Snowdrifts, gliding snow, wet snow
Some fresh snow atop a moist surface, at high altitudes atop hardened surface. At low altitude the snow is thoroughly wet. Fresh snowdrifts on high altitude Northern Alps slopes from W/NW winds and older drifts on north-facing slopes. Elsewhere, main problem: gliding avalanches and loosely-packed wet-snow avalanches, released artificially or naturally.
Avalanche danger is generally MODERATE (2). The reasons: fresh snowdrifts from W/NW winds, gliding snow and loss of snowpack firmness during the day.
The snowpack is thoroughly wet at low altitudes, it has no further reserves of cold. Above 1000 m there has been 5-10 cm of fresh snow registered, also some graupel. The snowpack is at least superficially moist up to 2500 m. In wind-exposed high altitude terrain (mostly in the Northern Alps, in isolated spots of the Tauern) the W/NW winds have transported the fresh snow; elsewhere there was little wind impact. Up to 2300 m, increased gliding snow masses were observed yesterday.
Alpine Weather Forecast (ZAMG Salzburg)
This morning, visibility is often impeded by snow showers and cloud. This afternoon, the cloud will disperse, visibility improve. Temperatures at 2000 m will be between -6 and -3 degrees; at 3000 m; -12 degrees. This morning, strong westerly winds will be blowing (gusts up to 50 km/hr), then slacken off during the afternoon.
Short Term Development
Tomorrow, fresh snowdrifts generated by stormy southerly winds. Daytime loss of snowpack firmness due to higher temperatures.
