Avalanche Activity

Mild westerly weather will deteriorate snowpack firmness, increasing wet loose-snow avalanches possible (small-to-medium)

Above the treeline avalanche danger is moderate, due to older snowdrifts. Danger zones esp. on NE/S facing slopes, esp. behind protruberances and at entries into gullies and bowls where snowdrift accumulations can trigger slab avalanches even by minimum additional loading (1 person). Mild temperatures and temporary rain impact will diminish snowpack firmness. Likelihood of wet-snow/glide-snow avalanches will increase. Danger zones esp. on steep grassy slopes at high altitudes and steep hillsides.

Snowpack Structure

Due to milder temperatures on Friday, then dropping on Saturday, the snowpack has gained stability. Solar radiation on Saturday afternoon also helped the snow to seettle on sunny slopes. Due to stormy winds on Sunday exposed slopes were windblown, on leeward high altitude slopes snowdrift patches were generated which are poorly bonded with the melt-freeze encrusted snowpack surface. On Monday the snow will become soft due to mild temperatures.

Weather Forecast

A powerful westerly air current will traverse the Eastern Alps in an Atlantic front, bringing relatively mild air masses our way. On Monday on the northern flank of the Alps, barrier clouds will bring snowfall/rainfall. Snowfall level will ascend from 1000 gradually to 1600 m. Particularly during the afternoon, isolated showers can extend to the southern flank, where there will also be some sunshine. At high altitudes, strong to stormy westerly winds will be blowing. At midday at 2000 m: +1 degree, at 1500 m, +3 degrees.On Tuesday, westerly weather with strong winds and mild temperatures. Summits mostly in fog, only occasional sunshine.

Tendency

Loss of snowpack firmness due to rain. Main danger wet-snow and loose-snow avalanches.
