Avalanche Summary
A skier triggered a small wind slab in a lee feature on the north side of Mt Cheops Saturday. Glide cracks have been on the move lately, with a size 2 glide slab avalanche from the S aspect of Mt. Tupper early on Saturday, a size 3 from S Mt. Tupper on Friday.
Confidence
Due to the number of field observations
Problems
Wind Slabs
New snow and moderate winds Saturday built fresh windslabs in lees. These may sit over a crust on slopes with sun exposure.
- Use caution above cliffs and terrain traps where small avalanches may have severe consequences.
- Watch for shooting cracks or stiffer feeling snow. Avoid areas that appear wind loaded.
Aspects: North, North East, East, South East, South, North West.
