Avalanche Activity

Mostly moderate danger due to fresh snow and small drifts

Fresh snow and drifts on high shady slopes and at high altitudes are prone to triggering. Danger zones occur near ridges, behind discontinuities and in wind-loaded gullies and bowls. Small-to-medium slab avalanches and also loose-snow avalanches can be triggered by 1 person. Such danger zones increase with ascending altitude. In backcountry terrain, a cautious route selection is imperative. On very steep and rocky slopes, slides and loose-snow avalanches can be expected during the course of the day due to solar radiation. Glide-snow avalanches can trigger at any time of day or night and grow to larger size.

Snowpack Structure

25-30 cm of fresh snow has been registered at high altitudes, amid moderate winds, which generated fresh small snowdrift accumulations, bonding well with the old snowpack surface. Older drifts were blanketed. The old snowpack is compact and stable, at low and intermediate altitudes wet down to the ground.

Weather Forecast

Nocturnal hours: Dry, scattered clouds. Thursday daytime: Sunshine often hampered by clouds, but visibility generally adequate. Zero-degree level rising to 2700 m. At 2000 m: -3 to +5 degree. Light westerly winds.

Tendency

On Friday, widespread cloudbanks, mild, hardly any wind. On Saturday, a cold front will bring some snowfall above 1700 m. Avalanche danger levels are not expected to change significantly.
