Three to six inches of snow with consistent, strong westerly wind created dangerous avalanche conditions near and above treeline. You can easily trigger an avalanche on most steep, wind-loaded slopes and some of these avalanches might occur naturally as the wind transports additional snow onto the lee sides of ridgelines. Identify and avoid wind-loaded slopes to reduce your chances of triggering an avalanche. You can identify wind-loaded slopes by their smooth, rounded, often-wave-like appearance and the hard, hollow feeling you will experience when traveling across them.
You can also trigger a smaller loose avalanche on slopes generally steeper than around 40 degrees on wind-sheltered slopes below treeline. You can find safer travel options by sticking to wind-sheltered terrain below the treeline and avoiding slopes with terrain traps such as a cliff or a gully below you where even a small loose avalanche could seriously injure or bury you.
