In sintesi

New snow and wind have created dangerous avalanche conditions at upper elevations. Human triggered avalanches are likely on steep wind loaded slopes. New snow is also stressing weak layers buried deeper in the snowpack. Avoid being on or under steep, rocky, wind loaded slopes and cross loaded gullies.

    Strong west/northwest winds with gusts in the 50s mph combined with up to 8 inches of new snow have formed wind slabs on lee aspects above 8000 feet. New slabs will be over a foot thick and likely be triggered by the weight of a rider. The danger will be highest above 9000 on steep, rocky and wind loaded slopes. Small avalanches have the potential to step down and impact deeper weak layers, creating large avalanches. Very strong winds may have loaded slopes and terrain features at lower elevations than you might expect.

    Strong winds from the road looking towards Two Ocean. Expect to find new wind slabs. Shooting cracks are a sure sign of instability.

    Weak layers of snow that formed in November are buried 2-3 feet deep beneath hard slabs. New snow from yesterday has added stress to these weak layers. Very steep, rocky, and wind affected slopes in the upper elevations are most suspect.  Triggering a smaller wind slab in yesterday’s new snow is a great way to impact deeper weak layers and cause a large avalanche. Give the snowpack time to adjust.

    A persistent slab avalanche on Barber's Point. This avalanche failed on weak snow formed in November. This terrain is wind loaded and very steep. A good slope to avoid today.

Avalanche Discussion

Buried weak layers on Togwotee need time to adjust to the new round of snow. While there is a lull in precipitation this morning, more is expected later today and overnight. Keep your head on a swivel out there and watch for signs of unstable snow, particularly on wind loaded slopes. Shooting cracks in the snow surface and collapses point to instability. Keep your slope angles low if you find these signs. 

If you get out riding today, please consider submitting an observation here. A simple picture or snow depth can make a big difference. Thank you!
