Primary Problem: New Snow
Bottom Line: New snow will create the main avalanche hazards this weekend. Avalanches could show a wide range of characteristics, from slabs of wind-drifted snow to wet-loose avalanches that run long distances. Where more snow falls, slab avalanches could break within or below the new snow, even where not drifted. Wet snow avalanches breaking deeper than the new snow are possible on slopes that have wet, unfrozen snow below the new snow, or where a lot of precipitation falls as rain on a wet and unsupportable snowpack. If you travel on or below steep slopes, carefully assess the new snow for signs of instability. Continuously reassess snow stability throughout the day, and as you move through different aspects and elevations.

  • Ian in front of the Sawtelle weather station

    Went to do maintenance on the Sawtelle Snowfall weather station at 8800 ft just off the Sawtelle Mountain Road. Continuous snowcover starts around 8000 ft. At 8800 ft there is ~20" of snow with a mix of hard crusts and weak facets. These weak layers near the ground will be something to watch once snows again. Photo: GNFAC

  • Avalanches at Pine Creek

    From IG: “Pine creek today, some small wind slabs and a full depth wet slide off black mountain”
