Caution: fresh snowdrift patches behind protruberances, in gullies, bowls
Avalanche danger is low. Isolated avalanche prone locations are caused by trigger-sensitive snowdrift patches, particularly in E/S aspects behind protruberances, in gullies, bowls. In these places a medium-sized slab avalanche can be triggered by one sole skier. Near summits the surface is hard/icy. Beware: danger of falling.
The old snowpack is generally stable, there is a superficial melt-freeze crust on top. Since last Thursday there have been several bouts of snowfall, initially quite moist, then colder by Sunday morning. With the rising W/NW winds, new snowdrift accumulations were generated, also distant from ridges behind protruberances - these are prone to triggering. Exposed summit and entry zones, on the other hand, are utterly windblown, hard, icy. Beware: danger of falling.
From the west, dry and much milder air masses are moving towards the Eastern Alps. On Monday on the northern flank of the Alps, an intermediate high-pressure front will have a weak effect, while the southern regions are still under the influence of a weak low. Along the Northern Alps and the northern flank of the Tauern, skies will clear tonight, the sun will be evident from early morning. On the southern flank of the Alps, cloud will be more tenacious, only in the course of the morning will they begin to disperse, latest in the Gurktaler Alps region. Winds will be westerly, blowing at light to moderate strength. Temperatures will rise noticeably. At midday at 2000 m: -5 degrees, at 1500 m 0 degrees. On Monday night a frontal zone will reach us, dominated by lots of clouds, very little sunshine, strong winds. Occasional minor precipitation is expected, falling as snow above 1500 m.
The recently generated snowdrift accumulations will quickly settle amid solar radiation.
