You can trigger an avalanche on slopes where you find more than eight inches of drifted snow. Southeast winds formed the deepest drifts on northerly and westerly-facing slopes. You are more likely to trigger an avalanche on slopes steeper than about 35 degrees that are near ridges, on rollovers, or along gullies. Avoid traveling across steep slopes with smooth and pillow-like snow, and adjust your travels if you see cracking in the snow. Wind-scoured slopes and low-elevation terrain offer generally safer conditions.
Warm temperatures, light wind, and ample sunshine will warm the snow surface on sunny and low-elevation slopes. Avoid traveling on or below steep slopes with rollerballs, pinwheels, and wet, gloppy snow. The threat of wet avalanches will increase during the day.
