Avalanche Summary

There are no recent significant observations to report at this time. If you are spending any time in the backcountry, send us your observations. Every bit helps. Please send your observations to: [email protected]

Snowpack Summary

20 - 30 cm of low density storm snow rests on a generally strong midpack. Operators in this region are reporting minimal wind effect in the alpine and at treeline. Persistent and Deep persistent instabilities (surface hoar and an early November crust, respectively) located in the middle and near the bottom of the snowpack may still be a concern but there's little recent evidence of them being reactive. It is important to know that we have very limited observations for this region. Digging down and making your own observations, especially in thinner snowpack areas, remains a good idea to assist safe slope selection. You're looking for weak layers that pop or drop in stability tests.

Avalanche Problems

Wind Slabs

Recent southerly and westerly winds have created windslabs in the lee of terrain features.
Use ridges or ribs to avoid pockets of wind loaded snow.>Be cautious as you transition into wind affected terrain.>Stay well to the windward side of corniced ridges.>

Aspects: North, North East, East.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 3
