Summary

Problems

Loose Wet

An icon showing Loose Wet
Cool temperatures are keeping the snowpack stable. There's 5 cm of new snow at higher elevations over a supportive crust. Good stability in the morning may quickly deteriorate with daytime warming. Watch for moist sluffs gaining mass on this crust.

Aspects: All aspects.

Elevations: All elevations.
