Avalanche prone locations are found both near to and distant from ridgelines, at entries to gullies and bowls, and in general behind protruberances, mainly in N-E-S aspects. In the danger zones, a slab avalanche can be triggered even by minimum additional loading. The snowpack fundament is by and large stable, potential weak layers of faceted crystals or depth hoar are generally blanketed over by thick crusts. Since Sunday, several rounds of snowfall have brought up to 40 cm of fresh snow amid strong wind impact. Both inside the fresh snowdrifts and in transitions to the old snowpack, weak layers lurk embedded (surface hoar, loosely-packed fresh snow, graupel). On Tuesday, heavy snowfall is expected along the Main Alpine Ridge, most peaks will be shrouded in clouds. Stormy, icy-cold NW winds will be blowing (50-100 km/hr). At 2000 m: -10 degrees. On Wednesday, further snowfall in the barrier cloud regions of the north. Avalanche danger will increase somewhat due to snowdrifts. 2021-03-15T17:00:00+00:00 avalanche-warnings.eu 2021-03-15T23:00:00+00:00 2021-03-16T23:00:00+00:00 2 1 drifting snow above timberline Moderate avalanche danger due to fresh snowdrifts. New cornices forming! Moderate avalanche danger prevails above the timberline due to freshly generated snowdrifts. Avalanche prone locations are found both near to and distant from ridgelines, at entries to gullies and bowls and in general behind protruberances, mainly in N-E-S aspects. Triggering a slab avalanche in the avalanche prone locations is possible primarily by large additional loading, in isolated cases even by the weight of one single skier. The snowpack fundament is by and large stable, potential weak layers of faceted crystals or depth hoar are generally blanketed over by thick crusts. Up to 20 cm of fresh snow has been registered amid strong wind impact. Both inside the fresh snowdrifts and in transitions to the old snowpack, weak layers lie embedded (surface hoar, loosely-packed fresh snow, graupel). South of the Main Alpine Ridge it will remain dry for longer on Tuesday, clouds will disperse to some extent, although occasional snow showers cannot be ruled out in the Styrian rimline ranges. A stormy, icy-cold NW wind (50-100 km/hr) will be raging. At 2000 m: -10 degrees. No significant change in avalanche danger is expected. 2021-03-15T17:00:00+00:00 avalanche-warnings.eu 2021-03-15T23:00:00+00:00 2021-03-16T23:00:00+00:00 1 drifting snow thin, small snowdrifts Low avalanche danger prevails in general, but isolated danger zones occur due to fresh snowdrift patches Low avalanche danger prevails in general, in isolated cases freshly generated snowdrifts can be triggered as a small slab avalanche. Avalanche prone locations are found near ridgelines, behind protruberances in the landscape (small-spread), mostly in E-S aspects. The snowpack fundament is generally melt-freeze encrusted and stable. Since Sunday as a result of some fresh snow and storm-strength NW winds, small snowdrift patches have been generated which are poorly bonded with the base at high altitudes. South of the Main Alpine Ridge it will be dry for longer, clouds will disperse somewhat, occasional snow showers cannot be ruled out in the Styrian rimline ranges. A storm-strength, icy-cold NW wind (50-100 km/hr) will be raging. At 2000 m: -10 degrees. No significant change in avalanche danger is expected.
