Wind slabs at upper elevations will be the main concern.
A thick surface crust will present challenging travel conditions at lower elevations.

Avalanche Summary
A natural avalanche cycle occurred earlier in the week as rain and warm temperatures infiltrated the region. Slab avalanches up to size 3 were observed in the Smithers and Seaton areas.
Looking forward, lingering pockets of wind slab at upper elevations will be the main concern.
If you head to the backcountry please consider submitting your observations to the Mountain Information Network.
Snowpack Summary
Recent snowfall overlies a crust or moist snow from rain earlier in the week. Strong winds will create heavily wind-affected surfaces and redistribute dry snow into wind slabs.
We suspect two surface hoar layers in the mid-snowpack have been cleaned out by the rain.
Deeper in the snowpack, a rain crust from early November seems to be bonding well to the surrounding snow.
