Verify conditions as you gain elevation.
Wind slabs are possible where precipitation falls as snow, wet loose avalanches are possible where precipitation falls as rain.
New, rider triggerable wind slabs will likely form on specific features at treeline and above.
Strong wind means that wind slabs could be found further down slope than expected.
Wet loose avalanches are possible in steep terrain at low elevations where rain falls on dry snow.
Several size 1 to 2 natural wind slab avalanches were observed on Wednesday. These avalanches occurred in steep terrain and may have been triggered by cornice failures.
No avalanches were reported on Thursday, but observations in the region are limited.
The snow surface is highly wind-affected in exposed terrain, in sheltered terrain up to 35 cm of soft snow can be found. Below 1300 m, a crust is present just below the surface.
A layer of facets is buried around 50 to 100 cm deep and is slowly gaining strength.
The mid and lower snowpack have no layers of concern. Snowpack depths are generally around 150-200 cm deep at treeline.
