Weak old snow and fresh snowdrifts prone to triggering
Fresh fallen snow and freshly generated snowdrifts are poorly bonded with the weak old snowpack. One single person can trigger slab avalanches in the drifts and old snow. If the fracture sweeps away the entire snowpack, the release can grow to medium size. Danger zones are located in all aspects, but especially on shady slopes and in wind-loaded gullies and bowls. Frequency and spread of avalanche prone locations increase with ascending altitude. Activities in backcountry demand defensive conduct.
Snowpack
Fresh snowfall is anticipated: 15-30cm, as much as 50cm in Verwall and Lechquellengebirge. It will be transported by intermittently strong to storm-strength westerly winds. The fresh snow and fresh snowdrifts since Thursday frequently lie deposited atop a loosely-packed, faceted and expansively metamorphosed old snowpack surface or on surface hoar. Bonding is poor. The old snowpack is unfavorably structured.
Tendency
As a result of more snowfall and wind, avalanche danger to rise significantly by Sunday

Rising avalanche danger above the timberline
Freshly generated snowdrift accumulations and weak layers in the old snow are prone to triggering. One single winter sports enthusiast can trigger small-sized slab avalanches. Danger zones occur especially near ridgelines and in wind-loaded gullies and bowls, as well as in extremely steep terrain. Apart from the risks of being buried in snow, the danger of being swept along and forced to take a fall require caution.
