Avalanche Summary

Snowpack Summary
Up to 30 cm of recent snow could fall by the end of the day Saturday. This will add to the 5 cm that buried a variety of layers including surface hoar and facets in sheltered terrain, a crust on south and west-facing slopes as well as old wind slab on exposed terrain.
The widespread crust buried in early February is down 5 to 40 cm. This crust may have a layer of facets above it.
The remainder of the snowpack is settled and not concerning.

- Watch for fresh storm slabs building throughout the day.
- Seek out sheltered terrain where new snow hasn't been wind-affected.
Avalanche Problems
Persistent Slabs
The crust that was buried in early February has weak, sugary facets or surface hoar on top of it, making it a bad weak layer.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood: Possible - Likely
Expected Size: 2 - 3
Storm Slabs
Wind and new snow will form storm slabs throughout the day. These slabs will be most reactive where they overlie surface hoar, facets, or a crust.
Aspects: All aspects.
Elevations: All elevations.
Likelihood: Possible - Likely
Expected Size: 1 - 2
