Precipitation: 
Light Snowfall
Wind Direction: 
Southwest
Wind Speed: 
Moderate
Weather Comments: 
Overcast throughout the day with S minus 1 snowfall after 1700. Winds were moderate out of the SW and only observed in the alpine. Wind blown and or tranport was moderate on the exposed ridgelines. Temperatures warmed into the mid to upper 20's at and above 8700 feet.
Snow Characteristics
Snow Surface Conditions: 
Dense Loose
Wind Crust
Snow Characteristics Comments: 

Winds from overnight damaged much of the upper elevation exposed terrain. Scouring and dense slabs were observed. Soft 4 finger slabs up to 9 inches thick as well as hard slabs that were knife hard and 4 inches thick were scattered in the alpine. Patches of dense wind slab were intermixed with dense creamy snow in the alpine. There were still good turning conditions in somewhat dense settled powder down off the ridges and especially in the more protected areas. 

Red Flags
Red Flags: 
Recent Avalanches
Wind Loading
Cracking
Poor Snowpack Structure
Red Flags Comments: 
Reports of avalanches in the outlying terrain outside of the Alta and Brighton perimeter where the shallow snowpack concerns exist continue to be reported. Overnight winds were obviously loading leaward terrain features throughout the day, and these winds had actually died down from the sustained overnight velocities. Cracking was observed on steep terrain features that had loading as described above.
Avalanche Problem #1
Type: 
Wind Slab
Trend: 
Same
Problem #1 Comments: 

The winds overnight on Monday appear to be forecast to be in critical speeds and continued loading may be occurring with the potential to overload areas that are housing shallow snowpack/poor structure. The danger appears to be maintaining the same trend of sustained danger. 

Avalanche Problem #2
Type: 
Persistent Slab
Trend: 
Increasing Danger
Problem #2 Comments: 

Persistent slab concerns as cited above appear to be likely in areas that have a shallow snow pack and are receiving substantial loading from the SW and S winds. N, NE, E and SE aspects remain suspect in these specific isolated areas. 

Reports from Mineral Basin and the Brighton Perimeter were noting mostly stable conditions with isolated pockets of wind slab potential with no naturals observed. As a result, moderate appeared to be the danger rating in these areas. Sustained winds overnight and into tomorrow may escalate the danger to considerable.
