Togwotee Pass

At the upper elevations yesterdays strong westerly winds may have formed small pockets of shallow wind slab, up to eight inches deep. These small wind slabs could pose a hazard above cliff areas and terrain traps and in steep couloirs and chutes. The interface between a late October snow surface and snow that fell in early November produced large slab avalanches on east and northeast aspects in the Teton Range ten days ago. This problem layer exists on northerly aspects above an elevation of 8,500 feet in the Togwotee Pass area and warrants careful assessment and consideration with respect to terrain choices.

( Discussion is generated from the previous day's afternoon forecast. )Skies will be mostly clear overnight and into the morning hours. Increasing clouds are forecast for the afternoon, ahead of the next storm system. Temperatures will drop into the lower teens by morning and rise into the 20s and 30s during the day. Winds will decrease overnight and are expected to be from the west-southwest at 12 to 20 miles per hour. Mostly stable snow exists. The general avalanche hazard is forecast to be LOW. Today’s westerly winds likely formed some small pockets of shallow wind slab on leeward aspects at the higher elevations. In steep, north facing avalanche paths the interface between a late October snow surface and snow that fell in early November produced large slab avalanches on November 4 & 5. This layer warrants careful assessment and respect.
