Danger of wet avalanches even in the morning. Caution on very steep shady slopes in high-alpine zones.

Danger of wet avalanches even in the morning. Caution on very steep shady slopes in high-alpine zones.

Following a mild night with overcast skies and reduced outgoing radiation, moderate danger prevails. Naturally triggered wet-snow and glide-snow avalanches can be expected, reaching medium size in high-altitude starting zones. Wet-snow avalanches can be triggered by persons in steep terrain. Due to rainfall, danger below 2400m could rise somewhat. Fresh snowdrifts require attentiveness in very high ridgeline terrain. In addition, the old snowpack can be triggered by large additional loading in extremely steep terrain. Backcountry tours demand a cautious route selection. At high altitudes, fresh snowdrifts require attentiveness.

The snowpack can’t consolidate well in the warm, cloudy nights, esp. on E/S/W-facing slopes up to high-alpine zones and on shady slopes below 2200m. The air is becoming moister, the old snowpack is thoroughly wet up to high altitudes. Due to rainfall below 2400m the snowpack is being additionally weakened. Brisk foehn winds are generating mostly small snowdrift accumulations in high ridgeline terrain. In shady wind-protected zones the uppermost layers are often soft.

Compact clouds will pass through, the summits could become shrouded in fog, light conditions become diffuse. Showers possible. esp. in the northern massifs, snowfall above 2400m. It will remain mild. At 2000m: 4 degrees. Initially brisk S/SW winds, slackening off later in the day.

On Monday afternoon, short rain showers, snowfall level at 2600m, are possible. Danger of wet-snow and glide-snow avalanches persists.
