Highlights

Dangerous avalanche conditions exist above 8,500 feet. Yesterday, backcountry travelers triggered two slides on Teton Pass. One of these slides had a crown depth up to three feet, and the other occurred in low angle terrain. Similar large to very large persistent slab avalanches are likely to be triggered today on steep slopes. Remember, previous tracks are not an indication of stability with a persistent slab avalanche problem. These avalanches can be triggered remotely, and terrain below steep slopes should also be avoided.

    Persistent weak layers, which include faceted snow near the base of the snowpack and buried surface hoar, exist in terrain that held snow prior to Sunday November 24th. This terrain generally includes all aspects above 9,000 feet and northerly slopes down to 8,000 feet. Skiers and riders venturing into these areas are likely to trigger slab avalanches up to three feet deep. To avoid this hazard, knowledge of the extent and distribution of the weak faceted layers of concern will be essential.

Avalanche Discussion

( Discussion is generated from the previous day's afternoon forecast. )Light snow showers will continue overnight before tapering off during the day on Tuesday. Overnight lows in the mountains will be in the upper teens before rising back into the mid-teens during the day. Southwesterly to westerly ridgetop winds will decrease from 20 to 30 miles per hour to 15 to 20.Dangerous conditions exist in terrain that had an existing snowpack before Sunday, November 24th, and the general avalanche hazard is expected to remain Considerable on Tuesday. This terrain generally includes all aspects above 9,000 feet and northerly slopes down to 8,000 feet. Skiers and riders venturing into these areas are likely to trigger large to very large persistent slab avalanches.
