Red Flags Comments: 
Noticed a couple natural soft wind slab avalanches that occurred today, while we were in the area. These were both around 1' deep and 50' wide, and on drifted east facing slopes at around 9300' in elevation. The avalanches were not very desrtuctive and didn't run especially far. They looked like they were triggered by cornice fall, and occurred durring periods of heavy snowfall and fairly strong winds.
Avalanche Problem #1
Type: 
Wind Slab
Trend: 
Increasing Danger
Problem #1 Comments: 

Wind slabs were pretty soft and non-threatening, especially since we avoided drifted slopes.  But natural avalanches were occurring, so obviously a factor.  Tomorrow's wind slabs in exposed lee terrain could be stiffer, thicker, wider, run farther, and be less manageable than they were today.
