Not much of a change on thursday except we can expect to see the winds increase slightly out of the west. Temperatures will be around -10C under a ski that is mainly a mix of sun and cloud.  

Avalanche Summary

No new avalanches were observed.

Snowpack Summary

The alpine has widespread wind slabs in the upper 40cm that are still providing good skiing as long as they are not too dense. Take the time to investigate these wind slabs so as to not be surprised in the density change. Cracking around your skis is a good indicator of this density change. The Jan 29 interface is down about 50-60cm and is producing a shear.
