You can trigger a dangerous avalanche on wind-loaded slopes. Watch for blowing snow onto leeward aspects throughout the day Friday and avoid traveling on recently wind-loaded slopes where the snow surface has a wave-like appearance or a hard hollow feel. This slopes will primarily be on north through east to southeast aspects near and above treeline.
You can trigger a larger avalanche on most slopes facing west through north to southeast. These avalanches will break on an unusually weak layer buried about one to three feet deep. You are most likely to trigger an avalanche on this layer where the snowpack is thinner such as an uneven, rocky slope. You can find safer travel options on low-elevation slopes where you find a supportable crust underneath Tuesday's snow. If you choose to travel on steep slopes on aspects of concern pick smooth, planar slopes with no terrain traps below you.
