Low avalanche danger but isolated danger zones from fresh snowdrifts
Low avalanche danger but isolated danger zones from fresh snowdrifts
Avalanche danger is generally low, but above the timberline on E/S facing slopes at entries into gullies and bowls and behind discontinuities there are isolated danger zones where 1 person can trigger snowdrifts and release a slab avalanche.
The snowpack base has consolidated due to lower temperatures and formed a melt-freeze crust at the transition to the fresh snow. Atop of it, 30 cm of fresh snow has been deposited since Sunday evening, partly transported to E/S facing terrain. The fresh snowdrifts may contain weak layers or could develop weak layers at transitions to the old snow.
In the northern barrier cloud regions between Dachstein and Hochschwab Massif, snow showers will move through repeatedly on Wednesday night, amid brisk NW winds. By Thursday, 10-15 cm of fresh snow is expected, in places up to 20 cm. On the southern flank of the Alps near the Fischbach Alps and Graz Mountains, 5-10 cm of fresh snow is expected. The southern mountains will be favored, hardly any precipitation is expected. At 2000 m: -7 to -5 degrees.
Weather will remain changeable and cool, along the northern flank of the Alps repeated bouts of snowfall. Avalanche danger levels are not expected to change significantly.
