There's been nothing that tells me that there's been any improvement with the mid winter Persistent Weak Layer in the lingering northerly facing upper elevation terrain. It's still there. While there's not a lot of loose snow available for transport, the strong wind most likely found something to blow around which actually would enhance the chances of triggering an avalanche. The wind takes snow from one location and deposits it in another. If it gets deposited in an area that already has an existing buried weak layer, it stresses that weak layer and makes it more sensitive. Just avoid that steeper upper elevation north facing terrain, I've given up on trying to figure out when things are going to be 100% stable.
