Avalanche Problem #1
Type: 
Persistent Slab
Trend: 
Same
Problem #1 Comments: 
This Monday's storm snow sits on top of storm snow and wind slab from last Thursday's strong frontal passage. These snow layers sit on top of near surface facets on W-N-E facing slopes at mid and high elevations. Extended Column Tests showed propagation with medium friction on this NSF layer where wind had consolidated a slab above. In shallow snowpack areas the rest of the full depth of the snowpack is very sugary faceted snow which a slab failure in the upper snowpack could easily gouge down through to the ground likely entraining a great deal of snow. Other snow layer interfaces with weak, faceted snow are also possible in locations more prone to wind deposition and slab formation.
Avalanche Problem #2
Type: 
Loose Wet Snow
Problem #2 Comments: 
Warm temperatures, clear skies and pounding sun are affecting a wider and wider swath of cold winter snow each day. Daytime heating of the solar half of the compass, at all elevations may produce natural wet activity.
