Freshly generated snowdrifts atop unfavorable old snowpack
Freshly generated snowdrift accumulations can still be triggered, particularly in ridgeline terrain, gullies and bowls in all aspects. Due to increasing winds and fresh snowfall, frequency of danger zones will increase during the daytime hours and with ascending altitude. Marked weak layers in the old snowpack can be triggered by one single winter sports enthusiast, particularly on steep, little skied on slopes. The danger zones are not visible. Triggered avalanches can grow to medium size. Whumpf noises and fractures when treading on the surface are alarm signals. Activities in backcountry demand careful evaluation of the terrrain and assessment of the dangers. In zones where there is rain impact, wet snowslides and avalanches are possible.
Snowpack
Fresh snow and drifts lie deposited on top of an often melt-freeze encrusted snowpack surface, otherwise atop surface hoar. Especially on steep shady slopes, the frequently unfavorable base is poorly-to-moderately consolidated. In zones with rain impact, the snowpack will be temporarily weakened.
Tendency
As a result of further fresh snowfall and wind, avalanche danger will increase somewhat. Triggerings in the old snow are still possible.

Beware fresh snowdrift accumulations
Freshly generated snowdrift accumulations are prone to triggering, occur particularly in ridgeline terrain, gullies and bowls in all aspects. Due to increasing winds and snowfall, frequency of danger zones increases with ascending altitude and during the course of the day. A single winter sports enthusiast can trigger medium-sized slab avalanches in some places, particularly on high-altitude steep shady slopes and in extremely steep terrain, which then trigger down to deeper layers inside the snowpack. In zones where there is rain impact, wet snowslides and avalanches are possible.
Snowpack
A small amount of fresh snow and drifts lie deposited on top of an often melt-freeze encrusted snowpack surface, otherwise atop surface hoar. Especially on steep shady slopes, the often unfavorable base and intermediate layers of the old snowpack have persisted. In zones with rain impact, the snowpack will be temporarily weakened.
Tendency
As a result of more fresh snowfall and wind, avalanche danger will increase somewhat.
