Although the storm has eased off, storm slabs are still likely to be encountered and could be reactive to human triggering, especially in wind loaded areas and as temperatures rise.

Avalanche Summary
Several explosives triggered avalanches to size 2 were reported in the region on Wednesday.A few size 1 explosives triggered avalanches were reported in the region on Tuesday.
Snowpack Summary
20-35 cm of new snow fell between Tuesday morning and Wednesday morning. This brings total recent snowfall amounts to approximately 40-60cm, which likely sits on a sun crust on south facing slopes and surface hoar (feathery crystals) in sheltered and shaded areas. The surface hoar is reportedly most prominent at treeline and below.Recent winds will have redistributed the new snow, forming storm slabs. Expect to find deeper deposits of snow in wind loaded terrain.
Problems
Storm Slabs
Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
