The avalanche danger is MODERATE on drifted upper elevation slopes. Wind drifted snow has created new soft slabs up to 18" deep that may still be sensitive to a skier or rider today. Dangerous avalanches failing on a persistent weak layer near the ground remain possible on upper elevation north facing slopes.

Description
Wind drifted snow created soft and stiff slabs up to 18" deep during Wednesday's storm that will be sensitive to a skier or rider today. The wind drifts formed in exposed terrain on the lee sides of major ridges and in and around terrain features like cliff bands, scoops, gullies, and sub-ridges.
Avoid steep slopes that have a smooth, rounded appearance, or that sound hollow like a drum.

Description
Avalanches failing on persistent weak layers remain possible on upper elevation slopes with poor snow structure. Although becoming less likely with time, dangerous human triggered avalanches 1 to 3 feet deep are still possible.
  • Collapsing and cracking indicate that the snow is unstable.
