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 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 isolated medium-to-large
sized avalanches have been triggered by persons in the last few days.
The activity of gliding avalanches continues to diminish incrementally. Nevertheless, on steep grass-covered slopes which
have not yet discharged, gliding avalanches continue to be possible in isolated cases. In the western and the northern regions
where recent snowfall has been heaviest, these releases can grow to large size in some places.
During a night of clear skies on Saturday, a melt-freeze crust which is capable of bearing loads will form on the snowpack
surface on very steep south-facing slopes.
As a consequence of daytime warming and solar radiation, the snowpack surface on steep south-facing slopes will become moist
