Still trigger-sensitive intermediate layers on high-altitude shady slopes

Still trigger-sensitive intermediate layers on high-altitude shady slopes

Main problem: weak layers in upper part of the snowpack. Near ridgelines they can be triggered as a slab avalanche by winter sports enthusiasts on steep shady slopes, but releases tend to remain small. Due to solar radiation and daytime warming, small loose-snow avalanches are possible on sunny slopes.

Temperatures have risen noticeably at high altitude, the proneness to triggering has diminished. In the upper part of the snowpack are expansively metamorphosed (faceted) crystals. On very steep sunny slopes there is a thin melt-freeze crust on the surface. Elsewhere the snowpack is often powdery. At intermediate altitudes there is surface hoar. Due to solar radiation and daytime warming the snowpack softens on sunny slopes.

Nocturnal hours: star-studded skies, cold. Sunday: sunny but cold winds, though not as brisk as yesterday. At 2000 m: -4 to +2 degrees. Light to moderate NE winds.

Zero-degree level rising to nearly 3000 m on Monday. Danger of dry-snow avalanches will diminish further. Due to solar radiation and daytime warming, risks of wet-snow and glide-snow avalanches will increase during the course of the day.
