Continually assess the snowpack for signs of instability with dynamic weather conditions.
Human triggering of deep persistent weak layers remains possible, especially in shallow areas with variable snow depths. Consequences could be severe if triggered.
No recent avalanches have been reported in the region.
Please continue to share any observations or photos on the Mountain Information Network.
High freezing levels produced moist surface snow up to 2000 m on Friday. As temperatures cool a crust will form.
At alpine elevations, roughly 10 cm of low-density snow since the weekend overlies a generally well-settled upper snowpack. The mid and lower snowpack consists of loose facets, with a significant weak layer of large facets and a crust down 80 to 120 cm from the surface. The snow below the crust is generally weak and unconsolidated.
Treeline snow depths are roughly 140 to 160 cm.
