Caution: small-area drifts at high altitudes
Fresh snow and drifts are trigger-sensitive esp on shady steep slopes, small-to-medium avalanches can be triggered by winter sports enthusiasts in steep terrain. 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, increasingly frequent small-to-medium glide-snow avalanches are possible.
At high altitudes, 10-20 cm of fresh snow is expected by Thursday evening, locally up to 30cm, to be deposited by strong-velocity S/SW winds as fresh snowdrifts atop soft layers on shady slopes, often with blanketed graupel, bonding only moderately good. The highly diverse snowpack is well consolidated. Below 1500m there is little snow on the ground. On sunny slopes and at lower altitudes the fresh snow will fall on bare ground.
Gray skies, wet conditions at night, snowfall level initially at 1100-1400m, in early morning at 1100-700m. On Thursday the peaks will be shrouded in fog, snow showers will pass through (800-1100m). At 2000m: -2 degrees. Moderate-to-brisk S/SW winds.
No significant change expected before the next major precipitation
