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 elevations where rain falls on dry snow.
On Friday, 1 size 1 skier triggered avalanche was reported, this avalanche occurred at treeline on a steep slope. Check out the MIN report for more details.
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.
The snow surface is highly wind-affected in exposed alpine terrain, in sheltered terrain at treeline up to 40 cm of soft snow can be found. Below 1300 m, a crust is present just below the surface. As the rain line creeps up the snow surface will become moist at treeline and below.
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.
