The new snow isn't going to be much of an issue today. The big concern is if/when we get enough to start overloading the deeper buried faceted weak layers from earlier this season. This is going to be a tricky situation and something to pay close attention to.
For today, chances for triggering a deep avalanche aren't all that likely. But, it is still a roll of the dice. Upper elevation north through east facing very steep slopes are where you'd find trouble.
My co-worker Drew Hardesty hosts podcasts for the UAC. He and I had a conversation years ago that he decided to publish. It will give you insight to me as a forecaster but more importantly there is lots of information about Persistent Weak Layers, how they form, problems with them and how to deal with them. It is pertinent info for this season as we've had layers of loose sugar nagging at us all season and they continue to be a concern.
