Snowpack

With the mild weather, moisture penetration into the snowpack is well advanced. On south-facing slopes, the snowpack is moist up to around 3000 m, on east- and west-facing slopes up to 2500 to 2700 m, and on north-facing slopes up to around 2000 m. Initial moistening of near-ground weak layers is now reaching around 2200 to 2400 m on north-facing slopes, and 2800 m on west- and east-facing slopes, and it is especially on these aspects and at these altitudes that large and occasionally even very large wet slab avalanches may be triggered naturally. The weak layers in the old snowpack in Grisons in particular are the least deeply buried, and it is here that wet slab avalanches are most likely also to be triggered by human activity. Whumpfing sounds continue to be a possible indication of a weak snowpack.

At higher altitudes, where the snowpack is still dry, avalanches can in some places also still be triggered in the dry old snowpack or occasionally in layers closer to the surface.

Outlook to Monday

The night into Sunday will be mostly cloudy. During the day, it will be mostly heavily cloudy in the north with showers and thunderstorms on the northern flank of the Alps. The snowfall level will drop from 2200 to 1800 m. In Valais, Ticino and the Engadine, it will be partly sunny. The westerly wind will pick up. Overnight to Monday, it will be mostly clear in Valais, Ticino and the Engadine, while elsewhere it will be mostly cloudy. During the day, there will be variable cloud cover with showers along the central and eastern northern flank of the Alps. Elsewhere, it will be quite sunny.

The danger of dry avalanches will not change significantly. The danger of wet avalanches will increase, particularly in Valais, Ticino and Grisons as the day progresses. Tours and hut approaches should be completed in good time. In the other regions, isolated wet avalanches are possible at any time.
