Be cautious in areas that look wind loaded, pillowed, or extra thick.

Continued snow and wind have made wind slabs in the alpine and treeline.

Avalanche Summary

On Monday, a remote and a rider triggered avalanche were reported in the Quesnel area, both were size 2 and were new snow sliding on facets.

On Sunday, a small (size 1) storm slab avalanche was reported around the Barkerville area. There was another report of a small (size 1) reactive storm slab avalanche around Wells on Saturday.

Snowpack Summary

10-20 cm of new snow is now resting on a previous 10 cm that was redistributed by strong northeast wind. This upper 30 cm of recent snow may bond poorly to underlying layers of surface hoar, faceted snow, and wind-pressed snow.

A thin breakable crust has been reported on the surface at lower elevations in the Sugarbowl area.

A prominent crust is found 30 to 50 cm deep. It extends up to 1900 m in the Cariboos and up to 1400 m around Pine Pass. In the Sugarbowl and Quesnel / Williams Lake areas, a layer of small surface hoar or facets has been observed near the crust.

The midpack is reportedly strong and bonded.
