Winds have been moderate to strong over the past few days. Combined with nearly 20 inches of new snow available for transport, these winds have formed and will continue to form slabs of wind-drifted snow on upper- and mid-elevation slopes.
These smooth, rounded pillows of wind-drifted snow rest on the Dry January weak layer. Alone, they could catch and carry a rider, but when combined with buried weak layers, they can trigger much larger avalanches.
Stick to sheltered, lower-angle terrain out of the wind. Watch for drifts, dunes, pillows, and wind-textured surfaces as these indicate recent wind loading.
Outside the wind zone: New snow instabilities remain a concern. Pay attention to lingering storm slabs and loose dry sluffs.
