In case of rain showers, snowpack will lose its firmness

Avalanche danger below 1800m is moderate. Due to the rainfall, small wet loose-snow avalanches can be expected in very steep starting zones. Above 2000m in some places even one person can trigger a small, in seldom occurrences medium-sized slab avalanche. Danger zones occur on W/N/E facing steep slopes, often distant from ridgelines. Caution urged especially at entry points into very steep gullies and bowls. On very steep grass-covered slopes, isolated small glide-snow avalanches are possible.

On shady high-altitude slopes, small-area trigger-sensitive snowdrift accumulations lie deposited atop a faceted old snowpack. Elsewhere, after a night of much reduced outgoing radation, breakable melt-freeze crusts, quickly softening in case of solar radiation. Rain seepage is burdening the already heavily moistened snowpack.

During the nocturnal hours cloud cover will become more dense amid strong to storm-strength foehn winds. On Monday, many peaks will be shrouded in fog. In early morning, light-to-moderate rainfall up to 2000m. Above that altitude a few centimetres of fresh snow is anticipated. Ongoing strong-to-stormy southerly winds. At 2000m: 0 degrees; at 3000m: -5 degrees.

On Tuesday, after a night of often clear skies, melt-freeze crusts and firn on sunny slopes, elsewhere no change.
