Down roughly 80-150 cm from the surface a weak layer of faceted snow and spotty surface hoar may persist atop a firm crust.
With freezing levels gradually decreasing natural avalanche activity will likely also decrease. Human-triggered avalanches remain possible.
Down roughly 80-150 cm from the surface a weak layer of faceted snow and spotty surface hoar may persist atop a firm crust.
Expect wet loose avalanche activity to persist, especially late in the day due to warming temperatures and solar effect.
These may step down to deeper layers resulting in larger-than-expected avalanches.
Observations over the weekend were limited, however, we suspect recent widespread wet loose and wet slab avalanche activity.
As sunny days and high freezing levels continue, more of the upper snowpack will get moist or wet. The snowpack remains generally unstable.
80 to 120 cm below the snow surface, a weak layer of faceted snow may exist sitting atop a crust on all but high north aspects.
The mid and lower snowpack is generally settled and strong.
