Snowpack Summary

Up to 15 cm recent snow covers a crust on all aspects except high north terrain. Wind has impact snow at upper elevations, as it shifts east new wind slabs may reverse load features. The mid and lower snowpack is well settled and bonded.

Terrain and Travel

  • Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
