You can trigger an avalanche on slopes with around 8 inches or more of drifted snow. Recent southeast winds built the deepest drifts are on northerly and westerly-facing slopes and avalanches on those slopes will be larger. You are more likely to trigger an avalanche near ridges, on steep rollovers, and in cross-loaded gullies around 35 degrees in steepness or more. Avoid traveling where the snow surface looks smooth and pillow-like, 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 elevations 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.
