Tendency

Sunshine and mild temperatures generating a daytime rise in avalanche danger

Avalanche Activity

Caution in little-tracked shady steep terrain. Beware small snowdrifts.

Near-surface weak layers are often still prone to triggering, esp. on little-tracked steep shady slopes. On shady steep high-altitude slopes and in ridgeline terrain, small-area snowdrift accumulations require caution. One sole winter sports enthusiast can trigger mostly small slab avalanches in these zones. 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, isolated medium-sized glide-snow avalanches still possible.

Snowpack Structure

Fresh snowfall is expected (5cm) which will be deposited up to high altitudes atop a weak old snowpack surface, it will bond well. In high-altitude ridgeilne terrain, small drifts will be generated. Below 1500m there is little snow on the ground. On shady slopes at high and high-alpine altitudes the older drifts lie atop an unfavorable old snowpack, which are often still prone to triggering.

Weather Forecast

In high-alpine regions, the sun will rapidly prevail against the early fogbanks and residual clouds. Elsewhere clouds will disperse more slowly, clouds and fog esp. persistent along the mountainside flanks, even into afternoon. At 2000m: -3 to 0 degrees. Brisk to strong E/NE winds.
