Observation Date:

Observer Name: 
B
Location Name or Route: 
Mary Ellen Gulch
Weather
Sky: 
Overcast
Wind Direction: 
Southwest
Wind Speed: 
Moderate
Weather Comments: 
Early morning mostly clear skies gave way to overcast and thick cloud cover by mid day. Tempertures rose rapidly during the hours of direct solar, and then back off and descended in the afternoon at upper elevations. Winds were strong on the upper ridgelines and moderate in the more protected upper bowls. Transport and or wind blown was strong in the most exposed areas just off the ridgelines.
Snow Characteristics
Snow Surface Conditions: 
Dense Loose
Faceted Loose
Wind Crust
Melt-Freeze Crust
Rain-Rime Crust
Snow Characteristics Comments: 

The snow surface conditions continue to degrade and become more variable every day. And as a result the riding conditions become more challenging. Dense settled powder was able to be found in isolated places, but runs of consistent friendly turning conditions were difficult to find in the upper and mid elevation exposed terrain of Mary Ellen. Of note, the conditions appeared to be improving as they began to soften around 1100 hours, but once the cloud cover moved in things changed for the worse as the snow surface began to refreeze. 

Red Flags
Red Flags: 
Wind Loading
Poor Snowpack Structure
Avalanche Problem #1
Type: 
Persistent Weak Layer
Trend: 
Same
Problem #1 Comments: 

No red flags observed besides the wind loading, but as described above, the structure is suspect, and confidence remains low for safely attacking steep shady aspects

Avalanche Problem #2
Type: 
Wind Drifted Snow
Trend: 
Increasing Danger
Problem #2 Comments: 

See above, and it appears that these westerly and southwesterly winds are not abating at 2100 hours. As a result, this hazard may continue to increase tonight and into Wednesday in the previously cited upper elevation terrain. 

Danger continues to be a low probability/high consequence Moderate in the persistent slab regions, NW, N, NE, and E.
