Highlights

Touchy storm slabs reactive to human triggers. Use small slopes with low consequence to test the bond of the storm snow.

    Touchy storm slabs reactive to human triggers. Storm slab reactivity may persist for longer than usual due to the presence of buried surface hoar (feathery crystals) or hard crusts.

Avalanche Summary

On Saturday, numerous skier triggered avalanches up to size to 2 were reported near Whistler.

Snowpack Summary

50-90 cm of recent storm snow has buried a wide variety of old snow surfaces including stiff wind slab or wind effected snow at upper elevations, sun crust on steep southerly slopes, surface hoar and surface facets in sheltered locations. The mid-January interface (facets) is buried approximately 100-180 cm down. The mid and lower snowpack is generally well settled (strong). However, there remain a number of facet and crust layers that are currently dormant but will require monitoring with additional loading.
