Lechquellen Mountains

Fresh snow/drifts and wet-snow avalanches

Sunday will be very (foehn-generated) windy and mild, the zero-degree level will ascend to 3000 m. Sahara dust will create diffuse light conditions. Intermittently sunny. As temperatures continue to rise, danger of wet-snow avalanches will also rise during the course of each day. Backcountry skiing tours should begin early, end early.

Nocturnal hours: Clouds will disperse, skies clear or with only scattered clouds. Saturday daytime: Frequent sunshine, only few clouds. In the Silvretta the clouds will spread from the south. At 2000 m: -1 to +4 degrees. Moderate to strong southerly winds.

Fresh snow/drifts and wet-snow avalanches

Fresh snow and drifts can trigger a medium slab or loose-snow avalanche by 1 person in wind-loaded gullies and bowls, and behind discontinuities. Frequency and size of danger zones increase with ascending altitude. In case of extended bright intervals, medium-sized loose-snow avalanches are possible, possibly endangering exposed zones. Activities in outlying terrain demand experience in assessing avalanche dangers on-site. Danger rises during the course of each day due to warmth and solar radiation. Isolated glide-snow avalanches are possible. Increasing glide-snow avalanches on smooth grass-covered slopes which previously were bare. Avoid zones below glide cracks.

Fresh snow and drifts from previous days have settled and increasingly consolidated. Weak layers lie embedded in the latest fresh snow and drifts, these are prone to triggering. The snowpack is moist-to-wet down to the ground up to high altitudes. Because ski areas are closed there is little information about snowpack layering at high altitudes. At low and intermediate altitudes the lower layers of the snowpack are often wet, which reinforces gliding.
