South Coast

Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.

When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.

Numerous rider triggered size 1 wind slab avalanches were reported on northerly aspects in the alpine around the Sky Pilot zone on Thursday.

If you head out in the backcountry, let us know what you are seeing by submitting a report to the Mountain Information Network.

10-20 cm of new snow Thursday night and light southwest wind.

Below the recent snow is a melt-freeze crust, existing on all aspects at treeline and below. The crust extends to mountain tops on sunny aspects. In north facing high alpine terrain the surface snow may have remained cold and dry.

The mid and lower snowpack are generally well settled and strong.

• Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
• Carefully evaluate steep lines for wind slabs.
• Avoid exposure to slopes that have cornices overhead.
• When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
