Snow Characteristics
Snow Surface Conditions: 
Powder
Faceted Loose
Wind Crust
Melt-Freeze Crust
Snow Characteristics Comments: 

Quite a wide variety of snow conditions out there.  Everything from wind hammered and unsupportable crusts to some nice settled old powder, to loose skiable facets.  Did not observe the SH that has been being talked about.  The areas where it existed yesterday seemed to have been destroyed by the wind or possibly even the temps.  I would suspect that it remains in a few isolated areas that are protected enough from the wind.

Red Flags
Red Flags: 
Wind Loading
Cracking
Poor Snowpack Structure
Avalanche Problem #1
Type: 
Wind Drifted Snow
Trend: 
Increasing Danger
Problem #1 Comments: 

Saw some wind slabs that had formed since the winds cranked up with what little snow is left around available for transport.  Sensitive, yet shallow in specific areas.  Would suspect that this will become more of an issue with the new snow.

Avalanche Problem #2
Type: 
Persistent Weak Layer
Problem #2 Comments: 

If we actually get some snow out of this storm I would expect things to go off with the weak top to bottom snow pack that seems to exist pretty much anywhere there is snow.  I would expect them to go full depth once initiated, dependent on the new load.  Souths are bare in most places.

Comments: 

Large, striated cupped depth hoar on the ground at 10,400' N

Faceted graupel mid pack
