Highlights

Triggering an avalanche large enough to bury or injure a rider is likely in steep terrain today. Wind loaded slopes are most dangerous, but avalanches are also possible in steep terrain that is sheltered from the wind. Conservative terrain choices will be crucial in avoiding avalanches today.

    Heavy snowfall and strong wind over the last 6 days have created unstable conditions. Triggering a slab 1-4 feet deep in the recent snow is likely in wind loaded terrain in the middle and upper elevations today. Avalanches have the potential to break farther and wider than expected. Shooting cracks and audible collapses are clear signs of unstable conditions. However, these signs may not be present before triggering. Give all steep terrain a wide berth and be aware of steep slopes above you today.

    Weak snow that formed in November sits near the base of the snowpack in the majority of terrain above 8,500’. Loading from heavy snowfall and strong wind is stressing these weak layers making them more likely to fail. Avalanches in the upper portion of the snowpack have the potential to step down to older weak layers and create very large avalanches. This is most likely to occur in very steep terrain that faces east through north.

    Two recent human triggered avalanches have been reported involving weak snow near the ground. Both occurred in steep, treed terrain that is sheltered from the wind. No signs of instability were observed prior to triggering these avalanches.

Avalanche Discussion

A series of powerful storms has brought heavy snowfall and strong winds to the Togwotee area. Over the past six days Togwotee has received 2-3 feet of new snow with up to 3 inches of Snow Water Equivalent. This an impressive load in a short period of time. Both human triggered and natural avalanches have been reported in the past several days. These events are clear signs that the snowpack is unstable and needs time to adjust. A lull in precipitation is expected today before another round of snow on Wednesday. As a result, expect avalanche hazard to plateau today and increase late tomorrow and Thursday.
