Travel and Terrain Advice
Be on the lookout for storm slabs that have formed due to snowfall since yesterday. The danger is even greater in areas where slabs are forming while under the influence of northwest winds. Carefully check the bonding strength of the interface between the new and old snow. The rate of improvement in instability depends on elevation, aspect, and slope characteristics. Starting the day on a slope that is simple, small, and free of terrain traps is a good idea. The weather is improving, but continue to make careful terrain decisions until you descend to the base. Keep to the principle behaviors of stopping in a safe areas, skiing one at a time, and spacing out.
