Weather Comments
Winds were very light, even along exposed ridgelines. Only snow transport that I noticed was very minimal, and on a very exposed ridge at 10,600'. Temps stayed in the mid 20's most the day. Did notice a very brief period of greenhousing around 2pm, but seemed very localized and minor.

Snow Characteristics Comments

11" at 9,000' with 0.75" of water. Closer to 14" above 9,000.' Snow fell with nearly no wind and was right side up and blower. 

Red Flags
Red Flags Comments
No real red flags. Because the snow fell with very little wind and was so light density, there just wasn't enough of a slab. The old snow surface was consolidated and locked up from the warm temperatures early in the day.
Avalanche Problem #1
Type
Loose Dry Snow
Problem #1 Comments

Only activity observed was sluffing of the new snow in steep terrain. Sluffs moved slow and were very manageable. They could be a bit larger tomorrow with additional light density snow.

Comments

Photo is of dry loose activity in steep N facing.

Hazard tomorrow depends entirely on how much snow overnight and whether winds stay calm or not. If things continue as forecast anticipate at mostly moderate hazard, with pockets of considerable on the highest peaks. If winds bump up or we get a lot more snowfall, may be a more widespread considerable.
