Wet snow
- Alle Höhenlagen
Increasing wet-snow avalanches. Snowdrifts at high altitude.
Foehn wind will persist, though slacken off somewhat. Sunny despite Sahara dust and very mild. In the southern ranges, more cloud cover. Danger of wet-snow avalanches will also rise during the course of each day. Backcountry skiing tours should begin early, end early.
Nocturnal hours: Dry, mild, reduced nocturnal outgoing longwave radiation. Sunday daytime: High-altitude clouds, Sahara dust will hamper the sun somewhat. At 2000 m: +6 to +8 degrees. Strong to storm-strength southerly winds.
Increasing wet-snow avalanches. Snowdrifts at high altitude.
Increasing slides and small-to-medium wet-snow avalanches are possible, esp. in sunny steep terrain. Glide-snow avalanches persist. Avoid zones below glide cracks. Fresh small snowdrifts can trigger a slab avalanches in steep shady terrain above the treeline behind discontinuities and in wind-loaded gullies and bowls. Frequency and size of danger zones increase with ascending altitude. Activities in outlying terrain demand cautious route planning.
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, a thin melt-freeze crust often forms on the surface which then melts quickly. 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.
