Persistent Slab: Small-large possible on NW-E
More snow and westerly winds are pushing the snowpack towards a tipping point. Wind-drifted slabs building on easterly-facing slopes below ridges or the backside of steep rollovers are the most dangerous and likely places to trigger an avalanche. Look for shooting cracks along the snow surface or booming collapses as clear signs of this problem. Wind-drifted snow will often appear smooth or rounded and feel denser than the snow in protected terrain. With growing slabs and weak snow below, any avalanche you trigger may break wider and deeper than you would expect.
