    Within the past week, there have been occasional reports of skier remote and explosive triggered slabs on the Oct 26 crust and facet layer. Avoid steep terrain where a stiffer, more cohesive slab exists over the weak snow at the base of the snowpack.

Weather Forecast

Thurs-Friday will be a mixed bag of  sun/cloud and we may see occasional flurries (up to 5 cm). Cold air pushes into the region Friday night as the winds switch to NW and temperatures drop to -15 to -20 .

Snowpack Summary

The October 26 crust is found ~10-30 cm above the ground. The snowpack averages 40-85 cm at 2200m across the region. The wind slabs described earlier this week seem to be thin on immediate lees and of little consequence unless found on an ice climb.

Avalanche Summary

No avalanches observed or reported.

Confidence

Due to the number of field observations
