Terrain and Travel
- Storm snow and wind is forming touchy slabs. Use caution in lee areas in the alpine and treeline.
- Avoid freshly wind loaded features, especially near ridge crests, roll-overs and in steep terrain.
- Shooting cracks, whumphs and recent avalanches are strong indicators of an unstable snowpack.
- Use small low consequence slopes to test the bond of the new snow.
- Avoid terrain traps where the consequence of any avalanche could be serious.
