This winter's Persistent Weak Layer that formed in Jan/Feb is a very unique and unusual problem. We have very few avalanches in our database that break into sugary facets at this time of the season. Under normal situations, the big warm up a couple of week's ago should've ended this problem. But, the layer of facets has produced large avalanches since then. I continue to avoid the steepest northerly facing slopes. I'm not sure when we will be able to call those slopes 100% stable.
