    Recent and forecasted snow will be moved around by the SW winds and forming fresh wind slabs in the alpine. These slabs can fail on the the Dec 15 interface which is showing easy to moderate shears.

Weather Forecast

Cooling trend with up to 10 cm new snow at tree-line and moderate SW winds forecasted for Wednesday. High pressure ridge will start to rebuild over area on Friday.

Snowpack Summary

25-40cm of snow sits over the Dec 15 layer which consists of surface hoar, sun crust, or facets depending on location. Easy to mod shears found on this layer. Below this the snowpack is heavily faceted with remnants of older crust's still lingering throughout, but no significant shears found in the lower pack. Some isolated windslabs near ridgetop.

No natural avalanches observed or reported in past 24 hours.
