As new snow starts stacking up and winds continue to crank, expect the avalanche danger to rise accordingly. With heavy snowfall in the forecast, I suspect fresh wind drifts will become deeper, more widespread, and more sensitive to the weight of a rider, especially as the storm starts to materialize. Found mostly on steep, upper elevation, leeward terrain, look for and avoid any fat, rounded piece of snow, particularly if it sounds hollow like a drum.
Don't forget- shallow snowpack areas exist and there is still a chance of triggering an avalanche that breaks to old, weak snow. Steep, upper elevation, north facing slopes, especially those with a thin, weak snowpack need to be carefully evaluated or better yet, simply avoid terrain with these characteristics.
Ted Scroggin with a great photo of a cornice that fell naturally and triggered a small wind slab that left a decent pile of debris. Read the rest of his observation here. Cornices have grown quite large the past few days and may break back further than you might expect. Best to avoid being on or underneath these boxcar sized pieces of snow.
