Snow Characteristics
New Snow Depth: 
6"
New Snow Density: 
Medium
Snow Surface Conditions: 
Powder
Snow Characteristics Comments: 

About 6" new overnight, would estimate about an additional 4"+ during day.  New snow is much more wind affected than yesterday.  Below about 9,500' old snow is fairly saturated.  Freeze of old surface below new snow has increased in thickness to about 10cm and more supportable today than yesterday.  Saturated snow still remains below and boot pen is to the ground or crotch in many places.

Red Flags
Red Flags: 
Recent Avalanches
Heavy Snowfall
Wind Loading
Poor Snowpack Structure
Red Flags Comments: 
Lots of wind transport observed today, waves of high PI rates throughout day. I think the wind is playing a large factor in the hazard increasing. Observed a natural SS avalanche at 10:00 from a distance, 10,200 NE. Repeater slope, estimating 50~100' wide. 1'~2' deep ran about 500'. I would think it happened earlier in the morning sometime with increased winds loading the slope.
Avalanche Problem #1
Type: 
Wind Slab
Trend: 
Increasing Danger
Problem #1 Comments: 

Continue building with the winds and continued snowfall.  Would expect to be sensitive.  

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

Would not be surprised to have the PWL become active again with new load.  Maybe not the DDL but maybe the Valentines layer.  Could see wind slab activity initiating a P. Slab.  I am skeptical of slopes with the PWL's until I observe how they react and adjust to the new load of the next few days.  

Comments: 

Lots of wind loading/transport occurring today.
