update 14.02.18 7:10 (Bernhard Niedermoser - translated by Jeffrey McCabe)
Avoid very steep zones. Southern aspects more favourable.
Weak layers beneath the loosely-packed powder and drifts complicate the situation. Most danger zones on W-N-E facing slopes. Settling noises, isolated triggerings indicate a weak snow base. Avoid steep transitions, typical leeward slopes, triggerings esp. with large additional loading, but sometimes even the weight of one skier is enough.
The situation demands much caution, restraint and experience. Avalanche danger above the treeline is CONSIDERABLE (3), in the Nockberge, Osterhorn range and most of the Niedere Tauern danger is MODERATE (2).
The fresh snow from Monday is cold and loosely-packed, the later snowfall that day fell without wind influence. The lower batch of the fresh snow is bonded, fell amid wind impact. Bonding is highly varied, but prone to triggering. On south-facing slopes, the snowpack is better; on extended north-facing slopes (W-N-E) a mixture of hoar and faceted, old powder snow crystals and thin old snowdrift accumulations from recent days.
Alpine Weather Forecast (ZAMG Salzburg)
The day will begin with cloudless skies. Towards the west and south it will stay that way. Further east, esp. Osterhorn range, Tennen range, Dachstein, possibly also Niedere Tauern, low lying clouds will move in this afternoon. Hardly any wind, cold. At 2000 m: -12 degrees; at 3000 m: -18 degrees.
Short Term Development
The snowdrift situation above the treeline will remain the major risk. Following the most recent snowfall, the proneness to triggering has receded a notch. However, the NW winds in the afternoon will generate new snowdrift accumulations. Danger levels for Thursday and Friday will be from MODERATE to CONSIDERABLE (due to the newly arising winds).
