    Strong northwesterly winds are redistributing new snow into thin wind slabs in isolated areas. Watch for wind-loaded pockets, especially around ridgecrest and in extreme terrain.

Terrain and Travel Advice

  • If you are increasing your exposure to avalanche terrain, do it gradually as you gather information.
  • Carefully evaluate steep lines for wind slabs.
  • A crust on the surface will help bind the snow together, but may make for tough travel conditions.
