Gliding snow
- All elevations
Avoid zones below glide cracks
Minor fresh snow + winds = fresh snowdrifts accumulating
Avoid zones below glide cracks
Avalanche danger is moderate up to 2600 m. Main problem: gliding snow. Glide-snow avalanches can trigger naturally up to 2600 m at any time of day, esp on steep slopes with smooth ground beneath (grass, rocks) in all aspects. They can be medium-sized. Avoid zones below glide cracks. Above 2600 m the dangers of falling outweigh those of avalanches. Weak layers in the old snow can trigger above 2800 m in a few places, usually by large additional loading (groups, cornice collapsing). Releases can be medium-sized. Danger zones increase with ascending altitude.
The snowpack at high altitudes shows harsh wind impact, snow is irregular. At low and intermediate altitudes the snowpack is moist/wet. Up to 2300 m there are rain seepage channels throughout the near-surface part. There are crusts up to 2700 m, also icy films near crusts. The intensifying southerly wind will not transport much snow, since it is hardened. A crust at intermediate and low altitudes can turn to firn on steep south-facing slopes. The ground is warm, thus, the entire snowpack is gliding downhill over smooth surfaces.
Only scattered clouds during the night, southerly winds will intensify at high altitudes, elsewhere only light-to-moderate. Foehn-impacted conditions, the sun north of the Alps will shine only through the veil of clouds, which will thicken as the day progresses. Southerly winds will be light-to-moderate. At 2000 m: +1 degree; at 3000 m: -5 degrees. On Sunday night, snowfall above 1000 m (5-15 cm of fresh snow).
