Alpine temperatures will remain near -4 with freezing levels generally sitting near 800-1100 m. Wednesday should start to see a change as the next system sets up.

Snowpack Summary
The previous storm has formed new storm slabs which may have buried existing wind slabs. Storm slabs may be touchy and easy to trigger and may take a couple days before they settle out. An early November crust is located near the bottom of the snowpack under the past weeks snow accumulations. This crust has been seen from 1700 m to ridgetop on all aspects. Recent tests done have resulted in CTM-H ranges with SP characteristics. I have also received reports of a SH layer buried 100 cm down. The SH sits about 10 cm above the November crust and is 3-4 mm in size. Tests on this layer are in the mod-hard range with a SP characteristic. At this time the SH may just be localized and not widespread, not sure? Dig down, do some detective work, and see how the snowpack is looks, feels and reacts in your neck of the woods.Â
