Avalanche Summary

Explosive control produced small (size 1) slab avalanches on Tuesday. No other avalanches were reported.

Snowpack Summary

Relatively light amounts of moist snow have fallen on a variety of snow surfaces including a crust on steep southerly slopes and possibly weak surface hoar crystals on sheltered and shaded slopes. The new snow may take a little time to bond, especially on northerly aspects at higher elevations.A layer of weak and sugary faceted grains sits on a melt-freeze crust about 50 to 120 cm deep. The layer is likely most prominent in the North Shore Mountains and on north aspects. This layer continues to be reactive in snowpack tests. The problem is not typical for the region and we expect this persistent weak layer to continue to linger.The lower snowpack is generally strong.

Problems

Wind Slabs

Thin wind slabs may develop on the downwind side of ridges as light amounts of new snow fall on this region.

Use caution in lee (downwind) areas.

Aspects: North, North East, East.
