    Loose snow will continue to be a problem in steep rocky areas and gullies until the facets round out a bit.

Weather Forecast

The chinook winds showed up on Saturday and may be expected to build windslabs in immediate lee areas near ridgecrests. New snow and continuing wind over the next few days will likely add to the problem.

Snowpack Summary

20-50cm of snow sits over the december 15 surface hoar layer which is beginning to develop some slab properties. Below this the snowpack is heavily faceted with remnants of older crust's still lingering throughout. In many areas loose faceted surface snow continues to be the main instability of the snowpack.
