South Coast

Wind slabs will be reactive to human triggering at upper elevations.

Friday, riders were able to trigger storm slabs up to size 1.5 on steep features.

Looking ahead, we expect rider-triggered avalanches to be possible, especially in areas with reactive wind slab deposits.

Thank you for your continued posting to the Mountain Information Network (MIN).

20 to 30 cm of storm snow that came with moderate to strong south winds is rapidly settling at upper elevations. Expect windward slopes to be scoured. Lower elevations have received rain.

This snow overlies a thin, breakable rain crust. Below, another 30 to 50 cm of previous snow, also well-settled and reportedly well-bonded to the old snow surface exists. The lower pack is also well-settled melt forms or moist snow.

Snow depth is between 125 cm and 250 cm at treeline.

At lower elevations, expect early-season hazards and a thin, rain-saturated snowpack, with a crust or moist snow at the surface.

• Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
• Choose low-angled, sheltered terrain where new snow hasn't been wind-affected.
