Watch for decreases in stability on solar aspects over the next few days.  These decreases will be most apparent on thin, steep rocky slopes.

Summary

Confidence

Good

Weather Forecast

No new snow is expected over the next 24-48hrs.  Winds will remain calm at all elevations and temps will be above seasonal.

Avalanche Summary

No new avalanche observations.

Snowpack Summary

Little change, over the past 24hrs.  Melt Freeze crust on solar aspects up to 2400m.  Main concern is still the basal facets and triggerreing this weakness from a thin area.

Problems

Wind Slabs

An icon showing Wind Slabs
Winds slabs that developed last week still persist at treeline and above on N and E aspects.  Be careful not to trigger these problems from thin snowpack areas.
Be cautious as you transition into wind affected terrain.>Watch for whumpfing, hollow sounds, shooting cracks or recent avalanches.>

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

Elevations: Alpine, Treeline.

Likelihood

Likely

Expected Size

2 - 5

Persistent Slabs

An icon showing Persistent Slabs
Many large avalanches were observed over the past week failing on the October crust and ground.  Although no skier triggered events occurred on this later, it should still be in your head when thinking consequence.
Be aware of the potential for full depth avalanches due to deeply buried weak layers.>Be aware of thin areas that may propogate to deeper instabilites.>

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

Elevations: Alpine, Treeline.

Likelihood

Possible - Likely

Expected Size

3 - 6
