In sintesi

Small avalanches can have serious consequences in extreme terrain.

Evaluate potential travel routes for wind slabs before committing to them.

    Strong northwesterly winds are redistributing any remaining available new snow into thin wind slabs in isolated areas. Watch for wind-loaded pockets, especially just below ridgetops and in extreme and very steep terrain.

    Expect very steep south aspect terrain to become moist during days will full sun and warm temperatures.

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.
