Avalanche Activity

Glide-snow avalanches on extremely steep grass-covered slopes

Avalanche danger is MODERATE. Where snow is sufficient, small glide-snow avalanches can release naturally cases in extremely steep terrain (>40°), especially where the ground was previously bare of snow. Avoid zones below glide cracks. Loose-snow avalanches can in isolated cases in extremely steep terrain (>40°) release naturally or by 1 person due to radiation, releases small.

Snowpack Structure

Loose snow on the surface can lose bonding through solar radiation, but radiation also helps the snowpack to settle. Blanketed fresh snow or graupel can be a near-surface weak layer. As a result of solar radiation, bonding is generally good. Atop snowy steep rocks and grassy slopes the snowpack is wet at ground level and can glide away.

Weather Forecast

Nighttime skies will be clear. On Friday, initially good visibility and sunshine, but heavy cloud layers will move in during the morning from the southwest, making the light diffuse. Peaks should remain in the clear, foehn-generated bright intervals are possible. In the Northern Alps more pleasant. Winds light. At 2000 m: -2 degrees.

Tendency

Due to higher temperatures the snowpack will moisten, the wet-snow problem will increase.
