In the lower part of the snowpack, particularly on west-facing, north-facing and east-facing slopes above approximately 2200 m, weak layers are evident. In the western Lower Valais and on the northern flank of the Alps these ground-level layers are covered over by thick layers of fresher snow so that the likelihood of avalanches being triggered by persons is low. From central Valais over the Ticino as far as Grisons, the snowpack layering is least favourable. In those regions, there have been medium-sized avalanches triggered by persons during the last few days.
Gliding avalanches can still trigger on steep grass-covered slopes which have not yet discharged in isolated cases.
On shady slopes the upper part of the snow cover is expansively metamorphosed (faceted) and loose in many areas, in some places there is surface hoar blanketing the surface. On steep south-facing slopes a melt-freeze crust forms during the nocturnal hours which is capable of bearing loads.

Following a night of clear skies it was sunny in the mountains during the daytime.

-

At midday at 2000 m, between +2 °C in the western regions and -1°C in the southern and the eastern regions.

Winds during the nighttime hours were blowing at moderate strength, from place to place at strong velocity, from westerly directions; during the daytime, winds were light.

Skies will be partly cloudy during the night, during the daytime it will be quite sunny in spite of cloudbanks.

-

At midday at 2000 m, between +4 °C in the western regions and +1 °C in the southern and the eastern regions.

Winds will be blowing at moderate strength, in some regions at strong velocity at high altitudes, from westerly directions.
