Glide-snow avalanches + daily cycle of naturally triggered avalanche activity

Glide-snow avalanches + daily cycle of naturally triggered avalanche activity

Due to daytime warming and solar radiation, increasing wet-snow avalanches can be expected. Also glide-snow avalanches can be expected in starting zones where there is still sufficient snow on the ground, growing to medium size. Avoid zones below glide cracks.

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.
