Snowpack

The snowpack is quite favourable over widespread areas in the north, with only very occasional avalanches still being triggered in near-surface layers of the snowpack. In southern Valais, Ticino and Grisons, there are faceted layers deeper in the snowpack. A few avalanches have been triggered in the old snowpack in recent days, especially from the Davos region via the Engadine to Val Müstair, and occasionally also on the Main Alpine Ridge in Valais. With the northerly wind, small wind slabs formed locally at higher altitudes on Sunday.

With the warmth and sun, the snowpack is increasingly being saturated with water. On southern slopes, the snowpack is water-saturated up into the high Alpine regions, while on eastern and western slopes the majority is water-saturated up to around 2800 m. North-facing slopes are water-saturated to around 1800 m, with the surface moist up to around 2500 m. In areas with weak snow layering, moist slab avalanches can be triggered by people in some places.

A strong melt-freeze crust will form during the night into Monday. As daytime temperatures rise in the sunshine, this will soften as the day progresses and the risk of wet and gliding avalanches will increase.

Weather forecast to Monday

After a mostly clear night, it will be sunny on Monday. In the far south, it will be only partly sunny with patches of high stratus-like clouds in the late morning.

Weather review for Sunday

It was mostly sunny.

Fresh snow

Temperature

At midday at 2000 m, between +6 °C in the west and south and 0 °C in the east.

Wind

Moderate to strong northerly to northeasterly at higher altitudes and in the upper Alpine valleys in the south, elsewhere light to moderate.

Outlook

After a mostly clear night, it will be sunny on Tuesday. The zero-degree level will be between 2500 m in the west and 2000 m in the east. The wind will be moderate to strong at times on the central and eastern parts of the Main Alpine Ridge, otherwise light to moderate.

The night into Wednesday will be mostly clear. During the day it will be sunny with cumulus clouds as the day progresses and there will also be banks of cloud in the west and north. The zero-degree level will be around 2300 m. There will be a mostly light westerly to northwesterly wind.

The danger of dry avalanches will decrease on both days, but only slowly in the areas with weakly bonded old snow. The danger of wet and gliding avalanches will increase during the day. Tours and hut ascents should be completed in good time.
