Primary Avalanche Problem
DescriptionKeep an eye out for windslabs of new snow at uppermost elevations.
This should have bonded fairly well to the wet snow surface yet be aware that with high winds and high precipitation volumes windslabs will be questionable in places.
With cooler temps in place this layer will bond and heal quickly over time. Time is your friend.
Secondary Avalanche Problem
DescriptionWith 6.6" precipitation over the last 6 days be aware of rotten snow at mid to lower elevations. This snow will not bond well to other things until it cools back off to below the point of freezing.
Be aware that you still have a giant slurpee... that has most of the liquid drained out of it... but not much keeping it in the glass right now... it will turn back to a bag of ice in the next day but it needs time to heal.
Be aware of steep open rock or grassy faces and places that have fewer anchors or steep convex rolls adding stress to the slab through creep and glide...
This danger will subside greatly over the next 24 hours with additional cooling.
