Avalanche Problem
Persistent weak layer
2400m


Weak layers in old snow require attentiveness.

Avalanches can be triggered in the weak old snow even by one single skier, esp. on shady slopes abovbe 2400m in transition zones into gullies and bowls. Avalanches are often medium-sized. Frequency and size of danger zones tend to increase with ascending altitude. In addition, fresher snowdrift accumulations on NW/N/E facing slopes are still prone to triggering, particularly on shady, wind-protected slopes.

Due to higher temperatures, isolated loose-snow avalanches will be possible during the course of the day, particularly on extremely steep sunny slopes, especially along the Salzburg border in case of extended bright intervals.

Snowpack

dp.1: deep persistent weak layer

Strong-velocity winds have intensively transported the fresh and old snow. At intermediate levels of the old snowpack on shady, wind-protected slopes there are faceted, metamorphosed weak layers. Weather conditions are reinforcing a gradual consolidation of the snowpack on SE/S/SW facing slopes, particularly above 2600m. At all altitudes there is too little snow on the ground for this juncture of the season. The snowpack is highly irregular over small areas.

Tendency

Avalanche danger levels will gradually recede.
