Snowdrifts still trigger-prone. Daily danger cycle.
The most recent fresh snow has bonded well, became moistened on Thursday up to high altitudes in all aspects. A melt-freeze crust forms at night then softens rapidly in morning. Beneath the fresh snow the snowpack is thoroughly moist down to the ground below 2500 m. Danger zones for dry-snow avalanches occur esp. on steep shady slopes at high and high-alpine altitudes.
Nocturnal hours: Clear skies or scattered clouds, good outgoing radiation. Friday daytime: Sunny and very mild, thin high-altitude clouds. At 2000 m: at midday -+10 degrees. Light W/NW winds.
Due to sunny and mild conditions, danger of dry-snow avalanches will recede further. Following nights of cleaer skies, favourable conditions reign in the mornings. Due to solar radiation and warmth, danger of wet-snow avalanches rises significantly during the course of the day.
Snowdrifts still trigger-prone. Daily danger cycle.
Above 2200 m avalanche danger is moderate. With ascending altitude and in high-alpine regions, fresh snowdrift accumulations and fresh snow are prone to triggering, esp. in ridgeline terrain and in wind-loaded gullies and bowls. Easily triggerable! Danger of wet-anow avalnches has receded as temperatures dropped, but will increase again, and more loose-snow avalanches can be expected to release from the fresh fallen snow. Glide-snow avalanches are still possible, esp. in starting zones where there is sufficient snow, releases can be large. Caution below glide cracks. Huge cornices still require caution.
