Heavy Snowfall
Wind Loading
Avalanche Problem #1
Type: 
New Snow
Trend: 
Increasing Danger
Problem #1 Comments: 
Accumulating snow created soft slab conditions with potential for entrainment of skier. Cornices fairly sensitive for release. We dropped a small cornice on ~30 degree slope and triggered a soft slab which ran ~300 vertical feet.
Avalanche Problem #2
Type: 
Deep Slab
Trend: 
Increasing Danger
Problem #2 Comments: 
Wind slab formation on leeward slopes. Because of variability in wind direction, predicting where wind slabs may have formed below ridges could become more difficult.
