Glide-snow avalanches on extremely steep grass-covered slopes

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. Small drifts can be triggered by 1 person in high ridgeline terrain or release as a small slab. Danger zones occur on steep shady slopes. The dangers of falling outweigh those of snow masses.

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.

On Wednesday night, minor snowfall in the Northern Alps, later skies will clear from the northwest. On Thursday, scattered clouds, intermittent sunshine, some peaks can disappear in fog. Brisk westerly winds (up to 50 km/hr in Northern Alps) later slackening off. Occasional snow showers, not much snow will result. In afternoon, dry, clouds dispersing. At 2000 m: between -8 and -4 degreees.

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