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 rode out Lionhead Ridge and around the north end to the head of Targhee Creek. Skies started overcast, but cleared through the day as wind calmed from moderate to light out of the west and southwest.... there were two or three shallow small wind slabs below Lionhead Ridge.

Also, on our way out we saw an avalanche in Airplane Bowl that had been triggered during the day today. This slide also broke on the persistent weak layers, 2-3' deep, 150' wide.

Caught: 0 ; Buried: 0

A rider triggered a huge avalanche in the uppermost reaches of Targhee creek. We discovered it on our way out. The best we could tell looking at their tracks was that they had no idea they triggered it, even though part of their tracks were swept away.
