Moderate

Avalanche Summary

No new avalanches have been reported since Tuesday.

Snowpack Summary

Around 10 cm of snow came with strong southwest wind and is now redistributed into lee areas, potentially creating wind slabs. This now sits on a crust on south slopes, wind-affected snow in exposed areas and hard snow in lees.

The snowpack depth varies greatly as well, windward slopes may only have 50 cm on them while leeward slopes could have as much as 150 cm.

Check out this MIN from the South Rockies Field team on Friday.
