Kernpunkte

Finally some new snow! But use caution during your travels, as it may not bond well to the underlying wind-affected snow. It will fall with strong northwest wind, so use particular caution in lee terrain features.

Snowpack Summary

New snow on Tuesday will fall onto a heavily wind-affected snow surface. The new snow may form touchy wind slabs quickly, as the storm will have associated strong northwest wind. Beneath the new snow lies a variety of hard slabs, wind-pressed snow, sastrugi, and melt-freeze crust. In sheltered areas at and below treeline, the new snow will fall onto pockets of feathery surface hoar crystals and soft faceted snow. In the south of the region, the remainder of the snowpack is well-settled.Around Bear Pass and in the north of the region, you may find two or three weak layers of surface hoar buried between 50 and 100 cm. The base of the snowpack may also be composed of weak and sugary faceted snow.
