Only isolated, small-area danger zones on very steep wind-loaded shady slopes

Avalanche danger is low. Triggering a small slab is possible in only few places, most endangered are shady slopes in very steep terrain above 2000m. In isolated cases a small glide-snow avalanche is possible.

About 5-10cm of fresh snow is anticipated on shady slopes above 1800-2000m, deposited often atop a loose old snowpack surface. In places the surface hoar will be blanketed. The old snowpack is weak, but doesn’t tend towards fracture propagation since the requisite slab is lacking. On shady slopes that are wind-protected there is loose snow. On sunny slopes the layering of the below-average snowpack is stable, and gliding over smooth ground has seldom been observed.

On Thursday, visibility will deteriorate during the course of the day from the north, first the Northern Alps will disappear in fog, in the afternoon hours showers will extend to most of the mountain massifs and visibility worsen. By Thursday evening, up to 10cm of snowfall expected. Moderate to brisk westerly winds. At 2000m: from -6 to -3 degrees; at 3000m: -9 degrees.

Avalanche danger levels expected to increase slightly by Friday evening due to 10-20cm of fresh snow
