Snowpack temporarily weakening due to rain impact

Snowpack temporarily weakening due to rain impact

Fresh and older snowdrift accumulations can be triggered even by one sole skier. Danger zones occur particularly on steep shady slopes, in wind-loaded gullies and bowls, and behind protruberances in the terrain. Size and frequency of danger zones tend to increase with ascending altitude. Where there has been rain impact, slides and, on steep grassy slopes, small glide-snow avalanches are possible. Caution urged below glide-cracks.

The fresh snow and drifts lie deposited atop an unfavorable, expansively metamorphosed old snowpack surface, often atop surface hoar, on shady slopes in particular. Also inside the snowdrifts themselves there are frequently trigger-sensitive intermediate layers evident. On sunny sloppes, bonding to the old snowpack surface is better. Due to rain impact the snowpack will temporarily be weakened.

Cloudy skies at night with increasingly heavy precipitation, initially falling as snow below 600m. At high altitudes, milder. The snowfall level will ascend in the latter part of the night to nearly 1500m. On Sunday morning a warm front will bring light rainfall to over 2000m. In the afternoon, dry, pleasant, mild. At 2000m: 0 to +5 degrees. Strong to stormy W/SW winds at high altitude.

Avalanche danger levels not expected to change significantly
