If you're watching our local conditions closely (and you should!), you'll know about our deeply buried persistent weak layers and IPAC's discussion of slabs stepping down through the snowpack to create large avalanches. For example, from @Mtnbikemelissa 's IPAC discussion this morning for the St Regis & Silver Valley region — "This persistent weak layer problem is becoming lower probability to trigger because it is buried so deep, but higher consequence if it does slide...Give them a wide berth, even a small wind slab has the potential to create an avalanche that could step down and trigger a much larger one on the buried persistent weak layer." Avalanche Canada just did a presentation covering the contributing factors and concerns while identifying the key words in the discussions (Melissa uses several above). This presentation is well worth 30 minutes of your time, just over an hour if you hang around for the Q&A portion.
