Gliding snow
- All elevations
Slightly increasing avalanche danger at high altitudes. Glide-snow avalanches persist.
Slightly increasing avalanche danger at high altitudes. Glide-snow avalanches persist.
Avalanche danger is moderate. Continuing wet-snow and glide-snow avalanches are possible in the morning, esp. on sunny slopes but also on shady slopes, they can become medium-sized, even large-sized, if avalanches fracture down to more deeply embedded layers of the snowpack Backcountry tours and ascents up to huts should be terminated early in the day. In high-alpine regions the danger of dry-snow avalanches in the morning is low, later rising with fresh snow and winds. Esp. in ridgeline terrain and wind-loaded gullies and bowls, fresh drifts are prone to triggering and easily released. Cornices can still break or collapse.
Below 2500 m the old snowpack is thoroughly moist and wet down to the ground. The surface freezes at night depending on cloud cover andthus, nocturnal outgoing radiation is insufficient to consolidate it, only a thin melt-freeze crust can form which then quickly softens. Due to strong warmth impulse, the snowpack rapidly loses its firmness in the morning hours and weakens the snowpack.

Wednesday will be variably cloudy with light snowfall at 1000 - 1400 m. In afternoon the snowfall will taper off, towards evening the clouds will disperse. Danger of dry-snow avalanches will not change significantly. Danger of wet-snow avalanches will recede noticeably. Glide-snow avalanches remain unpredictable.
