Daytime loss of snowpack firmness up to high altitudes

Avalanche danger in early morning is LOW, then rises to MODERATE by midday. Isolated danger zones for slab avalanches occur in ridgeline E/S aspects at high altitudes and in wind-loaded gullies and bowls. There, with large additional loading (e.g. from a fall), a slab avalanche is possible.+ Naturally triggered wet loose-snow avalanches (also from addtional loading) are possible in sun-drenched steep terrain and isolated glide-snow avalanxches in extremely steep grassy terrain. These can reach medium size, in isolated cases large size.

Fresh snow and drifts from the weekend have settled well, the proneness to triggering (E/S) has receded. Steep sunny slopes have a melt-freeze crust capable of bearing loads in early morning, then softening up quickly during the daytime, depending on aspect and altitude. Subsequently, wet loose-snow avalanches (natural or triggered by skiers) are possible. Also some medium releases as glide-snow avalanches are conceiveable.

On Tuesday, following a night of frequently star-studded skies with a few clouds, it will be sunny. Winds will be light to moderate from S/SW. Warmer than in the last few days. At 2000 m: 6-8 degrees, at 3000 m +1 degree. On Tuesday night there will be good outgoing longwave radiation. Also on Wednesday, sunny, a few clouds, diffuse light conditions. Some southerly foehn wind in exposed terrain. At 2000 m: 10 degrees, at 3000 m: 2 degrees.

Due to significant warming, a pronounced daytime danger cycle of naturally triggered avalanche activity. Time management is crucial!
