Weather Forecast

On Sunday, cloud cover will dominate, visibility will often be limited. Intermittent sunshine, 10-20cm of fresh snow is anticipated. Rainfall level at 900m. At all altitudes, light winds will prevail. At 2000m: temperatures revolving around -4 degrees.

Danger expected to remain constant

Avalanche Activity

Covered snowdrift masses

Avalanche danger above 2000m is moderate, danger is low below that altiutude. The major risk stems from recent snowdrifts, near to and distant from ridgelines. Most of the avalanche prone locations occur on north- and east-facing slopes, they are almost impossible to recognize due to the new fallen snow, particularly wind-loaded gullies and bowls should be circumvented. Avalanches will be small, reaching maximally medium-size, they can fracture by minimal additional loading, large additional loading is more often necessary. As of 2600m on purely shady slopes there is a small persistent weak layer problem: isolated medium-sized avalanches can be triggered particularly by large additional loading.

Snowpack Structure

Atop the fresh snow and snowdrifts of recent days, loose and cold, fresh snowfall is expected, without much wind influence. The drifted masses of recent days will fracture mostly in the fresh fallen snow just below it or else at the uppermost melt-freeze crust. At high and high alpine altitudes, the September snow has persisted and now serves as a compact base. In places in transition zones from the September snow to the November snow, there are faceted crystals which can serve as a fracture surface. The snow is diversely distributed: broad and narrow ridges are often completely windblown, also in other areas the fresh fallen snow blankets the base insufficiently.
