{"blocks":[{"key":"3huoa","text":"Saturday's powerful storm brought 40-70 cm of snow to the mountains. Gradual warming that peaked midday likely created a thin crust over much of the storm snow in areas below 1100 m. Strong south winds redistributed the new snow into dense slabs that may remain possible to trigger, especially where slabs are poorly bonded to the previous surface. The recent snow sits on a mix of previous surfaces, including preserved powder, a sun-crust on steep south-facing slopes, and surface hoar reported at treeline elevations and below. Stay alert to changing slab conditions as you move into wind-exposed terrain, and monitor the bond of the new snow to the old snow surface.

This video, filmed prior to Saturday's storm, provides a valuable visual summary of these conditions. It may be possible to human trigger this persistent slab problem in thinner snowpack areas near ridge tops, where the facets are more developed and where the crust layers are more accessible to the weight of a person or machine. Backcountry travelers near Mt Mulligan on Saturday found this layer down 100 cm after experiencing a whumph. You can find additional details and photos about this persistent slab problem in our forecaster blog.
