Weak layers remain sensitive to human triggering, producing large avalanches.
Avoid exposure to large, open slopes - including overhead hazard.
Wind slabs likely remain reactive. Be especially cautious if you observe active wind transport of snow. Wind slabs may step down to deeper persistent weak layers, producing very large avalanches.
Large avalanches on this layer continue. It is most triggerable in areas where the snowpack thins (steep, rocky slopes).
On Saturday explosive, natural and remotely triggered avalanches continued, producing size 2 to 3 avalanches. Several triggered as wind slabs on steep slopes, before stepping down to the December crust/facets/surface hoar. Activity was concentrated on northwest through east face slopes at treeline and above.
Natural activity will likely continue to decrease, but the snowpack is expected to remain primed for human triggering.
Light snowfall will bury a layer of surface hoar in sheltered areas. Previous storm accumulations of up to 80 cm were heavily wind affected by west/southwest winds in exposed areas.
A layer of surface hoar, facets, or a thin crust is buried 30 to 60 cm deep at upper elevations.
Buried 100 to 200 cm deep is the current layer of concern - surface hoar, facets, and a crust. This layer produced large natural avalanches during the recent storm and continues to be very reactive to triggers.
