Caution: freshly generated snowdrift accumulations at high altitudes
Fresh snow and drifts are triggerable esp. on steep shady slopes. One sole skier can trigger a small-to-medium loose-snow or slab avalanche. Apart from the danger of being buried in snow masses, the risks of being swept along and forced to take a fall require adequate caution. On steep grass-covered slopes with sufficient snow on the ground or atop smooth ground, isolated small-to-medium glide-snow avalanches are possible. In rocky terrain, increasingly frequent slides and small loose-snow avalanches are possible.
The fresh snow which has fallen since Thursday has in the interim settled and increasingly consolidated at intermediate altitudes due to solar radiation. On steep slopes it is still loose and soft. Fresh snow and small drifts lie deposited on shady slopes atop expansively metamorphosed, soft layers, often blanketing graupel, bonding only moderately good. The below average snowpack is well consolidated. On sunny slopes and at lower altitudes the fresh snow will fall on bare ground.
Clouds will continue to thin out during the nighttime hours. Clear skies and especially cold at high altitudes. On Tuesday, unhampered sunshine all day long, outstanding visibility, the zero-degree level rising as the day unfolds. At 2000m. -6 to 0 degrees. Light E/NE winds at high altitudes.
Receding danger of dry-snow avalanches. Due to daytime warmth, increasingly frequent wet-snow avalanches.
