Light winds and a few inches of snow aren't enough to increase the danger. You can trigger an avalanche in drifted snow below steep ridgelines and convex rollovers. Look out for problematic drifts on alpine slopes that face northeast through east to southeast. Intense winds drifted snow into dense slabs on some slopes but completely scoured others. Right now, many of the most enticing places to ride are where you find problematic drifts. Hollow-sounding snow or cracking in the snow are signs to avoid steep slopes. Although, you probably won't see any warning signs before you trigger an avalanche.
On shady and sheltered slopes at lower elevations, the snow is cohesionless and can sluff off of very steep slopes. These can be dangerous if you're above a gully or cliff.
