Primary Problem: Wind Slab
Bottom Line: Avalanche problems will involve recent new snow. Otherwise, the snowpack is generally stable and larger avalanches are unlikely. Be on the lookout for fresh drifts and avoid them, especially in consequential terrain. Monitor the snow surface for wet snow avalanche potential. If the new snow is becoming moist find lower angle terrain or shadier slopes with drier snow. Consider the consequences of being knocked over by a small slide. Daily forecasts are done for the season, but avalanches will continue. Remain diligent with your snowpack and terrain assessments, and be ready to adapt your plans to changing conditions.
