New snow continues to incrementally build over a crust. Keep an eye out for signs of instability, as you transition into open terrain in the alpine and treeline where wind slabs may linger.
New snow is being redistributed by south winds and may create fresh wind slabs in exposed lee terrain. Wind slabs from easterly winds may still be reactive.
There were a few skier triggered size 1 wind slab and dry loose avalanches reported from steep terrain on Monday.
Roughly 20 cm of new snow, with some local hot spots closer to 30 cm has been incrementally building over a crust at most elevations. Lower elevation surface snow is likely moist or wet depending on recent freezing levels.
A layer of facets (and small surface hoar in some areas) is buried 30-60 cm deep and a layer of facets sitting on a crust is buried 80-100 cm deep. While previous warming and subsequent cooling have likely helped to strengthen these layers, we will continue to monitor them for signs of reactivity.
