Avalanche Activity

Heed trigger-sensitive snowdrifts, attentiveness towards glide-snow avalanches

In the morning hours, favourable conditions prevail, avalanche danger is low. Fresh, mostly small snowdrifts are still trigger-sensitive on steep shady slopes and can be triggered in isolated cases. Danger zones occur mostly on shady steep ridgeline slopes, in gullies and bowls and behind abrupt discontinuities in the terrain. At intermediate altitudes isolated glide-snow avalanches are possible on smooth steep sunny grass-covered slopes due to rising temperatures during the daytime.

Snowpack Structure

The snowpack was able to settle due to solar radiation and higher temperatures, and consolidate. Mostly small snowdrift accumujlations can be trigger-sensitive on high altitude shady slopes. In some shady terrain there is still powder, on sunny slopes mostly wind-crusts or melt-freeze crusts which soften during the daytime. Glide cracks indicate imminent danger.

Weather Synopsis

Nocturnal hours: following a partly cloud night, in places with high fogbanks, dense clouds will move in from the north. It will remain dry. Temperatures: -2 to +2 degrees. Friday: From the northeast, moist and cloud-filled air masses will move our way, fog will be prevalent towards the north, the higher peaks of the Silvretta could jut out of the fog. No precipitation is anticipated. At 2000 m: -4 degrees. Moderate to brisk NE winds.

Tendency

The weekend will be mostly sunny, which will stabilise the snowpack and the snowdrift accumulations. The danger of wet-snow avalanches will increase during the course of the day.
