Avalanche Activity

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

Quite favorable conditions reign overall. Isolated avalanche prone locations occur on steep shady ridge slopes and behind protruberancees, as well as in transitions from shallow to deep snow above 2400 m, where isolated snowdrift accumulations generated over the last few days can still be triggered, mainly by large additional loading. Caution also urged towards large cornices. On steep sunny slopes, predominantly small-sized loose-snow avalanches can trigger naturally. As a result of daytime warming and solar radiation, glide-snow avalanches are possible on steep sunny slopes below 2200 m more than anywhere else.

Snowpack Structure

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.

Weather Synopsis

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.

Tendency

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.
