Southern San Juan

You might be able to trigger a slab avalanche on steep, shady slopes at upper elevations where the snowpack remains cold and dry. Avoid steep, rocky slopes above treeline where the snowpack is shallower and trigger points, like convexities and shallowly-buried rocks, are more abundant.

Safer travel can be found on sunny slopes with supportive crusts early in the day, but head for the shade if you start to sink into wet, mushy snow or if it collapses underneath you. Friday night looks a bit warmer than previous nights, so conditions may deteriorate faster than anticipated.
