Due to the number and quality of field observations on Friday

Problems

Storm Slabs

30 cm of storm snow has been transported by NW to SW winds. These slabs are sitting on a weak faceted base and/or SH.

The new snow will require several days to settle and stabilize.Use caution in lee areas in the alpine and treeline. Recent storm snow has formed touchy slabs.

Aspects: North, North East, East, South East, South.

Elevations: Alpine, Treeline.

Be cautious of sluffing in steep terrain.

Aspects: All aspects.

Elevations: All elevations.

Likelihood
