Gliding snow, increasing high altitude drifts
Naturally triggering glide-snow avalanches over steep, grassy slopes below 2600 are still a threat at any time. Increasing snowdrifts in high altitude ridgeline terrain on east and south-facing slopes. Settled powder where no wind impact on north-facing slopes. Few danger spots, in transitions at high and high alpine altitudes. Inneralpine sunny slopes have melt-freeze, later corn snow. Wet-snow avalanches where solar impact is high.
Danger of avalanches is MODERATE all day long, the main problem stems from naturally triggered glide-snow avalanches which can release in steep, grass-covered terrain at any time below 2600 m, and sometimes grow to large size (usually not in backcountry ski terrain).
Clouds reduced outgoing radiation during the night, resulting in various crusts in the morning on sunny slopes, some breakable, all softening during the day. Wind-exposed terrain has hardened surfaces, elsewhere settled powder. Weak layers of thin faceted crystals or covered hoar in the old snow are seldom, triggerable generally by large additional loading. At high altitudes near ridgelines, fresh snowdrifts are forming which are prone to triggering. The deep snowpack is gliding over extremely steep, grass-covered slopes, new glide cracks are opening.
Alpine Weather Forecast (ZAMG Salzburg)
Adequate touring weather today, variable visibility, some sunny intervals, only the highest peaks hidden in fog. Above 2200 m a moderate wind will be blowing, stronger in Lungau and on the Main Alpine Ridge (50 km/hr). At 2000 m: -2 degrees; at 3000 m: -4 degrees.
Short Term Development
Strong winds and fresh snow, rainfall at low altitudes, will increase avalanche danger on Friday to CONSIDERABLE in places. Depending on altitude, the problem will be either gliding snow, wet snow or snowdrifts.
