FROM AVALANCHE CANADA:

Travel and Terrain Advice

Avoid freshly wind loaded features, especially near ridge crests, roll-overs and in steep terrain.

Avoid steep, rocky, and wind effected areas where triggering slabs is more likely.

Minimize your exposure time below cornices.

The more the snow feels like a slurpy, the more likely loose wet avalanches will become.
