A layer of facets over a crust is buried down 50 to 100 cm and may still be rider-triggerable on alpine slopes with inconsistent, thin-to-thick snowpack depth.
Rain and snow continue; anticipate loose wet avalanche activity at lower elevations and freshly formed storm slabs at higher elevations.
A layer of facets over a crust is buried down 50 to 100 cm and may still be rider-triggerable on alpine slopes with inconsistent, thin-to-thick snowpack depth.
Storm and wind slab formation continue at higher elevations where precipitation has fallen as snow.
Rain at lower elevations continues to saturate the upper snowpack.
There are no recent reports of avalanche activity, however, we suspect a natural avalanche cycle is ongoing with warm, and wet conditions.
Rain or wet snow has saturated the upper snowpack at lower elevations. At higher elevations recent snow has buried a variable melt-freeze crust.
In the mid-snowpack, a reactive crust/facet combination may exist in high alpine terrain.
Otherwise, the mid and lower snowpack contains a series of old crusts and is currently well-bonded and strong.
