The focus is still on all the weak sugary snow that is in various layers within our snowpack. Persistent Weak Layers of sugary facets exist in many locations ranging from the bottom of the snowpack, through the entire snowpack in shallow spots, and a layer near the surface as well. There are two situations to keep in mind today:
- Wind drifted snow. We've had weeks of wind on and off. This wind formed drifts, slabs, and cornices in the high terrain. Many of these will be stubborn and stay in place. Some may crack out. Faceted snow is the wild card and my bet is that anything that cracks out today will break into a layer of facets.
- Wet snow in the low and mid elevations. The wet avalanche activity I've seen this week all involved buried facets as a weak layer. With the gradual cooling trend, I'm thinking we're past the hump where we'll see much wet snow avalanche activity. However, you won't find me monkeying around in unconsolidated sloppy wet snow around any steep slopes today. This issue will pass as temperatures continue to cool down this weekend but use caution still today.
