Northern San Juan

You are most likely to trigger an avalanche on previously wind-affected slopes that face northeast and east. Avoid traveling near common trigger points, such as convex rollovers, rocky outcrops, or the edges of slopes where the margins of a slab are the thinnest. Give yourself a wide buffer from suspect slopes steeper than around 35 degrees. You may not experience obvious signs of instability before triggering an avalanche.

Winds will drift snow onto lee slopes throughout the day on Saturday. Small slabs of wind-drifted snow are often found adjacent to ridgelines in concave features and on the edges of gullies. Avoid steep slopes if you see cracking in recently drifted snow.
