Following a mild night with overcast skies and reduced outgoing radiation, moderate danger prevails. Naturally triggered wet-snow and glide-snow avalanches can be expected, reaching medium size in high-altitude starting zones. Wet-snow avalanches can be triggered by persons in steep terrain. In addition, the old snowpack can be triggered by large additional loading in extremely steep terrain. Apart from the danger of being buried in snow masses, the risks of being swept along and forced to take a fall require adequate caution.
Snowpack
On E/S/W-facing slopes up to high-alpine regions and on shady slopes up to 2200m, the moist snowpack is able to consolidate somewhat during the nighttime hours. Due to rainfall in the afternoon up to 2500m, the snowpack will be further weakened. On very steep shady slopes at high altitudes, unfavorable intermediate layers are evident inside the old snowpack.
Tendency
Wet-snow and gliding snow remain the major danger.

Danger of wet avalanches even in the morning.
Avalanche danger below 2800m is considerable, above that altitude danger is moderate. Danger zones for wet-snow and glide-snow avalanches occur on very steep shady slopes below 2400m, on very steep sunny slopes below 2800m. Following a mild night with overcast skies and reduced outgoing radiation, only a thin melt-freeze crust could form, which will soften up rapidly. Avalanches can trigger naturally in all aspects in high-altutude starting zones. If they sweep along the thoroughly wet old snowpack they can in isolated starting zones where snow is sufficient grow to large size. In addition, the old snowpack can be triggered by large additional loading in extremely steep terrain. Danger zones occur in seldom-skied backcountry touring terrain, esp. on very steep NW/N/NE-facing slopes and are difficult to recognize. Backcountry tours require a cautious route selection.
