Expect quiet, but dangerous avalanche conditions with fragile weak snow lurking two to four feet below the surface. You may not get any collapsing or cracking before triggering a large, deep avalanche. You might trigger one of these avalanches from below a slope or from a distance so avoid traveling both on and underneath steep slopes facing west through north to southeast. Look for safer options on south and southwest-facing slopes where the early season snow melted, or by avoiding travel on or underneath slopes steeper than about 30 degrees.
Friday's new snow will obscure areas of recently wind-drifted snow that formed on easterly-facing terrain on Thursday. In recently drifted areas, an avalanche might break a foot or two deep, then break to near the ground once in motion.
