Slightly rising danger due to snowdrifts above the timberline
Fresh snowdrift accumulations in ridgeline terrain and behind protruberances in the landscape can easily be disturbed. Other isolated danger zones are located in extremely steep, predominantly shady terrain. In isolated cases, small avalanches can be triggered in these places in the old snow. Such danger zones are located particularly in transitions from shallow to deep snow, for example, at entry points into gullies and bowls. Apart from the risks of being buried in snow masses, the danger of being swept along and forced to take a fall also require caution.
About 5-10cm, locally up to 15cm of fresh snow and small-sized fresh snowdrift accumulations have been deposited on top of a generally well consolidated, predominantly melt-freeze encrusted old snowpack surface. In some places, surface hoar was blanketed by the fresh snowfall. Particularly on steep shady slopes, weak layers in the old snow still persist in places. Overall there is little snow on the ground.
In the morning hours, sunshine will dominate, on foehn-exposed mountains the southerly winds will gradually intensify. Towards midday, high-altitude cloudbanks will push the sun into the background. At high altitudes, temperatures will rise measurably. At 2000m: -5 to +2 degrees; at 3000m: -8 to -3 degrees. Moderate to brisk southwesterly winds at high altitudes, gusts reaching strong velocity in the foehn-exposed mountain regions.
Avalanche danger levels are not immediately expected to change significantly.
