Wind slabs remain possible to human trigger.
Continually assess as you travel. If the snow looks wind-affected or feels dense or stiff, back off.
Dry snow at upper elevations is being redistributed by moderate to strong winds. New wind slabs are likely developing over a previous surface of hard wind pressed snow and/or a crust.
A buried layer of facets in the snowpack is expected to be more reactive in wind-affected thin rocky terrain features. Triggering of this layer is less likely where a supportive crust is present.
On Saturday, a very large natural wind slab avalanche was reported that occurred during the storm.
New low density snow is incrementally accumulating and being redistributed by moderate southwest wind over a mix of moist or refrozen recent storm snow.
At upper elevations heavily wind affected surfaces can be found. Hard wind slab, and wind pressed snow with new small wind slabs forming are likely.
Below this, a layer of facets from early February is roughly 50 cm deep, and a thick crust from late January up to 100 cm deep. These layers are less likely to be triggered where a supportive crust is present.
