Triggering a small-to-medium slab avalanche is possible in the fresh drifts, even be minimum additional loading. Fresh snow on sunny slopes is being deposited on rough melt-freeze crusts (below 1600 m on bare ground), in wind-exposed west-and-east facing terrain atop melt-freeze crusts, on north-facing slopes above 1800 m atop old, mostly dry powder. Bonding to the base is generally good. Potential fracture lines for slabs are likeliest in blanketed fresh powder, but will rarely be large-spread. The old snowpack has settled well, is generally stable. More deeply embedded weak layers of faceted crystals are sufficiently covered-over. Low, heavy cloud will hamper visibility on Friday, moderate snowfall, sometimes with graupel is expected (snowfall level descending from 1200 m in early morning). All in all, 10-20 cm of fresh snow is expected by Friday evening. Winds will be blowing at 40-60 km/hr from NW to N, bringing ever-colder air masses as the day unfolds. At 2000 m: -8 to -6 degrees in the afternoon; at 3000 m, -14 degrees. Moderate snowdrift problem on Saturday. In sun-drenched extremely steep terrain, some naturally triggered small loose-snow avalanches will be possible. 2021-03-04T17:00:00+00:00 avalanche-warnings.eu 2021-03-04T23:00:00+00:00 2021-03-05T23:00:00+00:00 2 1 drifting snow near ridgelines, forest zones, in gullies, steep bowls Avoid fresh snowdrifts and wind-protected fresh snow on hard base Danger above 1600 m is MODERATE, danger zones prevail in ridgeline steep terrain, in steep gullies and bowls, esp. on NW-E-SW slopes.

All in all, 10-20 cm of fresh snow is expected by Friday evening (locally up to 30 cm).

Isolated avalanche prone locations are found in extremely steep ridgeline terrain or very steep gullies, but mostly the danger of falling outweighs that of being buried in snow. Glide-snow avalanches on steep grassy slopes are unlikely, most danger zones have already discharged. Minor snowfall will be deposited atop hardened wind-crusts and melt-freeze crusts, up to intermediate altitude on bare ground, on north-facing slopes also on old, mostly dry powder. Area-wide weak layers hardly exists, the old snowpack is stable. Amid strong N/NW winds (40-60 km/hr) clouds and sunshine will change places repeatedly. Most of the time it will remain dry, intermittent light snow showers could spread this far from the north. Temperatures will drop: at 2000 m, -6 degrees in the afternoon. No significant change. Small loose-snow slides of the frsh snow are possible on sun-drenched steep slopes.
