    The Dec3 interface down 60cm appears to be bonding well, but be sure to evaluate steep and committing features, particularly around treeline.

Weather Forecast

The arctic air will dominate the weather until Sunday.  The high pressure system will start to be displaced as the weekend progresses with a  low pressure system approaching from the coast. Winds will pick up at higher elevations becoming more westerly and the temperatures will slowly start to moderate into next week.

Snowpack Summary

Generally supportive and well settled snowpack above 1700m. Expect thin wind slabs in the alpine on the lee side of wind exposed terrain. The Dec 3 interface down 60cm appears to be bonding well. Snowpack continues to facet with recent cold temperatures. The base of the snowpack is weakening.
