Avalanche Summary

No new natural or skier triggerred avalanches were reported or observed.

Snowpack Summary

Little change over the past 24hrs...  Surface hoar up to 15mm can be found below 2200m and a thin MFC is being observed on steep solar aspects up to 2600m.  These two layers will become persistent weak layers once the new snow arrives.

Avalanche Problems

Persistent Slabs

Stiff windslabs can be found along ridgelines and in gullied terrain. The entire snowpack is likely to be involved in any avalanche that occurs on this layer.
Be aware of thin areas that may propogate to deeper instabilites.>Be aware of the potential for wide propagations due to the presence of hard windslabs.>

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

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 2 - 5

Storm Slabs

New storm slabs are forecast to develop overnight. 
Caution in lee and cross-loaded terrain near ridge crests.>Avoid freshly wind loaded features.>
