Glide-snow/wet-snow avalanches in steep terrain plus minor persistent weak layer at high-alpine altitudes

Avalanche danger is generally low. On steep slopes in extended southern aspects, isolated naturally triggered glide-snow/wet-snow avalanches can be expected to trigger in places. Above 2000 m, isolated slab avalanches can be triggered by large additional loading in transitions into steep gullies, reaching medium size (persistent weak layer). In the southern ranges isolated fresh instable snowpack patches on north-facing slopes require special caution, they can unleash small slab avalanches. Danger of falling outweighs that of being buried in snow.

Older snowdrifts have been able to settle further due to higher temperatures, only on shady high-altitude shady slopes are the weak layers still prone to triggering. Small drifts have accumulated in the southern ranges, these can be instable for a brief period. Otherwise the snowpack surface above 2000 m is often hard and icy, at intermediate altitudes it is mostly moist-to-wet and glides over smooth ground. The slopes at intermediate and lower altitudes are becoming bare of snow.

The SW airstream will continue on Saturday, minor snowfall is expected at high altitudes in the southern ranges, snowfall level at 1600 m. Winds in the rimline ranges and eastern ranges will be strong, in the western ranges brisk, from S/SW directions. At 2000 m: 0 to +2 degrees.

On Sunday skies will be predominantly overcast, peaks will be shrouded in fog. From the south, light to moderate precipitation will set in and spread throughout the mountains, snowfall level descending during the day from 1900 down to 1300 m. Slight snowdrift problem at high altitudes.
