Travel and Terrain Advice
This is a day to be on the lookout for unstable snow that remains in certain terrains. Generally, a significant amount of snowfall will continue to cause instability for several days. The speed of its resolution varies from place to place. Watch out for slabs that form on isolated slopes, convexities, or extreme terrain where the terrain is not conducive to supporting snowpack. If you are a little unsure about judging snow conditions, consider using terrain to provide a margin of safety. You can easily find a safe line by choosing a low angles ridge or a gentle slope.
