Avalanche Activity

Little snow, isolated glide-snow avalanches

Avalanche danger is low. On steep smooth slopes in all aspects, small glide-snow avalanches aer possible in zones which have not yet dischafged. Glide cracks should be circumvented. No prevalent problem for dry-snow avalanches. Small avalanches can be triggered in extremely steep terrain, mostly by large additional loading. Apart from the danger of being buried in snow, the risks of being forced to take a fall need to be taken into consideration. A cautious route selection is advised.

Snowpack Structure

Little snow on the ground. Often the crust is capable of bearing loads, but softens up during the course of the day. Many surfaces are wind-hardened or icy. The snowpacks up to intermediate altitudes is moist down to the ground, which enhances the snowpack gliding downhill over smooth ground surfaces.

Weather Forecast

Nocturnal hours: Clear skies, dry, good outgoing radiation. Wednesday daytime: A sunny and mild day, merely thin clouds above summit level. At 2000 m: +6 degrees. Moderate to brisk W/SW winds.

Tendency

Thursday morning will be sunny but have diffuse light conditions. The danger of dry-snow avalanches is not expected to change significantly. Danger of glide-snow avalanches will persist.
