    Wind slabs may form as new snow and strong wind impact the region. Expect to find them in wind-loaded terrain near ridges. Also assess how new snow is bonding to previous surfaces.

Avalanche Summary

We haven't received reports of avalanche activity over the past few days. We expect that new wind slabs may form, which riders could trigger on Tuesday.

Snowpack Summary

New snow and strong southerly wind are forecast, which may form new wind slabs near ridges. Storm slabs may begin to form in areas sheltered from the wind.

Snow depths at White Pass are around 100 cm in sheltered areas and 200 cm on wind-loaded slopes.
