Caution in transitions from shallow to deeper snow
Caution in transitions from shallow to deeper snow
In some places avalanches can be triggered by one sole skier, mostly above 2000m in transitions from shallow to deep snow, e.g. at entry points into gullies and bowls, the releases mostly small-to-medium. Danger zones tend to increase in frequency with ascending altitude, particularly on steep shady slopes, but also behind protruberances in the landscape. In addition, on very steep grassy slopes, small-to-medium glide-snow avalanches can trigger naturally.
The fresh snow from the beginning of the week lies deposited atop an unfavorable old snowpack surface, particularly on shady slopes. As a result of strong southerly winds it was transported far-reachingly. The snowdrifts are often poorly bonded with the old snowpack and are prone to triggering. Avalanche triggerings are possible esp. inside the near-surface layers and in transitions to the old snow. Snowdrifts have often been blanketed, making them hard to recognize. On sunny slopes the most recent fresh fallen snow is already bonded. The old snowpack beneath it is well consolidated. At lower altitudes the fresh snow often fell on bare ground.
Mostly sunny, slightly foehn-impacted winter sports weather with good visibility. Winds moderate. More cloud in Silvretta and Rätikon. At 2000m: -7 to -1 degree. Light to moderate S/SW winds.
Avalanche danger levels will decrease further
