Recent snow and high freezing levels will create dangerous avalanche conditions.
Stick to low-angle terrain away from overhead hazard.
Expect deeper and more reactive deposits on north-facing slopes. Wind slab avalanches may step down to weak layers deeper in the snowpack and create very large avalanches.
Surface hoar and facets buried in the upper snowpack have produced recent avalanche activity. Large loads or step-down avalanches may initiate avalanches on the February layer buried deeper in the snowpack.
On Saturday, there were reports of numerous persistent slab and storm slab avalanches up to size 2.5, primarily occurring on northern aspects.
80-100 cm of recent snow has accumulated over previously wind-affected surfaces and crusts on steep south-facing terrain.
Three layers of concern currently exist in the upper-mid snowpack. Surface hoar that formed in mid-March can be found 65 to 100 cm below the snow surface. Below this, another layer of surface hoar that formed in early March can be found at a depth of 100 to 150 cm. Additionally, a layer of facets, surface hoar, and/or a crust from mid-February is buried 100 to 200 cm deep.
The remainder of the snowpack is well consolidated, and there are no current concerns.
