Primary Problem: Wet Snow
Bottom Line: Avalanche concerns through this weekend will chiefly be driven by the new snow that fell this week, in combination with warm temperatures and sunshine. Avalanches could break in the recent snow, particularly on shady, high elevation slopes. On sunny slopes, the new snow provides the needed ammunition for big wet loose sluffs. Recent slides also remind us that it’s still possible for avalanches to break deeper.

  • 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
