Avalanche Summary
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 cm of new snow is now resting on a previous 20 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.
