The nights will be mostly clear in the north and partly cloudy on the southern flank of the Alps. During the day, it will be mostly sunny at high altitudes on both days. Visibility will be partly obscured by Sahara dust, particularly on Sunday. It will be partly cloudy in the Jura, along the Prealps and in the south. Isolated rain showers are possible, especially in the Jura. The zero-degree level will drop and will be around 2200 m in the north and 2000 m in the south. There will be mostly light south to southeasterly winds.
The danger of dry avalanches will continue to decrease, but only slowly in Grisons due to the weak snowpack structure. The danger of wet and gliding avalanches will increase somewhat during the course of each day. Touring and off-piste descents should be completed in good time.

"}, "avalancheProblems": [{"aspects": ["N", "NE", "E", "NW"], "comment": "Distinct weak layers in the old snowpack necessitate caution. Avalanches can be released by a single winter sport participant. They can be triggered in near-ground layers and reach large size. Isolated whumpfing sounds can indicate the danger. The avalanche prone locations are to be found in particular in areas where the snow cover is rather shallow and at transitions from a shallow to a deep snowpack. They are barely recognisable, even to the trained eye.In the regions north of a line from the Rh\u00f4ne to the Rhine and in the extreme west of Lower Valais, weak layers in the snowpack are mostly thickly covered and are now hardly triggerable by human activity.
In the regions south of a line from the Rh\u00f4ne to the Rhine, the persistent weak layers that have been relevant since the beginning of January are still present. However, the number of avalanche-prone locations has decreased significantly. Danger signs have still been observed in the last few days, particularly in Grisons, and dry avalanches have been triggered in deeper layers of the snowpack.
Weak layers in the lower part of the snowpack are being weakened as they become moistened for the first time. Wet slab avalanches are possible as the day progresses. These can occur naturally but can also be occasionally triggered by winter sports participants, at present mainly on sunny slopes below approximately 2600 m. Isolated gliding avalanches are also possible here.
