Dangerous avalanche conditions exist and there is CONSIDERABLE danger on upper and mid elevation slopes with significant accumulations of heavy new snow. People are likely to trigger dangerous slab avalanches failing on a sugary buried persistent weak layer near the ground. With more accumulation overnight and more snow likely to fall today, the avalanche danger is probably higher in the Southern Bear River Range, the Logan Peak Area, and the Wellsville Range. Heavy snow and drifting from moderate west wind during today's winter storm will cause rising avalanche danger, natural avalanches are increasingly possible, and HIGH danger could develop on steep upper elevation slopes.
