6:15 AM update: Expect danger to increase through the day as the new snow accumulates.
Make conservative choices and avoid avalanche terrain.
Storm slabs continue to build throughout the day. The new snow falls on a variety of surfaces, carefully assess the bond as you travel. The new snow arrives with significant wind, expect deposits to be deeper on north aspects.
On Tuesday, there were reports of skier triggered wind slabs up to size 1 in steep NE terrain. Sluffing was reported to run fast and far on sheltered north aspects.
New snow is falling on a variety of surfaces, including wind-affected snow in the alpine, facets on north aspects, and sun-affected snow on the south aspects. Expect the potential for a poor bond to form in areas where facets or crusts exist.
There is a crust from early February that is down 20 to 60 cm and seems to be well bonded to the new snow.
The remainder of the snowpack is well-bonded.
The snowpack depth at treeline ranges from 90 to 170 cm. The snowpack depth tapers rapidly below treeline, especially on south aspects.
