    The hard windslabs that dominate the alpine snowpack have been unreactive lately.  It still may be possible to trigger an avalanche on steep unsupported terrain from thin areas and edges of these slabs. 

Weather Forecast

A few flurries are possible into the weekend, however they will only provide a trace of accumulation.  Temperatures will remain mild for this time of year with increasing influence from solar radiation in the afternoon.  Winds will be light from the SW.

Snowpack Summary

Hard windslab is bridging the weak basal facets on most lee aspects above treeline.  The treeline mid-pack continues to weaken as the faceting process continues and below treeline the snowpack is thin and weak.

Avalanche Summary

No avalanche patrols were conducted today.

Confidence

The weather pattern is stable
