Avalanche Summary

No new slab avalanches were reported in the region.

Snowpack Summary

Expect to find 20 to 40 cm of settling snow in sheltered areas, and wind slabs on lee slopes. On sun-affected slopes, the soft snow covers a melt-freeze crust.

A layer of surface hoar, crust and/or facets exists 60 to 110 cm deep. Reports indicate this layer is hard to find and likely not a concern north of Highway 5. South of Highway 5 it may linger on north through east aspects between 1700 to 2300 m.

Snow depth at treeline is 120 to 150 cm.
