Problems
Wind Slabs
Some more snow and strong southwest wind may form new wind slabs in lee terrain features. Use added caution when entering slopes adjacent to ridges.
- Be careful with wind-loaded pockets, especially near ridge crests.
- Expect conditions to change rapidly with aspect and elevation.
- Use small slopes without consequence to test the bond of the new snow.
Aspects: North, North East, East, North West.
