Avalanche Activity

Tours require restraint, observe multiple starting zones.

The avalanche risk is considerable above the tree line and low below. The situation is precarious for winter sports. On slopes of all aspects, medium-sized slab avalanches can easily be triggered by individuals in some places. In particular on north-west to north to east-facing slopes above 1800 m, avalanches triggered on the surface can tear through to deeper layers and become large. Danger areas are sometimes barely recognisable and require a defensive choice of route. Be careful in particular near transitions from little to much snow, behind terrain edges, in the entrance areas to steep gullies and bowls and also in the forest boundary area or in forest aisles. Remote triggering is possible and naturally triggered avalanches can also occur.

Snowpack Structure

In the past few days, around half a metre of new fallen snow has been transported extensively and is very prone to triggering. Fresh and older, over-snowed wind slab snow overlay soft layers of faceted crystals and deep rime. In wind-protected areas, on shady slopes above about 2000 m, on sunny slopes above 2400 m, surface hoar has also been snowed in in places. Fractures occur either in soft layers near the surface or around the crust that forms the transition to the completely angular old snowpack. In general, areas with little snow alternate with sometimes considerable snowdrift accumulations in a confined space with below-average overall snow depths.

Weather Forecast

Further snow showers (10 cm) during the night. The wind blows strongly from west to north-west. On Wednesday, visibility will be good until midday and the sun will shine frequently. In the afternoon, the clouds will thicken and high peaks may become foggy. It will snow a little in Pinzgau. The wind will blow moderately from west to south. Warming during the day. At 2000 m -10 to -4 degrees, at 3000 m -16 to -9 degrees.

Tendency

The avalanche danger will increase on Thursday with new fallen snow and wind.
