Covered snowdrift masses, fresh snowdrift accumulations in high alpine regions

Avalanche danger above 2000m is moderate, below that altiutude danger is low. 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 and 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, more often large additional loading is necessary. As of 2600m on purely shady slopes there is a small persistent weak layer problem: particularly by large additional loading, isolated medium-sized avalanches can be triggered.

Atop the fresh snow and snowdrifts of recent days, loose and cold, fresh snowfall is expected, without much wind influence. Only in high alpine regions can the NE winds generated fresh, small snowdrift masses. 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.

On Monday, heavy cloud cover and intermittent light snowfall will be the dominate weather factors. All in all, maximum 5 cm of fresh snow is anticipated. Winds will be blowing largely at light strength from the northeast, noticeable at most on the highest summits. At 2000m: temperatures around -7 degrees; at 3000m: -11 degrees.

Danger expected to gradually recede.
