In sintesi

Thanks go out to the heroic efforts of Teton County Search and Rescue volunteers who responded to a human triggered slide on Jackson Peak late in the day on Sunday. Additional information on this event and another slide which occurred yesterday below Two Ocean Bowl can be found on the Avalanche Event Map page. At the upper elevations, backcountry travelers venturing into steep, northerly facing avalanche terrain could trigger dense slabs up to 30 inches in depth. Daily warming will makes these slabs more susceptible to failure. Avalanches are unlikely at the mid elevations, and very shallow snow depths and areas of bare ground exist at the lower elevations.

    Some potential remains for skiers and riders to trigger persistent slabs up to 30 inches in depth on steep, northerly aspects above an elevation of 9,000 feet. These slabs lie upon a mid-October drought surface that is comprised of faceted snow. Thin areas of these slabs may be potential trigger points and previous tracks on these slopes may not be an indication of stability. Be particularly suspect if these areas have evidence of recent wind loading from late last week.

Avalanche Discussion

Mostly cloudy skies with periods of mountain snow showers or flurries. Daytime highs will rise into the 30s and 40s. Winds will be west at 15 to 20 and increase with gusts to 30 miles per hour late in the day.At the upper elevations (above an elevation of 9,000 feet) unstable slabs up to 30 inches deep lie upon a persistent weak layer on steep north facing terrain. These slabs can be triggered by the weight of a single person; however existing tracks on a suspect slope may not be an indication of stability. Areas were this instability is prevalent have faceted snow that formed in October at the base of the snowpack. Avalanches are unlikely below an elevation of 9,000 feet. The general avalanche hazard is expected to be MODERATE at the upper elevations and LOW at the mid and lower elevations.
