Avalanche Problem #1
Type: 
Wind Drifted Snow
Trend: 
Same
Problem #1 Comments: 

Wind slabs were my primary concern, although everything seemed to stay in place.  I tried cutting a few drifts up to 2" deep with no results this surprised me.  I felt the need to watch my slope angles and sneak off of the ridge into sheltered terrain.

Newly formed cornices were sensitive.

Considerable hazard in wind loaded areas.

Avalanche Problem #2
Type: 
Wet Snow
Trend: 
Increasing Danger
Problem #2 Comments: 

This will increase from low today to likely moderate if it warms up as forecast, more of a future hazard than today.

Elevation: 
8000
Slope Angle: 
35
Comments: 

No profile picture.  HST-8" with 14-16 sitting on the old snow surface.  ECTN in this area. 

Also, I tried some shear testing where the new snow is sitting on the crust, seemed well bonded, no shears.

Photos:

1.  This track was a trench on Friday.

2 - 4: sensitive cornices

5- Wind transport.

Overall I would say considerable hazard in wind loaded areas.  Moderate in wind sheltered areas below 8,000'.  I was able to ski 40 degree slopes in wind sheltered areas lower elevation areas..
