    A mix of snow surfaces exist throughout the forecast region with many areas wind scoured, wind effected, with firm crusts and the occasional areas of soft snow.  Terrain that has been wind scoured down to old firm rain crusts could present fall hazards with challenging travel conditions.  Avalanche activity remains unlikely at this time.

    Practice good travel techniques when in the backcountry by having a travel plan, communicating within your group, and managing any terrain hazards.  

Avalanche Discussion

*  Observations from Tom's Valley (Jackson Meadows area) showed a variety of snow surface conditions with firm exposed rain crusts in wind scoured locations.  The upper snowpack was a combination of rain crusts and weak faceted snow with some unstable snowpack test results. 

*  A thin and weak snowpack was observed on Porcupine Ridge (Luther Pass area).  Near surface faceting was seen under small surface wind slabs.  Large surface hoar was observed between 8000 to 9400'. 

*  A relatively shallow snowpack exists throughout the forecast region.  This shallow snowpack continues to weaken and facet over time with cold temperatures and clear skies.  These weak layers could represent a problem during future loading events.
