Highlights

Some uncertainty regarding the potential for humans to trigger large slabs avalanches persist above an elevation of 8,500 feet in steep north facing avalanche paths. The problem layer is the interface between a faceted old snow surface that formed in late October and up to three feet of new snow with over three inches of moisture that fell during the first five days of November. Due to the uncertainty of this assessment and the consequences involved, a conservative approach to suspect terrain is warranted.

    The potential for humans to trigger a slab avalanche up to three in depth in steep north facing terrain continues to decrease. Some slopes that held snow from October are stable, and others remain suspect. This uncertainty is based on elevation, aspect, snow depth, the presence or absence of crusts and how the slope was loaded. In this situation, snow pits are useful for identifying snow structure. However, when evaluating the snowpack, remember that stability tests should be used to test for signs of instability, and the absence of significant test results should not be used as an excuse to ski or ride a slope.

Avalanche Discussion

( Discussion is generated from the previous day's afternoon forecast. )A quick moving system will swing through the area tonight and Tuesday. Light snowfall is forecast to begin in the morning and result in accumulations of 1 to 3 inches in the mountains by evening. Temperatures will drop in the 20s. Southwest winds will increase to 25 to 35 with gusts to 50 miles per hour.It seems unlikely that a human could trigger a large slab avalanche on the October/November snow interface. Suspect slopes for that scenario would be north facing avalanche starting zones and cliff areas that are above an elevation of 8,500 feet. Due to the uncertainty of this assessment and the consequences involved, a conservative approach to suspect terrain remains warranted. The general avalanche hazard is expected to be LOW on Tuesday in the Teton and Southwest Trails area and MODERATE above an elevation of 9,000 feet in the Togwotee Pass area.
