Kootenay Boundary

As this past week's storm snow continues to settle it will still be important to evaluate the bond between the old snow surface and the new snow. There is still potential for a weak sliding layer in isolated sheltered areas.

Recent reports in the past few days indicate a few wind slabs avalanches triggered from explosives control running on the storm/old snow interface to size 2 at tree line and above.

20-40 cm of new snow from earlier in the week has buried old wind slabs, facets and surface hoar. There is a bit of uncertainty regarding how the new snow is bonding to old surfaces which formed during last week's cold clear period. Moderate to strong winds have loaded leeward features with wind slabs. A widespread crust that was buried in November is typically down 80-100cm. Recent tests show variable results with this persistent weakness. Some show results as hard and resistant and other show it may have the propensity to propagate if triggered from thin rocky areas.
