Avalanche Summary

No new avalanches have been reported in this region.

Snowpack Summary

10cm of new snow is being redistributed by moderate southerly ridgetop winds. The reactivity of the new storm slabs is likely to vary greatly depending on elevation/ temperature and orientation to wind. In general, I would expect the touchiest conditions to exist in exposed, higher elevation terrain.
