Weather
Some call me a pessimist but I'd rather be pleasantly surprised than greatly disappointed! At the end of the day, the storm produced 9 inches of snow at 0.9 inches of Snow Water Equivalent (SWE), your standard 10% density powder snow. I expect we could have a foot or more of new snow up high. Pre-frontal southwest winds cranked in the 25-35 mph range but backed off a solid 10 mph when the snow started to fall. They shifted to the northwest around dinner time last night where they remain this morning.
Cold and clear conditions are on tap today with light to moderate northwest winds and high temperatures at 10,000' barely breaking 20F. Clouds will again start to build on Tuesday ahead of the next system to affect our area Tuesday night into Wednesday. It looks similar to the last event, keep your fingers crossed.
General Conditions
Conditions prior to the storm were quite thin as evidenced in the photo below. Note the areas of contiguous snow with the least amount of rocks poking out. This is the kind of terrain where you are most likely to trigger an avalanche.
With 9-12 inches of new snow falling on top of pre-existing, weak, faceted snow, we've developed our first avalanche problem. For now, expect avalanches to be confined to the new snow, particularly in areas where wind has aided in the distribution. Suspect steep slopes with an accumulated 8 inches or more of new snow. Also pay attention to loading patterns and look for drifted areas such as the leeward sides of ridge crests, gully walls, and other terrain features. Over time, this new snow will stiffen and consolidate forming a more widespread slab. With weak faceted snow underneath, this will likely turn into a persistent weak layer problem, especially when more snow is added mid-week. Stay tuned.
It's never too early to start thinking about avalanches. Here are a few things to consider doing:
