Avalanche Activity

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.

Snowpack Structure

At high altitudes 15-25 cm of fresh snow was registered by Friday evening. During the night and on Saturday, another 10cm is expected regionally, accompanied by moderate-velocity winds which will deposited fresh snowdrifts atop soft layers on shady slopes, often with blanketed 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.40

Weather Forecast

NIghttime skies will be gray with intermittent rainfall, snowfall above 700-1000m. On Saturday, dense cloud cover will dominate with intermittent fog, limiting visibility repeatedly. In morning, widespread snow snowers, in afternoon drier. At 2000m: -3 degrees. Mostly light southerly winds at high altitudes.
