The avalanche risk is considerable above 1800 metres and low below. The situation remains precarious for winter sports. On slopes of all aspects, medium-sized slab avalanches can easily be triggered by individuals in some places. It is highly likely that surface-triggered avalanches will tear through to deeper layers. In particular on north-west to north to east-facing slopes above 1800 metres. 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.

Another 10 to 20 cm of new fallen snow, even more in places. This, and the snow of the past few days, is extensively transported and is very prone to triggering. Fresh and older wind slab snow overlaid with soft layers of faceted crystals and deep rime. In wind-protected areas, on shady slopes above around 2000 m and 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 overall snow depths that are well below average.

It will be cloudy with snow showers during the night. The amount of new snow will be 5 to 10 cm, with the most snow falling in the northern Alps. The wind is blowing briskly from westerly directions with gusts of around 60 km/h, on the main ridge even around 80 km/h. The wind may reach into the valleys at times. Visibility will be poor on Tuesday. Clouds and fog will dominate and it will snow, sometimes heavily and for longer periods. During the day it will snow 10 cm to 20 cm, with snowfall levels around 600 metres. The wind will continue to blow briskly to strongly from westerly directions. At 2000 m around -8 degrees, at 3000 m around -15 degrees.

Snowdrift accumulations remain prone to triggering, the persistent weak layer problem remains.
