A few more cms of new snow is likely to fall overnight and then on Tuesday another 10cm of snow is forecast to arrive with moderate SW winds at higher elevations.  Temps are once again seasonal.

Avalanche Summary

No new natural avalanche activity was observed.

Snowpack Summary

The 10-15cm of recent HST is being redistributed at higher elevations from a SW wind.  New storm slabs are building in immediate lees at higher elevations while snow in most other areas remains undisturbed by winds.  Jan 16th SH and Dec 13th CR are down 30 and 50cm and continue to produce moderate results.
