GENERAL AVALANCHE ADVISORY

Heavy recent snowfall particularly on the west slopes of the Tetons combined with moderate westerly winds have created easily triggered soft slabs to two feet or more in depth on avalanche prone slopes at mid and upper elevations. At low elevations the snowpack is mostly stable. Two separate avalanche fatalities occurred Sunday. A backcountry skier who accessed the Clause Peak area by skis and snowmobile from the Cliff Creek Trailhead in Hoback Canyon is believed to have triggered an eight inch deep soft slab on a steep slope at an elevation of about 9,200 feet and was carried into a tree and did not survive. The second fatality was a skier on Survey Peak in Grand Teton National Park who also was carried into a tree. Our sincere condolences go out to those involved and their friends and families.

CHARACTERISTICS

Wind Slab

Avalanche problem rose
LIKELIHOOD: Likely
SIZE: Medium
TREND:Staying Same
PROBLEM DESCRIPTION
At mid and upper elevations new soft wind slabs or sloughs to two feet (or more on the west side) in depth will be easily triggered on a variety of aspects. The long, dry, cold period created excellent sliding surfaces of wind pack, sun crusts and faceted snow. Forecasted increasing winds will raise the sensitivity of slabs.
