Quite favorable conditions - daytime rise in danger of wet-snow avalanches

Overall quite favorable springtime conditions prevail, avalanche danger is low. Due to foehn mpact, small fresh snowdrift accumulations have been generated, these are prone to triggering. Isolated avalanche prone locations occur on shady, steep ridgeline and pass slopes and behind protruberances, and in transitions from shallow to deep snow above 2400 m, particularly in laterally-skied steep terrain, mostly by large additional loading they can trigger locally. Due to daytime warmth and solar radiation, glide-snow avalanches are possible, especially below 2200 m on steep sunny slopes.

Due to SE/SW winds, generally small-sized fresh snowdrift accumulations have been generated. Especially in the classic foehn zones in the southern regions, these avalanche prone locations are more frequent. Bonding of drifts to the old snowpack is poor on shady slopes, they are prone to triggering (the upper part of the snowpack there is soft, faceted crystals blanket the surface). On sunny slopes a crust capable of bearing loads is evident, but this softens up during the daytime due to solar radiation and higher temperatures, which in turn enhances the gliding movement of the snowpack over very steep grass-covered slopes.

A sunny day in the mountains, accompanied by some high-altitude cirrus clouds. The foehn in classic foehn-exposed zones and on summits is the only disturbance. At 2000 m: -4 to +2 degrees. Mostly moderate S/SW winds at high altitudes.

The Weather Service forecasts quite sunny weather for the next few days, with moderate foehn influence and milder temperatures, i.e. already springlike conditions. Low avalanche danger in the mornings, slight rise of wet-snow avalanche danger during the daytime.
