Strong westerly winds are drifting snow onto easterly-facing slopes. Avoid steep slopes with drifted snow even if you don't see shooting cracks or other signs of instability. An avalanche in drifted snow can step down to deeper layers in the snowpack creating a large and dangerous avalanche.
You can find safer conditions on sheltered slopes at lower elevations. Change your plans if you find more than about 8 inches of new snow and you experience shooting cracks.
