A dangerous "strong-over-weak" structure persists, with old, weak snow buried near the ground. Rain reaching the highest elevations is adding significant stress to the snowpack, creating stubborn slabs over moist, faceted snow.
These avalanches will be the largest on upper-elevation slopes where recent southerly winds previously drifted additional snow onto the terrain. However, the snowpack may be more sensitive further down, where the slabs are thinner and the underlying facets are moist.
