On Tuesday and Wednesday, mostly clear nights will be followed by sunny daytime conditions and light winds. The zero-degree level will be around 2000 m.
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 somewhat as the day progresses.

South of a line from the Rh\u00f4ne to the Rhine, the persistent weak layers that have persisted 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.
With moistening of the snowpack on sunny slopes, some moist slab avalanches have been triggered by human activity in the weakly bonded old snow in recent days. This is particularly the case around the treeline in Grisons.
