Kernpunkte

Yesterday, two large avalanches were remotely triggered by backcountry travelers in the Snake River Range and the Wyoming Range. Both these events are indications of the dangerous avalanche conditions involving persistent weak layers, which exist in the forecast areas. On Togwotee Pass, it remains possible for skiers and riders to trigger small to large slab avalanches on avalanche-prone slopes. Today’s warming temperatures and sunshine could increase the sensitivity of these slabs. Expert terrain evaluation skills are essential and conservative terrain choices are warranted.

    Slab avalanches that could severely injure or kill a person can be human triggered on avalanche prone slopes. These slabs could be one to three feet deep above an elevation of 8,000 feet, where the hazard is moderate. These avalanches could be triggered on suspect slopes that have existing tracks. The avalanche hazard is low below that elevation, where avalanches are unlikely except on isolated terrain features.

Avalanche Discussion

( Discussion is generated from the previous day's afternoon forecast. )A weak weather disturbance will pass to the southwest of the forecast area and bring light snow tonight that is expected to last over the Southwest Trails area into tomorrow morning. Accumulation amounts are expected to be an inch or less. Partly cloudy skies will clear during the day. Temperatures should start cold in the single digits to low teens and then warm into the teens and twenties. Northerly winds are expected to be light. Skiers and riders could trigger small to large persistent slab avalanches on a variety of aspects and elevations. The daily warming along with sunshine may increase the potential to trigger slab avalanches. Above 7,500 feet, in the Southwest Trails and Teton forecast area, where slab depths could be two to four feet, the avalanche hazard is expected to be Considerable. In the Togwotee Pass forecast area above 8,000 feet, where slab depths could be one to two feet, the avalanche hazard is expected to be Moderate. Careful evaluation of the snowpack and safe terrain selection is warranted to travel in the backcountry.
