Points saillants

New snow may not bond well to the old.

If you see more than 10 cm of snow, treat the danger as one level higher and reduce your exposure to avalanche terrain.

Avalanche Summary

No new avalanches have been reported since Wednesday.

Snowpack Summary

Treeline snow depths are typically 50 to 80 cm, with deeper wind-loaded pockets in the alpine. Heavily wind-affected surfaces are being reported in exposed terrain. A new sun crust is reported to be forming on steep, sun-exposed slopes.

There is a melt-freeze crust near the base of the snowpack, but it generally appears to be stable and is not currently expected to be a problem for the region.
