Strong winds since Thursday's storm have moved all available snow to lee-facing slopes. North through east to south-facing slopes near and above treeline are the most dangerous today and should be avoided. We have also received reports of dangerous wind-slabs in open below treeline meadows, so do not blindly jump onto steep slopes in below treeline areas either.
It may be a few days before we know the extent of the avalanche cycle that this unusual snow event triggered, but from what we can tell it seems like most avalanches broke within or just underneath the storm snow. These avalanches were two to three feet deep and were large and dangerous. As you would expect with a storm with this high of precipitation intensity, we have also received reports of dangerous avalanches breaking near the ground or on mid- to upper-pack layers such as near-surface facets and facets around crust. The crust-facet combos are more prevalent on sunny slopes and could be buried 3 to 5 feet deep at this point. If you trigger an avalanche on one of these persistent weak layers it will most likely be inescapable.
Snow continues today with up to 10 inches possible by Monday afternoon. The new snow will be low density., and will most likely not add enough weight to trigger another natural avalanche cycle. Slopes that continue to receive wind-drifted snow will continue to be dangerous and loading will have to stop before these slopes become more stable.
The bottom line is that this was a very large load in a short period. The general trend of the snowpack is good on a seasonal scale as we are building a deeper and stronger snowpack. For today, very dangerous conditions exist and the snowpack needs some time to adjust to this rapid load.
If you are traveling in the Sangre de Cristo Mountains, these mountains received about a foot of snow with strong winds. Although this a lot less snow than the San Juan Mountains, the snowpack is much, much weaker and avalanches on deeper layers or the ground are more likely. This problem in the Sangre de Cristo zone will be slow to change.
