The nights will be partly clear. However, the cloud cover is uncertain due to the Sahara dust. On Saturday, it will be quite sunny despite cirrostratus clouds and obscured visibility due to Sahara dust. On Sunday, it will be increasingly cloudy in the south. There will be cumulus clouds in the Jura and along the Prealps. Otherwise it will remain quite sunny. On Saturday, the zero-degree level will be around 2700 m in the north and 2200 m in the south. On Sunday, it will drop by around 200 m. The winds will be mainly light.
The danger of dry avalanches will continue to decrease, but only slowly in Grisons due to the weak snowpack structure. Each day, the danger of wet avalanches will increase as the day progresses. Where outgoing longwave radiation has reduced during the night, the danger will increase in the morning. Touring and off-piste descents should be completed in good time.

"}, "avalancheProblems": [{"aspects": ["N", "NE", "E", "NW"], "comment": "Distinct weak layers exist in the bottom section of the snowpack. Avalanches can be released by a single winter sport participant. Caution is to be exercised in particular in areas where the snow cover is rather shallow, as well as at transitions from a shallow to a deep snowpack. Avalanches can be triggered in near-ground layers and reach large size. Isolated whumpfing sounds can indicate the danger.In the regions situated north of a line Rh\u00f4ne-Rhine and in the extreme west of Lower Valais, weak layers in the snowpack are mostly thickly covered and are hardly triggerable by human activity.
In the regions situated south of a line Rh\u00f4ne-Rhine, the persistent weak layers that have been a feature since the beginning of January are still present. However, the number of avalanche-prone locations has decreased significantly. Reports of avalanches and alarm signs indicate that the situation in Grisons remains the most precarious.
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 triggered by winter sports participants, at present mainly on sunny slopes below approximately 2800 m.
