Snow showers probably only in the early part of the day. On Sunday, cold NE winds, snowfall in the afternoon. Avalanche danger is not expected to change significantly.

Initial sunshine and, as a result of solar radiation, convective cloud build-up, this afternoon some snow/graupel showers will follow. On Friday night, light snowfall in Allgau Alps and Arlberg in particular. Temperature at 2000 m: -11 degrees. Light winds from varying directions for a short period. Snow cover / General info There was only an additional 5 cm of fresh snow registered on Thursday night. The recent snowfall is settling and consolidating slowly due to low temperatures. The springtime level of solar radiation pushes the snow to settle, despite the low temperatures. Intermittent moderate-to-strong winds have generated trigger-sensitive snowdrifts: exposed zones often windblown, gullies and bowls filled with drifts. On shady slopes, fresh snow and drifts often were deposited on soft old snowpack layers, on sunny slopes atop hard, encrusted layers. In addition, graupel was often blanketed over. Bonding to the old snowpack and inside the drifts is weak-to-moderate. The old snowpack is well consolidated and generally stable. Avalanche danger assessment Avalanche danger is considerable above 2000 m, below that altitude danger is moderate. Main danger in all regions: fresh snow and snowdrifts. Danger zones occur in wind-impacted steep terrain, behind protruberances, in drifted gullies and bowls. Fresh snow + drifts are trigger-sensitive. Older snowdrift accumulations are blanketed over, thus difficult to recognize. Medium-to-large slab avalanches can be triggered by the weight of one single skier. Backcountry activities demand experience in assessing risks on-site and knowledge of local terrain. Naturally triggered loose-snow avlanches can become large at high altitudes, triggerable slabs are possible in heavily wind-loaded zones. Where fresh snow was deposited on grassy steep slopes that were bare (mostly below 2000 m in E-S-W aspects) the snowpack can glide over the ground. Glide cracks warn of this danger.
