Temperatures have cooled and we are seeing less reactivity within the snowpack. Watch for windslabs at treeline and above as well as frozen tree bombs at lower elevations.

• The number, quality, or consistency of field observations is good, and supports our confidence.

No new avalanche activity was observed.

A thin melt freeze crust was being encountered on all aspects up to 2300m and likely higher and thicker on more solar aspects. Windslabs are common at treeline and above from the strong winds over this past week with some areas stripped down to rock.

The November crust is deeply buried in the snowpack down 120-200cm. Field tests on this layer over the past few days have produced no results from a deep tap test on this layer. There is still some concern for triggering this layer from thin snowpack areas.

Cooler temperatures overnight are forecast with a low of -14C. Day time highs will climb to 5C and winds will be out NE in the moderate range. No new precip is forecast over the next few days.

• Avoid steep terrain, including convex rolls, or areas with a thin, rocky, or variable snowpack.
• Be careful as you transition into wind-affected terrain.
• Watch for areas of hard wind slab on alpine features.
