Avalanche Activity

Small-sized snowdrifts require caution

Avalanche danger at high altitudes is moderate, danger below that altitude is low. In ridgeline terrain, in gullies and bowls, freshly generated snowdrift accumulations require high caution. They are mostly small-sized, but poorly bonded with the old snowpack and thus, prone to triggering, small - in isolated cases medium-sized - avalanches can be triggered by one sole skier. Danger of glide-snow avalanches still persists, but diminished due to lower temperatures.

Snowpack Structure

Only a few cm of fresh snowfall, to be transported at high altitudes together with the fresh snow from Thursday. Fresh snowdrifts will accumulate. The latest batch of fresh snow lies deposited atop a well-consolidated, often melt-freeze encrusted old snowpack, following a period of lower temperatures. Only isolated small glide-snow avalanches possible.

Weather Forecast

Nighttime skies will be heavily clouded, accompanied by light snowfall. In the latter part of the night, clouds will disperse. On Saturday, sunshine will reign. At 2000m: -11 degrees. Moderate to strong-velocity NW/NE winds at high altitudes.

Tendency

No significant change expected in avalanche danger levels.
