Generally low avalanche danger
Generally low avalanche danger
Low avalanche danger in general, but attentiveness urged towards snowdrift patches in landscape concavities which are poorly bonded with the snowbase beneath them, in these danger zones isolated small slab avalanches can be triggered. In shady terrain above the timberline there is a persistent weak layer. Slab avalanches cannot be ruled out. Caution urged towards the peril of falling on icy surfaces.
At high altitudes the surface is hardened and icy or wind-pressed, beneath that the fundament is compact and without avalanche-relevant weak layers. Above 1500 m on shady slopes the snowpack is metamorphosing expansively, the snowpack consists of more and more faceted crystals, it is forfeiting its firmness and losing its base.
On Thursday morning, extensive sunshine in some regions, clouds will increase by the hour and in the afternoon heavy cloud cover will dominate. Summits will remain free until sundown. The W/NW winds will intensify during the daytime, reaching storm strength in exposed terrain. Temperatures will rise: 0 degrees at 2000 m at midday.
Avalanche danger is expected to remain low.
