Primary Problem: Wind Slab
Bottom Line: Wind slab avalanches are easy to trigger and dangerous avalanche conditions will develop. Heavy snowfall is possible today and strong wind will continue, so the size, likelihood and distribution of avalanches will increase through the day. Loose snow avalanches and storm slab avalanches are also possible and can easily run long distances on the crust below the new snow. An additional problem south of Big Sky to West Yellowstone are deeper persistent slab avalanches breaking 2-5 feet deep on the weak snow that was buried in late January. Avoid steep wind-loaded slopes. Consider avoiding all slopes steeper than 30 degrees as heavy snowfall and strong wind increase the chances of human-triggered and natural avalanches through the day.

We observed two very recent natural storm slab avalanches about a 1.5 feet deep. One of them entrained a significant amount of snow an ran a long ways.
