Expect 5-10cm over next few days and temperatures -10 to -15. Warming up slightly from the frigid weekend but still feeling cold with brisk wind.

Snowpack Summary

Variable wind slab on lee features at all elevations. Recent cold conditions facetting the surface. Variable snowpack depths with pockets up to 1m deep. October raincrust sporadically distributed.
