    Continued south west winds have created fresh wind slabs in lee alpine terrain. These wind slabs are reactive to skier triggering.

For Tuesday scattered flurries with accumulations near 10 cm at treeline forecasted for along the Divide. Day time high temperatures of -8 in the alpine.

Snowpack Summary

The recent storm snow is settling and bonding to itself, however there is still a weak bond at the storm snow interface down 30-50 cm. South west winds in the past 48 hours have started to create touchy wind slabs in lee alpine terrain. These wind slabs are reactive to skier triggering.

Avalanche Summary

Natural and skier triggered avalanches up to size two are being observed at tree-line and alpine elevations throughout the region. A skier remote class 2 was triggered on a SW aspect near tree line in the Emerald Lake vicinity today.
