In sintesi

Triggering avalanches remains a possibility today. You’re most likely to trigger a slide where recent winds have drifted snow over the weak layers buried 1-3 feet deep. Look for signs of drifting near ridge tops and beware of very steep or rocky areas where this layer of weak snow may be more sensitive to triggering.

    Slabs can be triggered in very steep terrain features, such as unsupported slopes above cliff bands. These slabs could be soft or hard with depths up to 3 feet at the higher elevations. Though this avalanche problem appears to be on it's way to dormancy, continue to exercise safe travel techniques and look for this problematic layer, especially in steep and exposed terrain.

Avalanche Discussion

A strengthening trend is evident in the snowpack in most areas, though the weak snow layers still show a tendency, albeit a stubborn tendency, to propagate a crack in stability tests.  The Togwotee area, along with lower elevations in the Greys and Tetons, has a shallow snowpack with poor structure and well developed facets. However, less snow and therefore less slab development has resulted in a less widespread problem until additional loading occurs. Low desnity snow has been drifting and may have formed small and shallow wind slabs near ridge tops. Look for cracking as you approach wind affected snow.
