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 snow line on northern slopes is at 1800 m and around 400 m higher on southern slopes. At high altitudes, there are patches of continuous Snow deposited on the ground in a multiplicity of layers.EAWS glossary in Usually a steep, elongated, eroded trench; typically prone to snowdrift accumulation.EAWS glossary and Rounded or elongated concavity; typically tending to accumulate snowdrift.EAWS glossary on shady slopes. The snow is significantly deeper above 2800 m.
In particular on north-facing slopes above approximately 2800 m and generally in the Areas above approximately 3000 m (particularly glaciated areas).EAWS glossary, near-ground layers have become faceted. As demonstrated by avalanches triggered on Sunday, in these regions avalanches can start in the Snow layers deposited from earlier precipitation, prior to fresh fallen snow. Old snow layers consist of metamorphosed snow crystals.EAWS glossary and sometimes become large.
Outlook
Conditions will be mostly sunny in the mountains on Thursday and Friday. Temperatures will remain very mild with a zero-degree level above 3000 m and the southwesterly wind will be light to moderate.
Avalanche risk will decrease.
