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.
