Avalanche Problems
No distinct problem

Field notes
SLF uses this label when no single problem dominates the assessment, often on lower-danger days. It doesn't mean conditions are safe: any avalanche type is still possible, and normal caution applies. On stable days this is usually a signal to enjoy the mountains with general awareness; on less-stable days where the assessment is still inconclusive, it's a signal to be cautious specifically because there's no clear pattern to follow.
Snowpack & Weather
Snowpack
The last few day’s new and drifted snow has stabilised well. However, this snow is lying on sometimes weakly bonded old snow. Snowpack layer in which the crystals are poorly bonded and the layer has the potential to fail. Typical crystals in dry weak layers causing avalanches are : precipitation particles; surface hoar; faceted crystals; hollow crystals; graupel. Generally >1mm in size, loose grains with few bonds Wet weak layers can be formed by all snow crystal/grain types.EAWS glossary in the Snow deposited on the ground in a multiplicity of layers.EAWS glossary are located in particular on northern and sometimes on eastern slopes above around 2400 m. On the northern flank of the Alps, they are sometimes directly beneath the new and drifted snow layers and sometimes also in the middle of the snowpack. In inneralpine regions and in northern Grisons, they are sometimes also in the lower part of the snowpack.
The Snow deposited on the ground in a multiplicity of layers.EAWS glossary has been moistened by rain below 2400 m and is saturated up to around 2100 m. Isolated Avalanche of wet snow masses. Flowing more slowly than dry avalanches; usually for shorter runout distances, however with greater impact on obstacles due to higher snow density.EAWS glossary are possible with the sunshine and rising temperatures during the daytime. Isolated gliding avalanches are still possible.

The danger of dry avalanches is decreasing, although only very slowly in areas with a persistent Snowpack layer in which the crystals are poorly bonded and the layer has the potential to fail. Typical crystals in dry weak layers causing avalanches are : precipitation particles; surface hoar; faceted crystals; hollow crystals; graupel. Generally >1mm in size, loose grains with few bonds Wet weak layers can be formed by all snow crystal/grain types.EAWS glossary problem. The danger of wet avalanches follows a daily cycle and increases slightly over the course of the day. On steep grassy slopes, isolated glide-snow avalanches are possible.
