Avalanche Summary
A small amount of new snow doesn't change the danger, but gusty winds mean that any available snow drifted into thin slabs above treeline. Leeward ridgelines and cross-loaded terrain features on east and northeast-facing slopes are the most likely to harbor firm, drifted snow. If you were to trigger an avalanche in a patch of wind-drifted snow, it would be small.
