfall is possible. In afternoon hours, extended dry phases, in evening the clouds will gradually disperse. Temperatures dropping to wintery levels. At 2000m: -6 degrees. Winds moderate to brisk from W/NW.
Assess with caution the zones with fresh snowdrifts
