Heed: snowdrift accumulations at high altitudes

Heed: snowdrift accumulations at high altitudes

Avalanche danger at high altitude is moderate. Isolated releases are most possible in extremely steep terrain. In addition, snowdrifts require increasing attentiveness with ascending altitude, esp. in ridgeline terrain. Small slab avalanches can often be triggered. Due to daytime warming and rain impact, wet slides and avalanches are possible, on steep grassy slopes also glide-snow avalanches.

As a result of fresh snow and winds, fresh snowdrift accumulations were generated with increasing altitude over the last few days which can now stabilize due to warmth and solar radiation. The moist old snowpack surface is well consolidated. Due to the lack of nocturnal outgoing radiation it cannot freeze over and thus, softens quickly in the daytime. Isolated weak layers are possible trigger-sensitive on steep shady slopes. At low and intermediate altitudes the ground is often bare of snow, esp. on sunny slopes. Avalanche Warning Services no longer have as much information from these regions.

Nocturnal hours: gray skies, some rainfall, snowfall above 1500 m. Thursday: mostly dry, clouds will disperse, convective cloud build-up is anticipated. Some sunshine. Clouds will move in during the evening. At 2000 m: -2 to +3 degrees. Moderate to brisk westerly winds.

Friday will be gloomy and rainy, snowfall above 2400 m. Fresh drifts will form in high alpine regions. With rainfall and warmth, more wet-snow avalanches can be expected.
