New snow accompanied by southerly wind may form small rider triggerable wind slabs.
Carefully assess and verify conditions. Observations in this region have been limited and we are uncertain of reactivity of weak layers in the mid and lower snowpack.
New snow accompanied by southerly wind may form small rider triggerable wind slabs.
Buried surface hoar is likely becoming harder to trigger, however, consequences remain high if triggered.
No significant avalanches have been reported in the region in the past few days.
If you are out in the backcountry please consider filling out a MIN report.
Up to 15 cm of recent snow has likely formed wind slabs at upper elevations. A variety of surfaces are found below this new snow including surface hoar in sheltered terrain and a crust below 1600 m.
The mid-pack contains various noteworthy layers; including two surface hoar layers, one down roughly 20 to 40 cm and another down roughly 60 to 90 cm. Between the two surface hoar layers a crust may exist, primarily at lower elevations.
The current snowpack has considerable variation in structure and depths across the region but is generally facetted and weak.
